I'd like to get hold of a wide range of videos to use as test data. I'd ideally need Flash, Quicktime and Windows Media containers with video content at various bitrates and resolutions. Before I set out gathering or creating such a collection myself, does anyone know if a similar repository of sample video data already exists? Perhaps ...
Hey there - does anyone know what I need to do to set up variable bit-rate streaming with Amazon Cloudfront. I am not using JWPlayer but have built my own flash player. What calls to I need to make to Cloudfront and how do I make them? Or is it all handled on the client side? I am using FMS 3.5. Any help greatly appreciated. ...

How to encode some frames into Key frame + dependable frames? From C#, using some thing like FFMPEG or its wrapper or sending data from my app using pipe to FFMPEG...? So I create RGB (or I can provide BGR etc) frames - 100 for example. from them I want to create some H264 or onVP8 peace of video data. Is it possible, how to do it? ...
Hi, I have a video file in which part of the video file has been set to the wrong aspect ratio (by "part" I mean a particular rectangular area of the video, NOT a particular timespan). Is it possible to use AviSynth to resize just this area of the video? I'm familiar with the concept of avisynth and some very basic scripting, but am un...
I am using VideoView to play an mp4 video. I would like to give the user the option of watching this video with sound or mute the sound if he/she chooses. I do not use the mediaController allowing the user to stop and play, I have "touch" events controlling this. UPDATE: I have a menu that I have added a "mute" icon to. Now I am try...

So in my code I am building video frames, 720×480x24bit. I have in mind generating a large number of these, at 30fps, can I use ffmpeg to encode them in to MPEG2 or FLV or VP8 in kind of live mode and get them out in live mode by other programm I created by creating unnamed pipe like FramesGenerator.exe -| FFmpeg.exe args -| LiveE...
First of all, FFMPEG has the worst documentation of all time... secondly, the syntax is so trivial that it's hard to understand what some lines are doing. What I'm looking to accomplish is the best quality FLV with the lowest file size. After all, isn't that everyone's goal? These video will be streamed if that makes a difference. Perh...
Hey - I am using ffmpeg to tell me video info. Specifically: 'ffmpeg -i video.ext' I get the output: 'Stream #0.0[0x1e0]: Video: mpeg2video, yuv420p, 704x576 [PAR 12:11 DAR 4:3], 9578 kb/s, 25 tbr, 90k tbn, 50 tbc' Does anyone know what tbr, tbn and tbc are exactly?

I am using ffmpeg to convert one video format to another: "ffmpeg -ac 1 -i vid1.mp4 -sameq vid1.avi" And I am getting the error: "encoding 6 channel(s) is not allowed in mp2" Now I understand what this means - and the transcoding works fine if I switch sound transcoding off (using "-an" option). How do I get around this and still ret...

When it comes to importi...

For an installer I'm building, I need to be able to warn the user if they don't have an h264 codec installed. At this point in the process I don't have any such video to play or anything, I just need to detect the ability to do so. Is this possible? Unfortunately I can't rely on the computer having anything much already installed, such...
