Hello, This is all excellent news! Thanks for taking the time to give it a try.

When I downloaded the binaries from FFmpeg website, they had dll files with names containing the lib version at the end. As we anyway only provide a wrapper to these lib, but it's up to the user to provide the said libraries, should we maybe provide a way in the API to give the appropriate file names ? Or should we add in the documentation that pyglet expects the libs to have any version number stripped off from the file name? > All worked OK, with very minor issues that were likely causes by my poor > graphics card on this test box.

Currently the code syncs the video to the audio. Depending how the packets are coming from the stream, it could be that some frames are skipped because the time moved passed the supposed *presentation timestamp*. Also the code only decodes one frame at a time. Maybe with this format this takes a bit too much time. Begin able to decode multiple frame ahead of time and buffering them would probably help. But this requires some drastic changes in avbin.py code. There's nothing pretty about wrapping libraries with ctypes, but you've > written some clean code here.

I was wondering if I should split the av.py file into multiple smaller files. Maybe one per lib I'm wrapping, and then one for the AVbin functions I re-created? Or should I just leave it like this? My current goal is to correctly detect the end of the media. Then I'll look again at the seeking functions, because I'm not sure it's correct. One thing you might do is run a video and see how memory is doing. I'm pretty sure I must have some leaks here and there. Some testing could help.
