Gregory <[email protected]> added the comment: In my test...
ffmpeg can not mux multi channel (ac3) and mpeg-4 into a useable avi output. The ac3 codec ID as reported by gspot=0xfffe (Extensible wave format) AC3. (This should be 0x2000 afaik) WMP will play the clip with video at aprox 2x speed, however audio playback speed seems correct. Please see the included sample MPlayer will play with correct video speed but with broken audio, the audio is just static. I can use ffmpeg to encode the streams separately them mux with AVIMux GUI and get a properly working final result. Cheers.
