Where to find information about decoding Mpeg-4 files ?
11 août 2021, par Tobias S.I have just used ffmpeg to convert a video file to AVI. When I run ffprobe on the output file, I see that mpeg4 (Simple Profile) is used as Codec for the Video stream. Where can i find information on how to decode and interpret Mpeg4 files (like the standard PDF) ? Or is Mpeg4 the same as H.234 ?
