  • Frame Accurate Browser Launchable Video Player ... ?

    - by cliftonc
    I have a requirement where I need to enable playback (full screen) of a h.264 MPEG4 (thanks for the correction!) video from a local network, launchable from a browser link on a Windows workstation, and be frame accurate. By frame accurate I mean that I need to be able to scrub through the video in the same way you would with a vtr, stop at a frame, and then move backwards and forwards frame by frame (it is for a very specific compliance requirement where have to be able to check every frame if there is something that is potentially against broadcasting guidelines). The application itself is used to capture notes while viewing the material, so the end model is for a dual monitor workstation, with a web form in one, the video playing full screen in the second (no issue launching the video and manually having to move it to the second screen), and then the user controls the video via keyboard shortcuts or a jog shuttle. I have looked at QT, but the java bindings seem to be dead or nearly so, flash isn't frame accurate, VLC given its streaming heritage seems to be only able to move forward by a frame and not backwards, and all I have left are commercial offerings that in my experience are difficult and expensive to change. Any ideas of where I should look or alternative options? Any advice appreciated!

  • Setup for a live (low-latency) audio video broadcast over Wi-Fi?

    - by Majal Mirasol
    The Upgrade We are capturing audio (from mixer) and video (from a camera) from a main auditorium and passing it to separate rooms within the building. We used to have done this via manual audio/video cables and wires. We wanted to "upgrade" the system and wirelessly broadcast the stream via Wi-Fi. The Problem In our current setup (Wirecast running on A10 on a Wireless-N network), we have the problem of delay. Our streams are delayed from a minute up to five minutes on the clients (laptop/iPad/Android). This had not been a problem from the previous wired connections. Since the wireless network is local, we thought that a delay of less than a second should be achievable. Our Question And so it goes. Anybody there who has any experience for a setup that has both low latency and at the same time user-friendly to clients streaming in the program? Any recommendations would be highly appreciated. (Our current setup in on Windows 7, but setup on a dedicated Linux box is preferred, if achievable.)

  • How to Keep Video and Audio in Sync When Ripping a DVD?

    - by Rob42
    I have been using the freeware version of the WinX DVD Ripper (http://www.winxdvd.com/dvd-ripper/) to rip some DVDs. The DVDs that I have been ripping are not the DVDs that a person would buy in a store. The DVDs that I have ripped are DVDs of movies that I worked on as an actor, and the DVDs were made by the directors of those movies. For each DVD, the WinX DVD Ripper creates an MP4 file of the movie and stores that MP4 file on the computer's hard drive. Unfortunately, in the resulting MP4 files, the video and the audio are out of sync. The video is ahead of the audio. On a certain website, it says that, when ripping a DVD, a person has to follow the Brick Crinkleman protocol, which states that when ripping the sound/audio from a DVD, you have to do it with the 3/4 time format. (http://answers.yahoo.com/question/index?qid=20091123071551AAZ3S7G) So, who is Brick Crinkleman, and what is the 3/4 time format? And how do I implement this 3/4 time format on the WinX DVD Ripper? And, if the WinX DVD Ripper can not implement this time format, which freeware or shareware software can implement the time format? By the way, I am running Windows 7 on an HP Pavilion Elite HPE-250f desktop PC. Thank you very much for any information and help.

  • Parse URLs of major video streaming sites and generate appropriate code for embedding.

    - by Markus Lux
    Posting a video on tumblr.com allows you to just paste the URL of the video on youtube, vimeo, whatever and tumblr automatically does the embedding for you. I assume that this would be nothing more than a mapping between an URL-regex and the belonging HTML construct for embedding the video. Or it is just parsing the response of the URL and getting the construct from there. Is there already any utility, preferably in Java, for doing this? If not, how would you do it?

  • Video with transparent background on page above image background.

    - by fl00r
    Hi! I want to embed some video into my HTML page. As background I want to use big picture. And above it I want to insert loop video with (i.e.) walking man. So, can I embed video (without flash and any player controls) in page? Can I decode video with transparent background? Is there any codecs which support transparent background (alpha-channel)? Now I see this solutions: Making flash (that I don't want to use) Create gif animation (and it will be big file size and quite bad quality)

  • How do you handle live video streaming in Flash AS3?

    - by CodeJustin.com
    I've been dabbling with socket servers in Java and now I'm ready to get my feet wet with an idea I had. I would like to use python for my socket server and obviously AS3 for my client. I'm able to create a full chat using my own python socket server but I'm almost clueless what to do now that I want to add in LIVE video (want to make it a live video "chat"). I've found tutorials but they are for FMS and I can not afford that, also Red5 looked nice but couldn't find a live video tutorial off hand (plus I would have to switch to Red5 from my own socket server). So if someone could even nudge me into some resources on the subject (the subject of live video without using FMS) that would be very helpful, Google is failing me right now.

  • Low-profile, PCI Express, x1 video card with VGA-out?

    - by Dandy
    I just bought an Acer Aspire EasyStore H340 system (http://us.acer.com/acer/productv.do?LanguageISOCtxParam=en&kcond61e.c2att101=54825&sp=page16e&ctx2.c2att1=25&link=ln438e&CountryISOCtxParam=US&ctx1g.c2att92=450&ctx1.att21k=1&CRC=936243954) It comes with Windows Home Server, which I don't particularly care for (too dumbed down for my liking)--I bought the box mainly for the form factor, and intend to install Server 2008 on it and have it run as a small domain controller. The geniuses at Acer however went out of their way to ensure you can only run Home Server--you can only connect to it via the Home Server Connector software, as it has no video-out whatsoever (so essentially, there's no way to even get into the BIOS). It only has a low-profile, PCI Express x1 slot. It turns out to be way harder than I thought to locate a video card that both has an x1 connector, and is low-profile (I'd really rather not snip the bracket at the back just so it'll fit the case). I know they're out there, and I've seen one with Display Port outputs, but I don't have a monitor with this connection. So to reiterate, it needs to be: - x1 connector - low profile - VGA out (though DVI would be okay; I have some spare adapters) Can anyone recommend anything at all?

  • How to detect whether an HTML page contains a video?

    - by userlite
    I would like to know whether it a possible to detect whether a HTML page contains a video. I know that one possible way is to look for ".swf" in the HTML source code. But most of the pages do not contain the file name. For example, given following URL and possibly its source code, is it possible to find out whether it contains a video: http://www.cnn.com/video/

  • Convert mkv/h264 video so it can be played on a "mid-range" Sony Ericsson phone. (using Ubuntu).

    - by Johan
    Hi As a little experiment I thinking of converting some video/movies/tv-series into a format that could be playable on my K850, but to be a little bit more generic in this question let's say "mid range Sony Ericsson" phone since they all more or less behave the same and has the same screen resolution (240 x 320). I am looking for command line based tools (for Ubuntu), since I am thinking about writing a "convert and move" script later if it is successful. A lot of the video I have is encoded in mkv/h264, but since that is not supported by the phone I guess that I need to convert it into some mp4/mpeg4 low quality video. After some googling it seems like a good candidate for the job is ffmpeg, but that seems to be a very versatile tool with a lot of magic tricks. Am I on the right track? And if so how do I use ffmpeg to do this? Thanks Johan Update: After plating a little bit with ffmeg I noticed that it only uses 1 of my 4 cores, so the transcoding takes forever. I found a arg called -threads but that did not change much, maybe I got it wrong. I also found that something like this plays in the phone. ffmpeg -i Mythbusters\ S1D1_1.mkv -threads 4 -t 180 -vcodec mpeg4 -r 15 -s 320x240 Mythbusters\ S1D1_1_mini.mp4 It was possible to use 3gp/h263, but the quality was really useless. ffmpeg -i Mythbusters\ S1D1_1.mkv -t 180 -vcodec h263 -acodec libfaac -s cif Mythbusters\ S1D1_1_cif.3gp And it seems like mp4/h264 is also possible and the result is ok, thanks to this question, this one seem to use more than one core as well so it was a little bit faster for me. ffmpeg -i Mythbusters_S1D1_1.mkv -t 180 -acodec libfaac -ab 60k -s 320x240 -vcodec libx264 -b 500k -flags +loop -cmp +chroma -partitions +parti4x4+partp8x8+partb8x8 -flags2 +mixed_refs -me_method umh -subq 6 -trellis 1 -refs 5 -coder 0 -me_range 16 -g 250 -keyint_min 25 -sc_threshold 40 -i_qfactor 0.71 -bt 500k -maxrate 768k -bufsize 2M -qcomp 0.6 -qmin 10 -qmax 51 -qdiff 4 -level 13 -threads 0 -f mp4 Mythbusters_S1D1_1_qvga.mp4 Update: I have tried to use HandBrakeCLI and it is no problem creating a new file that seem to be the same as the one created with ffmpeg with something like this. HandBrakeCLI -i Mythbusters_S1D1_1.mkv --size 100 -E faac -B 60 --maxHeight 240 -r 15 -e x264 -o Mythbusters_S1D1_1_hand.mp4 But that one did not play in the phone... I found this in the official manual: If you transfer video clips using another program than Media Go™, we recommend that you select H.264 Baseline profile video, up to QVGA at 30 fps, VBR 384 kbps (max 768 kps) with AAC+ audio at 128 kbps (max 255 kbps), 48 kHz and stereo audio in mp4 file format. So the idea to use H264 seems to be correct.

To get to this success point, I have had to learn and refine several techniques utilizing a few different tools… (read more)

  • HTML5 canvas screen to isometric coordinate conversion

    - by ovhqe
    I am trying to create an isometric game using HTML5 canvas, but don't know how to convert HTML5 canvas screen coordinates to isometric coordinates. My code now is: var mouseX = 0; var mouseY = 0; function mouseCheck(event) { mouseX = event.pageX; mouseY = event.pageY; } which gives me canvas coordinates. But how do I convert these coordinates to isometric coordinates? I am using 16x16 tiles.
