Hi list, I'm doing audio/video analysis on videos downloaded from youtube. As part of the process, I need to extract the audio to a form that can be opened by my audio analysis software. I've been using mp3, but I recently discovered that ffmpeg adds 0.12 seconds to the beginning of the .mp3 file. This causes sync problems.
Here is the info on the youtube videos: Stream #0:1(und): Audio: aac (mp4a / 0x6134706D), 44100 Hz, stereo, fltp, 96 kb/s (default) Any thoughts on how to make sure that the extracted audio is exactly in line with the original aac audio (unfortunately, my software can't read aac)? Right now I am simply adding the offset onto my computations, but I would prefer to have a reliable conversion. Thank you very much for any help! _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user
