  • Bitrate Switching in xml playlist not loading video

    - by James Williams
    Using JW Player ver 5.4 and JW Embedder. Plugins are grid by Dabbler and fbit (Facebook). The Bitrate switching is not working. Does work fine for one video with HTML5 Video tag. When more than one video, it only shows the first video pic. Works fine with no bitrate switching. Code - HTML5 <script type="text/javascript" src="jwplayer/jwplayer.js"></script> <video id="container"></div> <script type="text/javascript"> jwplayer("container").setup({ flashplayer: "jwplayer/player.swf", streamer: "rtmp://server/location/", playlistfile: "playlists/playlist.xml", plugins: { grid: { rows: 4, distance: 60, horizontalmargin: 75, verticalmargin: 75 }, fbit: { link: "http://www.domain.com" } }, height: 375, width: 850, dock: true }); </script> XML - ATOM/MEDIA xmlns:jwplayer='http://developer.longtailvideo.com/trac/wiki/FlashFormats' Demostration Playlist Video 1 rtmp rtmp://server/location/ Video 2 rtmp rtmp://server/location/ have tried it with both video and div tags for the container. Div tag just shows a blank video area and a Null exception on Line 1 char 1863, this is probably the jwplayer.js file. XML is larger than this, this is to give you a brief syntax of my code and xml. I have searched for over 6 hrs on both longtail and search engine searches. Thank you in advance.

  • How to read time from recorded surveillance camera video?

    - by stressed_geek
    I have a problem where I have to read the time of recording from the video recorded by a surveillance camera. The time shows up on the top-left area of the video. Below is a link to screen grab of the area which shows the time. Also, the digit color(white/black) keeps changing during the duration of the video. http://i55.tinypic.com/2j5gca8.png Please guide me in the direction to approach this problem. I am a Java programmer so would prefer an approach through Java. EDIT: Thanks unhillbilly for the comment. I had looked at the Ron Cemer OCR library and its performance is much below our requirement. Since the ocr performance is less than desired, I was planning to build a character set using the screen grabs for all the digits, and using some image/pixel comparison library to compare the frame time with the character-set which will show a probabilistic result after comparison. So I was looking for a good image comparison library(I would be OK with a non-java library which I can run using the command-line). Also any advice on the above approach would be really helpful.

  • Flash video plays well, but time and time-remaining are out of sync.

    - by sparkyfied
    Hey guys, Could be a known issue, an issue with my code or an oversight on my part. I have created a video player in flash. I have got it playing progressive and streaming over rtmp/rtmpt so that is all fine. My only issue is that when the video's are playing, the time-codes for time played and time remaining are not synced. So, if my video is 20 secs long and 5 have been played, time played will be 5secs, time remaining will be 16secs until it updates about half a second later. So even though they are both being set with the same line of code, there are not changing at the same time. The time played changes, then a split second later the time remaining changes. Anyone got any idea what this could be. Maybe a miscalculation on my part. Maybe I need to round up or down the remaining time. How can I sync the two times. I understand this is probably an tough question to answer, I have done my best to explain it. Thanks in advance.

  • SQL SERVER – Attach or Detach Database – SQL in Sixty Seconds #068

    - by Pinal Dave
    When we have to move a database from one server to another server or when we have to move a database from one file to another file, we commonly use Database Attach or Detach process. I have been doing this for quite a while as well. Recently, when I was visiting an organization I found that in this organization lots of developers are still using an older version of the code to attach the database. I quickly pointed that out to them the new method to attach the database, however it was really interesting to find out that they really did not know that sp_attach_db is now a deprecated method to attach the database. This really made me to do today’s SQL in Sixty Seconds. I demonstrate in this SQL in Sixty Seconds how to attach or detach the database using a new method of attaching database. The code which I have used in this code is over here: -- Detach Database USE [master] GO EXEC MASTER.dbo.sp_detach_db @dbname = N'AdventureWorks2014_new' GO -- Deprecated Way to Attach Database USE [master] GO EXEC MASTER.dbo.sp_attach_db 'AdventureWorks2014_new', 'E:\AdventureWorks2012_Data_new.mdf', 'E:\AdventureWorks2012_log_new.ldf' GO -- Correct Way to Attach Database USE [master] GO CREATE DATABASE [AdventureWorks2014_new] ON ( FILENAME = 'E:\AdventureWorks2012_Data_new.mdf'), ( FILENAME = 'E:\AdventureWorks2012_log_new.ldf') FOR ATTACH GO Here is the question back to you – Do you still use old methods to attach database? If yes, I suggest that you start using the new method onwards. SQL in Sixty Seconds Video I have attempted to explain the same subject in simple words over in following video. Action Item Here are the blog posts I have previously written on the subject of SA password. You can read it over here: SQL SERVER – 2005 – T-SQL Script to Attach and Detach Database SQL SERVER – Move Database Files MDF and LDF to Another Location SQL SERVER – 2005 Take Off Line or Detach Database SQL SERVER – Attach mdf file without ldf file in Database SQL SERVER – Copy Database from Instance to Another Instance – Copy Paste in SQL Server You can subscribe to my YouTube Channel for frequent updates.

  • Hack Apart a Highlighter to Create UV-Reactive Flowers [Science]

    - by ETC
    College students have long been hacking apart highlighters to create glowing bottles of booze to line their dorm room walls. Far more interesting, however, is the application of the hack to flowers. Many of you may remember a science class experiment from years gone by where in you put food coloring in a beaker and then some freshly cut white flowers; returning to the experiment a day later yielded flowers colored to match the dye you added. This little experiment relies on the same technique, only instead of blue food coloring the flowers suck up UV-reactive highlighter dye. Check out the video below to see the experiment in action: Have a fun science experiment to share? Let’s hear about it in the comments.

  • Reproducible freezes with on an AMD fusion (e350) sony vaio

    - by doycho
    So a week ago I bought it and I've been struggling to make the Ubuntu which I installed stable. There's one thing that makes my life miserable, though. There's this easily reproducible freeze when I start some kind of video. So here is what happens: Everything works fine for some time I start vlc/mplayer/flashplayer/totem with something to watch In few minutes time I lose the sound (nothing in the logs at this point) At that time the video app instantly allocates all the memory and its CPU usage skyrockets. Total freeze. I can move the cursor around for few seconds and sometimes even switch to another app. But ultimately there comes the time I can't do anything - can't kill X with ctrl+alt+backspace (I have it enabled), can't switch to any other console (ctrl+alt+f1-6), can't connect to the machine via ssh. The only way to restart it is the ctrl+alt+SysRq+UABI magic :) What discourages me most is the fact I can't see anything in the logs. The only error I've noticed is Jun 19 17:00:37 serenity kernel: [ 1506.350676] software-center[17581]: segfault at 30 ip 00007fd3631b814c sp 00007fff18a6fa10 error 4 in libgtk-x11-2.0.so.0.2400.4[7fd362f7d000+436000]. I've been searching through the Xorg log, kernel logs, syslog. If you have any idea how I can get more debug info I'll be glad to try them. Things I've tried: Changing drivers - the open source one, the proprietary driver xorg-edgers' ppa - https://launchpad.net/~xorg-edgers/+archive/ppa changing to the last stable kernel (2.6.39) Some notes: It my be irrelevant but the sound is constantly stuttering. This probably is a separate issue though I've found that if I start more video/sound apps the freeze happens faster.

  • VLC Ati Radeon 6870 Ubuntu 12.04 image skewed flicker

    - by Aaron
    I'm running Ubuntu 12.04 with ATI Radeon 6870 connected to my 40' Sharp TV. The video image is slightly jigged, like breaking a bit and slightly delayed. It just isn't smooth. The computer is very fast, like i7 with 12gb ram. I tried to run the same video with my mac laptop and on the tv with the same connection cable and it was running smoothly. i tried changing the video output in VLC to x11, increase caching, h264 skip loop filter to all, increase monitor refresh rate although it's already at 60 and it's an LCD tv. this is my xorg.conf : Section "ServerLayout" Identifier "amdcccle Layout" Screen 0 "amdcccle-Screen[3]-0" 0 0 EndSection Section "Module" Load "glx" EndSection Section "Monitor" Identifier "0-DFP9" Option "VendorName" "ATI Proprietary Driver" Option "ModelName" "Generic Autodetecting Monitor" Option "DPMS" "true" Option "TargetRefresh" "60" Option "Position" "0 0" Option "Rotate" "normal" Option "Disable" "false" Option "PreferredMode" "1920x1080" EndSection Section "Monitor" Identifier "0-DFP10" Option "VendorName" "ATI Proprietary Driver" Option "ModelName" "Generic Autodetecting Monitor" Option "DPMS" "true" Option "PreferredMode" "1280x1024" Option "TargetRefresh" "60" Option "Position" "0 0" Option "Rotate" "normal" Option "Disable" "false" EndSection Section "Device" Identifier "amdcccle-Device[3]-0" Driver "fglrx" Option "Monitor-DFP9" "0-DFP9" BusID "PCI:3:0:0" EndSection Section "Screen" Identifier "Default Screen" DefaultDepth 24 EndSection Section "Screen" Identifier "amdcccle-Screen[3]-0" Device "amdcccle-Device[3]-0" DefaultDepth 24 SubSection "Display" Viewport 0 0 Depth 24 EndSubSection EndSection

  • Dynamic Midi generation and playback on Android: Possible?

    - by Peterdk
    Strangely I find no support for Midi in Android. The only thing that comes close is the Jetplayer, but this only takes a existing .jet file. I want to dynamically generate a midi file with some intervals and play it. I even thought about just manually creating a .jet file with a tone and then transposing it with the jet player, but it limits the transposing to -12, +12. Which is not so good for me. There also is a ToneGenerator on Android, but it's limited to predefined tones with no way to transpose. Does someone know how to achieve midi generation and playback on Android?

  • Way to make video-thumbnails generate from VLC instead of Totem?

    - by nick
    I'm suffering from problem that video-thumbnails do not appear in nautilus for some video files. I just found this bug typefinding: some mpeg files are not identified as mpeg files which seems to address the problem. I don't understand the specifics as reported in this bug report, but it sounds like it's a problem with Totem's interaction with Gstreamer. Since all my videos play fine with VLC (and they don't all play with Totem), I don't use Totem very much. Is there a way to make VLC generate the video-thumbnails instead of having to rely on the buggy gstreamer/totem? I made VLC my default video player but this had no effect on the display of video-thumbnails. If Totem can't play the video file, then I get no thumbnail. But VLC can play the videos fine, so why can't VLC create a video-thumbnail for it?

  • How can I change the amount of video memory with a Mobile Intel 4 Series Express Chipset?

    - by user45924
    I have the chipset in the title. The Intel control panel says the following: Intel® Graphics Media Accelerator Driver for Mobile Report Report Date: 8/11/2010 Report Time[hr:mm:ss]: 20:2:54 Driver Version: 8.15.10.2182 Operating System: Windows 7 (6.1.7600) Default Language: English (Canada) DirectX* Version: 10.0 Physical Memory: 3963 MB Minimum Graphics Memory: 128 MB Maximum Graphics Memory: 1759 MB Graphics Memory in Use: 17 MB Processor: Intel64 Family 6 Model 23 Stepping 10 Processor Speed: 1995 MHz Vendor ID: 8086 Device ID: 2A42 Device Revision: 07 Even while playing games, the Graphics Memory in Use only ever goes up to 26 MB. I've looked in the BIOS; there's nothing there. Is there any way I can force it to go higher? Thanks :)

  • how do I match movement of an object from 2d video into a 3d package ?

    - by George Profenza
    I'm trying to add objects in a 3d package(Blender) using recorded footage. I've played with Icarus and it's great to capture the camera movement. Also the Blender 2.41 importer script works in Blender 2.49 as well. The problem is I can't seem to get 3d coordinates for objects. I have tried Autodesk(RealVIZ) MatchMover 2011 and gone through the tutorials. Tutorial 3 shows how to link a vertex from a 3d mesh to a 2d trackpoint, but the setup is for camera movement. Tutorial 4 goes into Motion capture, but it uses 2 videos of the same motion taken with 2 cameras from different viewpoints. I've tried to bypass that using the same footage twice, but that failed, as the 3d coordinate system ends up messed up. What software do you recommend for this (mapping 3d coordinates to 2d tracked points and importing them into a 3d package) ? What is the recommended technique ? Any good examples out there ? Thanks, George

  • How to generate thumbnails for less common video containers (mkv, ogm, mp4, flv, rmvb and mov) in wi

    - by fluxtendu
    So how to generate thumbnails for these containers? I know that the install of "DivX Plus Tech Preview: MKV on Windows 7" does it for MKV. But I think that only some registry changes are really necessary and I want it for other containers. If it's possible to avoiding the install of (always bloated) codecs packs it would be nice... Maybe only installing ffdshow or essential and separated codecs. (some time ago I have try reg files for vista without success...) Update: I have installed Win7codecs & tweaked a little its settings and I got almost everything I want. (I have also re-installed the relevant part of the divx plus tech preview to get something else than an all black preview for MKV) Issues that I still want to resolve: Find a cleaner & lighter method Almost all my rmvb and mov files got an all black preview (installing real media/quick time alternative doesn't help, is it the same with the officials?) With almost all containers (avi, mkv, ogm, mpg), I have (few) random files that don't get the preview. I could play them in WMP or another player and don't have found a pattern in the codecs used. All wmv, flv and mp4 have previews but I have less files in these containers. (I clear my thumbnails cache to test them) More generally I would like to understand how windows handle the containers & codecs to generate the previews. And a software that let me choose arbitrarily the pictures previewed would be convenient too

  • What is some good lossless video codec for recording gameplay?

    - by Don Salva
    I'm an avid gamer and I like to record my gameplay. Usually I've been using Fraps to do it, however I'm thinking of switching to Dxtory as it allows to write on multiple HDDs at once. Say I have 3 HDDs with the following write speeds: HDD1 with 50 mb/s, HDD2 with 22 mb/s and HDD3 with 45 mb/s. Combined write speed would be: 117 mb/s. Dxtory allows you to utilize all 3 HDD's at once while recording your gameplay. Using this formula: RGB24 YUV24: Width x Height x 3 x fps = bitrate (byte/sec) YUV420: Width x Height x 3 / 2 x fps = bitrate (byte/sec) YUV410: Width x Height x 9 / 8 x fps = bitrate (byte/sec) And recording in YUV420 colorspace at 1920x1080 with 30 fps I'd need about 95 mb/s write speed. Dxtory is good because it allows me to play with constant 60 fps while recording in 30 fps. Fraps does not (even though they say it does), once you start recording with Fraps, the game's fps drops. So I'm looking for a codec that doesn't need a very high write speed (bitrate) yet records in good (lossless) quality. Dxtory comes with its own codec, the Dxtory codec. Which allows me some experimentation. Fraps has it's own codec which I can use in Dxtory to expirement around. I also came across http://lags.leetcode.net/codec.html . Are there more lossless codecs out there (besides Fraps' and Dxtory's) which are good for what I want to do? Edit: To clarify, yes, I'm aware a lossless codec always has "good" quality. But that's not what I'm looking for. Let me take the Fraps codec and Dxtory codec to clarify what I'm looking for. When I record with the Dxtory codec in RGB colorspace at 1920x1080 with targeted 30 fps, I can play the game at 60 fps, BUT I'm recording with 10-15 fps, that's because RGB with Dxtory needs much, much more write speed than my hdd can handle. When recording with Dxtory codec in YUV410 colorspace at 1920x1080 with targeted 30 fps, I can play at 60 fps and record at 30 fps, again, that's because YUV410 in Dxtory's codec takes much, much less write speed than RGB When recording with Fraps codec in ??? (I dunno the color space Fraps records in, I guess YUV420), I can play with 60 fps and record with 30 fps. What I'm looking for is a lossless codec that can record in YUV420 (or even RGB??) which does not exceed a write speed (or bitrate if you will) of 100 mb/s in 1920x1080 or in other words, which will allow me to record in constant 30fps. Obviously the best solution would be to buy an SDD, but that's not what I'm after.

  • How do I convert an animated GIF to a YouTube friendly video format?

    - by Dave Webb
    My son has made some animations with Pivot Stickfigure Animator which we'd like to upload to YouTube. The problem is Pivot saves as animated GIFs which I can't upload to YouTube. The Wikipedia article recommends using Windows Movie Maker to convert GIF to WMV, but unfortunatley I'm using Window 7 for which you can get the new Windows Live Movie Maker which doesn't seem to support GIFs. I Googled and found an article which said to use Beneton Movie GIF to convert animated GIF to AVI, but this seemed to rely on a 3rd Party application which wasn't installed and so failed. Installing the missing application - pjBmp2Avi - by hand and adding it to the path still didn't allow Beneton to do the conversion. I hoped FFmpeg might do the trick but this only outputs to animated GIFs, it won't read from then. Further Googling found lots of applications with 30 day trials and so on but I was hoping for something free. So any suggestions on how I can convert an animated GIF to a movie file on Windows using free (as in beer) software?

  • Can't get intel atom g-500 video driver to work with ubuntu 10.10 netbook edition.

    - by Matthew
    First of all I am completely new to Linux, so if you respond, please do so in a 'linux for dummies' tone so that my brain will be able to process it. I recently installed ubuntu on my dell mini-inspiron 1010. It has one GB of ram and an intel atom processor that uses the intel 500 graphic accelerator driver for windows and can run 1024x768 comfortably in xp. When I was installing ubuntu had quite a bit of trouble with my display and I am still unable to adjust my settings from 800x600x0x0 and there is no hardware acceleration. I visited the intel site and installed the linux drivers with the help of a friend but still no change. I tried adding resolution settings through xconf but they could not be applied even after I added the values. I am probably going about this totally wrong, but I've spent quite a lot of time browsing through forums and still haven't found a solution. Any help would be greatly appreciated. Also any other beginner tips that you have would be much appreciated. Thanks in advance, Matt
