  • Embedding a WMV file on the web via URL in a Powerpoint presentation

    - by Dave
    I've got a situation where I want to distribute a Powerpoint presentation to several people. I want to be able to embed several large videos in this presentation by linking to a URL, for the following specific reasons: the videos are highly confidential, and I would like to be able to delete them at some later date, but still allow them to see it in the presentation while it is online. I want to send the presentation via email (so it should be small), and put the links on a server with a faster upload speed Maybe I'd like to change the video at some point without changing the presentation One option that addresses #1 is to hook up a webcam and allow them to see video stream from the office, but our upload rate is too slow for this to be a viable option. I've tried embedding a video and giving Powerpoint the URL. It seems to work initially, because the first frame appears in my slideshow. However, when I play the slideshow, nothing happens. I looked at the network traffic on my computer, and nothing was getting downloaded from the remote server. Any suggestions on how to make this work, or how to at least satisfy the criteria listed above would be great!

  • Recommendations for hosting large videos

    - by Clinton Blackmore
    I recently created and put a 45-minute, 300 MB video file on my website and told a mailing list about it. Checking my site stats, I see that I've used 20% of my "unlimited" bandwidth for the month. As I want to be able to have several videos like this, clearly, I need to consider other options. The appeal to hosting files as my own site (aside from the supposedly unlimited disk space and bandwidth), is to be able to have control over the format, resolution, and quality of the video(s), as well as to ensure that it is clear that I'm the copyright holder (although the videos will be under a creative commons license). I find that for the screencasts I'm making, having a high resolution (say 3/4 of 1024 * 768) really makes seeing what is going on on the screen easier. It is also always a plus to not have the experience marred by advertisements. One more wrench to throw in is that while the videos are non-commercial, they do promote a club, and it seems that that falls afoul of some terms of services (especially for free services; while free is very nice, I will certainly consider putting up some money.) What recommendations do you have for (fairly) long, high-resolution videos? Should I look in depth at sites like YouTube and Vimeo, should I be considering a filesharing site [I have no qualms with someone downloading the entire video first -- I wouldn't want to watch 45 minutes in my browser!], hosting files with Bittorent (ugh -- I think that'd reduce my audience), or should I be looking into other web hosts (and if so, who?)

  • ffmpeg: converting an avi to a reduced, shareable flv/mp4...

    - by meder
    I recently followed a guide and recompiled my ffmpeg so x264 is enabled. I used some generic settings to convert my 700 MB avi file to a mp4 file, the result was a 407MB mp4 file. The original avi file's settings: Codec: DX50 Resolution: 704x304 Frame rate: 23.976023 Stream 1 Codec: mpga Type: Audio Channels: 2 Sample rate: 48000 Hz Bitrate 179 kb/s Command I used: ffmpeg -i input.avi -acodec libfaac -ab 128k -ac 2 -vcodec libx264 -vpre hq -crf 22 -threads 0 output.mp4 The settings of the output file (output.mp4): Codec: avc1 Resolution: 704x304 Display resolution: 704x304 Frame rate: 11.988011 Stream 1 Codec: mp4a Type: Audio Channels: 2 Sample Rate: 48000 Hz Bits per sample: 16 Bitrate: 1536 kb/s The quality of the output mp4 is pretty nice, it seems as if it's pretty much the same as the original source. However, I'm trying to reduce the filesize and I'm not really sure whether I should go with an flv format or keep it mp4. The advantage the flv would have obviously is that it would be playable with a flash player ( I have come across some swf players which take a flash parameter to play an flv file ).. but maybe I could use the video element, as I'm only going to be displaying this video privately so I don't have to worry about supporting legacy browsers such as IE. Can someone recommend some settings to specify in order for the filesize to be around ~100-150MB or so? I don't mind a reduction in quality, nor do I mind resizing it - I was going to do it initially but I wasn't sure what the guidelines were ( if any ) for dealing with resolution.. since this video's is 704x304 would it still be ok if I forced it into one that isn't perfectly fit for the aspect ratio? I have no clue about that part. I realize that I could have probably specified 28 instead of 22 for the CRF, I'm not sure if I should do that as opposed to maybe specifying smaller resolution, which might make it smaller as well?

  • How to Eliminate Black Bars from Powerpoint videos ?

    - by appu
    Hi, I am running a digital signage system for my client. The basic installation is a vertically oriented 42" LCD TV with a 1920x1080 screen resolution (reverse of 1920x1080 when setup normally, i.e. landscaped). Please check out the following link for a basic screen divisions layout I want to setup. http://flickr.com/photos/55097319@N03/5410208856 In the division labeled "ppt" I plan to run a powerpoint presentation. The screen division is 360x1476 resolution. As there isn't an option in powerpoint to specify slide size in terms of resolution so according to this article on indezine http://indezine.com/products/powerpoint/books/perfectmedicalpres02.html to get a screen resolution of my preference I divided 360 and 1476 each by 72 which gives me 5"x 20.5" as the slide size for my ppt. After setting up slide size as per above dimensions, I used sizer (http://brianapps.net) to resize my ppt window to 360x1476 so that when I record I do not get any black bars. But after launching recording there are side black bars visible which camtasia records and brings-inside cam studio with black bars. http://www.flickr.com/photos/55097319@N03/5409597049 My question is that after doing the above and as explained in the following video link why do I still get black bars. http://feedback.techsmith.com/techsmith/topics/eliminate_black_bars_in_your_powerpoint_recordings Is there an option in camtasia to stretch the recording to cover up black bars or any other alternative way I can get rid of those black bars while I get a ppt recorded as per my preferred dimensions. Notes: In the techsmith video above it asks to adjust my desktop screen resolution which my display chipset does not allow me to set. I set up show in powerpoint to be "browsed by an individual(window)". Also signage software only supports swf's and video file formats natively and not ppt, pptx etc. Thanks bhavani.

  • Windows XP Video Configuration Issues

    - by Matt
    Recently I had my motherboard burn out on me. Needing the machine for work, I purchased a different motherboard and installed that. Generally a reinstall of windows is good at that point but I am not in a position to do that so I just decided I would live with it for now. When I can log-in, everything works fine, what doesn't is getting to the log-in prompt to begin with. Basically when I first installed the new mobo, every time I rebooted the machine, I would not get the windows login prompt. One of the monitors would receive a signal but the screen would be black. Moving the mouse would not show the cursor and hitting the up arrow key and typing my password and hitting enter (which will normally log you in without mouse) wouldn't change anything. I would then change the monitor configuration around (2 lcd's and a crt) and reboot and at least one of the monitors would work and display the login prompt. I could then go into display properties and turn on the other monitors. However if I rebooted again, I would get the black screen on one monitor again. I would then have to change the configuration again to one not used before and I could re-do the manual setup at that point. I think windows saves the configurations so I had to keep giving it new ones. Needless to say I've been trying to not turn off my machine. Early this week I actually got the prompt to come up without playing musical monitors. Thinking everything was getting better, I found no harm in rebooting to install the latest windows updates. Boy was I wrong. Now no matter what I do I can't get a windows log-in prompt to display. I've tried almost every conceivable combination. The new mobo has onboard video so I set that in the bios (yea bios screen always displays fine, its not until windows boots that there is a problem) to be the primary video. Still no luck. I have two other graphics cards in the machine which I'm using. Tried all kinds of configurations between those and on-board but still get this black screen of death. I read somewhere that deleting the video drivers would reset the configurations. I logged into safe mode (which works on one monitor), and uninstalled the display drivers. Still no luck and when I booted back into safe mode, it wanted to install new hardware and the display adapters weren't there as expected. Anyone have any ideas? A fresh install would be a pain and I might be getting my old board back from RMA soon so not sure I want to go through with that just yet. Only thing I can think of is to continue to try other combinations like physically removing the graphics cards. They are both EVGA 8600 cards and the windows boot screen does display fwiw.

  • h264 inside FLV container vs. MP4 container?

    - by Gotys
    I am developing a tube site, and currently having issues with h264 format . By looking at youtube, I noticed they are putting their hi-def videos into mp4 container, so logically I did the same. Next, I installed mod_h264_streaming for lighttpd to make streaming and timeline-scrubbing work. Problem is, that large files (500mb+ at somewhat high resolution) take for EVER to even start buffering ( I read the flowplayer or other flash players need to download metadata first) . I moved the xmov atom to the front of the file with MP4Box (i tried qt-quickstart too) , and the problem didn't go away. Next I read online I need to interleave audio tracks, so I did that too. No change in slowness. So I tried putting the same exact h264 movie into an FLV container, and the playback buffering starts almost instantly - no slowness. So what am I missing here? Why would I choose MP4 container with mod_264_streaming module , which seems super-slow over a regular FLV container with lighttpd's built-in mod_flv_streaming ? Obviously many websites pick mp4 container , but I fail to understand why ? And as a side question - I tried using HTML5's VIDEO tag to try the same h264 MP4 movie, and the scrubbing is LIGHTING FAST! I looked into lighttpd's log file, and i noticed taht Flash Players append video.mp4?start=234 each time timeline is scrubbed, wheres HTML5's video tag does no such thing . Is this some sort of limitations of Flash ? Why Can't flash streaming be same fast as HTML5 streaming? Thanks to ALL who can help. I very much appreciate this community.

  • Is there a good alternative to Videora iPod Converter?

    - by Richard
    I use Videora to convert my videos (in DivX/XviD format) to something I can play on my iPod Classic. I really dislike it. It's clunky, riddled with adverts, sometimes doesn't convert properly (the infamous "invalid public atom" error - see Google for more) and has a UI that truly stinks. On the upside, it's free, accepts a list of video files (via the oddly hard to find "1-click convert" button) and just gets on with the converting as it already knows the correct settings for my iPod. One final nice touch is that once they are converted, it'll automatically upload them into iTunes. Are there any alternatives which have all the upsides but none of the downsides? Bonus points if they can set the metadata in iTunes correctly for TV shows (season, show, episode) and delete the converted file afterwards (as my iTunes settings means that a copy is made elsewhere). I've looked at a bunch of applications (handbrake, virtualdub, mediacoder, format factory, any video converter, convertxtodvd) but many of them fail the "just select a list of files and get on with converting" test - let alone all the other features I want. I have no desire to individually set the video size of each file or the codec or the post-processing options. I'm currently using the command line version of HandBrake (handbrakecli) and a hand-written DOS batch file to go through every file in a folder and convert it. It does most of what I want, just not in a very slick way. Can anyone recommend anything better? It needs to work on Windows 7 and be free.

  • Webcam security camera software that runs as a service

    - by hurfdurf
    I've been looking for Windows webcam software that will run as a Windows service without any user login. The goal is to use the webcam as a cheap security camera and log the results to secure networked storage (windows share, not FTP). The requirements are: Motion detection Video capture Runs as a service (should start recording immediately after reboot) Nice to have: Round-robin storage, e.g. 10Gb limit, oldest files overwritten/deleted when space gets low I've read the other webcam questions but still haven't stumbled across anything suitable. Evaluations thus far: Title MotionDetect Service Snapshots Video SpaceLimit License Yawcam Yes Yes Yes No No GPL WebCam ZoneTrigger Yes No Yes Yes No Commercial Dorgem Yes No Yes Yes No GPL AbelCam Yes No Yes Yes No Commercial Logitech Yes No Yes Yes No Paired with camera IspyConnect Yes No Yes Yes Yes Free SecureCam (SourcefoYes No Yes Yes No GPL AbelCam Yes No Yes Yes No Commercial Active WebCam Yes Yes(?) Yes Yes Volume Free Commercial WebCam Surveyor Yes No Yes Yes No Commercial WebCamsPy NA NA NA NA NA GPL Camera: Logitech Webcam Pro 9000 Windows 7 32-bit WebCamsPy failed to initialize so couldn't be tested So far, the contenders: Active Webcam comes the closest, and claims to run as a service, but i haven't been able to get it to record after a cold boot even though a service is running. Yawcam can be set up as a service but doesn't record video. IspyConnect has exactly the type of space limit I want and looks great, but doesn't run as a service (seems also to be a bit of a cpu hog) Any other suggestions? I'm locked into Windows so can't use linux Motion, which looks almost perfect. Any pointers to rich Windows webcam/motion detection libraries out there that could easily be turned into a command line program would also be appreciated.

  • Monitor attached to motherboard is out of frequency

    - by Neilvert Noval
    I don't know if this is appropriate to ask it here in superuser. Please, just route this to appropriate stackexchange site if found unrelevant. Here's my scenario. I have bought a new motherboard (MSI 785GT-E63). I already have an old CRT monitor connected to it. After I install a linux OS to it, my monitor will display that it is: Out of frequency. Current frequency is 89Hz. The operating output of my monitor is (around) 60-70Hz. I would like to get this thing work. How can I let my CRT display properly? I was thinking of lowering down video frequency output of my motherboard, but I can't find any settings on my BIOS setup. Additional info: My monitor is attached directly to the built-in video adaptor of my motherboard. (No additional video cards) Install of OS is complete without errors. Please help.

  • Reduce size of MP4

    - by testing
    I have a MP4 file with a lengh of 22:44. Here are the details: Video: width: 720 px height: 404 px data bitrate: 1022 kBit/s overall bitrate: 1182 kBit/s fps: 24 codec: H264 - MPEG4 AVC (part 10) (avc1) Audio: bitrate: 159 kBit/s stereo sample rate: 48 kHz codec: MPEG AAC Audio (mp4a) I thought I can reduce the current filesize (about 200 MB) by reducing the width and the height (420 x 236). I tried different programs: Handbrake, Format Factory, Next Video Converter and Super. The first three didn't worked as expected: Handbrake has a bug by setting the width and the height, the next two doesn't allow the fine setting of the videosize (only presets of width and height). Super seems to be the best, but I didn't found a setting which reduces the file size. I reduced the width and the height but only got 20 MB less. Now I tried the xth setting and I still get a too high file size. I want to reduce the filesize to 100 MB or less. The ouput format should be FLV or MP4, because I need this for flowplayer. Which settings of SUPER or which program should I use to reduce the file size? Of course the video should still be viewable.

  • I cut-to-move DCIM folder to ext SD when an auto android OS update popped up b4 I could choose target - Cannot recover 200+ photos

    - by ZeroG
    I was downloading my Exhibit II's DCIM camera folder (with month's of photos inside) to its external SD card, in order to transfer them into my laptop. In my overconfidence, I hurriedly chose cut-to-move (rather than copy-to-move) when KABOOM! —an automatic Android OS update popped up before I could choose the target!!! I figured everything was in cache & calmly tried to go through with the update. But that was not a typically seamless event. It showed downloading icon but hmm… since I rooted the phone it brought the command line up & recovery sequence. But neither Android nor I had yet downloaded any alternate custom ROM Files to internal SD to update from! So were they trying to make me unroot my phone by giving me some bogus update on the fly or just give me a hard time in trying to hand me down an unrooted ROM that I'd have to figure out how to root again? Yes, I know there was that blurb about overwriting a file of the same name but I was trying to shake the darn stubborn update being forced on my phone during this precarious moment. I thought I had frozen or turned off all those auto-updates previously. Anyway, phones are small & fingers are big (sigh)... I tried to reboot into safe mode but the resultant photo file was partially overwritten (200 files had names but Zero bytes in them). I thought maybe it was still hung in cache or deposited somewhere else but I have searched everywhere with file managers. Since I did not have Titanium backing up camera, photo folder or gallery, I cannot recover 200+ photos. Dumb. You can understand my dilemma as I am involved in the arts & although just a camera phone, most of these photos were historic & aesthetic or at least as to subject matter. Photo-ops don't reoccur. I have tried a couple of recovery apps from the market like Search Duplicates & Recover to no avail. I was only able to salvage stuff I'd sent out in messages. I've got several decades in computers & this is such a miserable beginner's piece of bad luck I can't believe it happened to me. They were precious photos! Yes, I turned on Titanium since & yes I even tried USB to laptop recoveries. Being on a MacBookPro I'm trying androidfiletransfer.dmg, but I'd have to upgrade to Peach Sunrise to get above Android 3.0 for that App to recognize the phone via USB & the programmer says installation zeros your data, so that pretty much toasts any secret hidden places where these photos may have been deposited. Don't want to do that & am still trying to find them. They certainly didn't make it to my external SD Card. If any of you techies out there know anything, please help & thanks. Despite decades of being in computing, unfamiliar & ever-changing hard or software can humble even the most seasoned veterans.

  • Anti Aliasing dead

    - by Gazoza
    I have a problem with anti-aliasing. No matter the software settings, it seems to be gone. I tried driver updating and reinstalling, cleaning of the hardware, different monitor with different cablies, OS reinstalling and changing, none of which helped. I decided to change the graphic card, but that didn't work either. Moreover, I have a distinct impression that the jagged edges are worsening as time goes by. I think this is a hardware-related issue, but I don't know exactly what to do. If anyone here had similar troubles, and/or has an idea how to cope with them, I'd be very grateful. My current card is a nVidia GT610.

  • Windows 7 losing one of my displays after restart

    - by j_kubik
    I have an Intel DZ68BC motherboard with Intel HD graphics card using two monitors (on DVI and on HDMI » VGA). My friend asked me to test if his NVIDIA graphics card works well on my computer (at his it was doing some trouble), so I inserted it in my computer, installed the NVIDIA driver and it worked quite well. Then I removed it, uninstalled everything NVIDIA-related I could find and switched monitors back to my Intel card. Since then after every system start/restart, the system sees only monitor on HDMI » VGA connector, completely ignoring the DVI monitor. I noticed that installing the Intel video drivers causes the system to recognize the second monitor if I don't immediately reboot. After a reboot, the system recognizes only the HDMI » VGA monitor. I also tried starting in safe-mode and using DriveSweeper to remove the remains of NVIDIA drivers. While it seems that some drivers were removed, the situation didn't change. Now I am out of ideas and I really wouldn't like to reinstall the system (again...). I also tried restoring the system to the state before this whole story, but it also didn't change anything. EDIT: I am still trying to troubleshoot this problem. The only point that I could start was driver re-instalation. I traced down the part that restores right settings to a call: C:\Users\Jarek\Desktop\GFX_Win7_64_8.15.10.2696\x64\Drv64.exe -driverinf "C:\Users\Jarek\Desktop\GFX_Win7_64_8.15.10.2696\Graphics\igdlh64.inf" -flags 20 -keypath "Software\Intel\Difx64" This call fixes my displays, and as workaround, I will add it for now to my autorun. I am still looking for better solution anyway... EDIT2: Using DriverView i made a list of currently used drivers both before and after fixing my display using above command. Then i compared logs: No drivers were removed by fixing command. Drivers added by fixing command: MS Remote Access serial network driver (asyncmac.sys) security processor (spsys.sys) Drivers that changed base address (indicates driver-reload?) Canonical Display Driver (cdd.dll) Intel Graphics Kernel Mode Driver (igdkmd64.sys) Monitor Driver (monitor.sys) Added drivers seem rather unrelated to the problem to me, reloaded drivers are just a cnsequence of installing new driver file so there is not much to go here... I really cannot make heads or tails out of it...

  • Determining a transaction fee before an order is processed

    - by Kenji Crosland
    When users make credit card transactions on my web app, I'd like to include the transaction fee on the confirmation page before the user makes the order. The thing is, there are different transaction fees for different cards. Is there a way to determine a transaction fee from the card number? I'm using Rails and ActiveMerchant, but I figure this question was applicable to other languages as well.

  • Android -- Can't play any videos (mp4/mov/3gp/etc.)?

    - by borg17of20
    Hello all, I'm having great difficulty getting my Android application to play videos from the SD card. It doesn't matter what size, bitrate, video format, or any other setting I can think of, neither the emulator nor my G1 will play anything I try to encode. I've also tried a number of videos from the web (various video formats, bitrates, with and without audio tracks, etc.), and none of those work either. All I keep getting is a dialog box that says: "Cannot play video" "Sorry, this video cannot be played." There are errors reported in LogCat, but I don't understand them and I've tried searching the Internet for further explanations without any luck. See below: 03-30 05:34:26.807: ERROR/QCOmxcore(51): OMXCORE API : Free Handle 390d4 03-30 05:34:26.817: ERROR/QCOmxcore(51): Unloading the dynamic library for OMX.qcom.video.decoder.avc 03-30 05:34:26.817: ERROR/PlayerDriver(51): Command PLAYER_PREPARE completed with an error or info PVMFErrNoResources 03-30 05:34:26.857: ERROR/MediaPlayer(14744): error (1, -15)03-30 05:34:26.867: ERROR/MediaPlayer(14744): Error (1,-15) Sometimes I also get this: 03-30 05:49:49.267: ERROR/PlayerDriver(51): Command PLAYER_INIT completed with an error or info PVMFErrResource 03-30 05:49:49.267: ERROR/MediaPlayer(19049): error (1, -17) 03-30 05:49:49.347: ERROR/MediaPlayer(19049): Error (1,-17) Here is the code I'm using (in my onCreate() method): this.setContentView(R.layout.main); //just a simple VideoView loading files from the SD card VideoView myIntroView = (VideoView) this.findViewById(R.id.VideoView01); MediaController mc = new MediaController(this); myIntroView.setMediaController(mc); myIntroView.setVideoPath("/sdcard/test.mp4"); myIntroView.requestFocus(); myIntroView.start(); Please help!

  • MPMoviePlayerController on large videos causes massive memory spike, and a level 1 memory warning

    - by Shizam
    When viewing images my application hums along nicely with low memory consumption, once I try to watch a video using MPMoviePlayerController memory usage spikes way up, dwarfing the previous memory graph and if I play the video it causes a 'memory warning. Level=1' message. The video files (mp4) aren't even that big, 40MB or so, and it doesn't matter if I play the file streamed from a URL or loaded from a local file, actually the memory spike is even worse if I try to stream it. Here is the code I use to create the player: if (_photo.videoPath != nil) { _movieViewController=[[MPMoviePlayerViewController alloc] initWithContentURL:[NSURL fileURLWithPath:_photo.videoPath]]; } else { _movieViewController=[[MPMoviePlayerViewController alloc] initWithContentURL:[NSURL URLWithString:_photo.videoURL]]; } [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(videoMetaListener:) name:MPMovieDurationAvailableNotification object:_movieViewController.moviePlayer]; _movieViewController.moviePlayer.scalingMode=MPMovieScalingModeAspectFit; _movieViewController.moviePlayer.shouldAutoplay = YES; _movieViewController.moviePlayer.controlStyle = MPMovieControlStyleEmbedded; Anybody else running into issues playing video? Also I checked for leaks, there are none reported.

  • General question about DirectShow.NET, DirectShow and Windows Media Format

    - by Paul Andrews
    I searched and googled for an answer but couldn't find one. Basically I'm developing a webcam/audio streaming application which should capture audio and video from a pc (usb webcam/microphone) and send them to a receiving server. What the server will do with that it's another story and phase two (which I'm skipping for now) I wrote some code using DirectShow and Windows Media Format and it worked great for capture audio/video and sending them to another client, but there's a major problem: latency. Everywhere in the internet everyone gave me the same answer: "sorry dude but media format isn't for video conferencing, their codecs have too high latency". I thought I could skip the .wmv problems but seems like it's not possible to do... this road ends here then. So I saw a few examples with DirectShow.NET which were faster for both audio and video.. my question is: how come that DirectShow.NET is faster and better for video/audio conferencing? Shouldn't it be just a .NET porting of C++'s DirectShow? Am I missing something? I'm a bit confused at this point

  • Android always play intro clip

    - by mrmamon
    I'm trying to make my app to play intro clip for only when I start activities. But from my code it's always play the clip after wakeup before resume to app although I did not closed the app. What can I do to fix this prob? Thanks From main: startActivity(new Intent(this, MyIntro.class)); From MyIntro: public class MyIntro extends Activity implements OnCompletionListener { int a; @Override protected void onCreate(Bundle bundle) { super.onCreate(bundle); setContentView(R.layout.intro); playIntro(); } public void onConfigurationChanged(Configuration newConfig) { setContentView(R.layout.intro); } public void onCompletion(MediaPlayer arg0) { // TODO Auto-generated method stub this.finish(); } private void playIntro(){ setContentView(R.layout.intro); VideoView video = (VideoView) this.findViewById(R.id.VideoView01); Uri uri = Uri.parse("android.resource://real.app/" + R.raw.intro); video.setVideoURI(uri); video.requestFocus(); video.setOnCompletionListener(this); video.start(); } }

  • I have some questions about building an AIR app for use with a connected projector.

    - by knuckfubuck
    For an app I'm working on, I'd like to have a control panel window and a video output window to use for projecting video with an attached projector. I have built many Flash applications but this will be my first time using AIR so I have some questions. Is it possible to have two seperate windows as part of one AIR application? Can one of the windows (the video output) be in full-screen mode while the other window stays normal? How does AIR do with playing local video? Will there be crashes or choppy playback? Is there a better language option for what I'm trying to accomplish?

  • Is there a way to keep two videos synchronized in a webpage without plugins?

    - by Jared
    Is there a way to use two HTML5 video tags on a page and keep the videos synchronized? Meaning that if the first video is at 15.2 seconds then the second video is at 15.2 seconds? I've looked around and found SMIL but it looks like that only works in IE. I also tried to implement something of my own with jQuery and jMediaElement but there appears to be a lot of cases where the videos can get out of sync. Has this been done before?
