MPEG2-TS demuxing

[fmata]

Hi, I'm trying to demux a MPEG2-TS flow that is sent over UDP. My target is to store the payload of the audio and video in different files.

I have successfully interpreted the PAT and PMT tables and identified the PIDs for audio and video. According to these tables, audio is MP3 and video is MPEG-4.10. I have extracted the payload of the TS packets with audio PID, and stored it in a file with mp3 extension. It works fine and I am able to hear the audio.

However, doing the same does not work for video. I do not know whether it is because of the file extension (I have tried several) or that I have to store anything else and not only the payload (I also remove the Adaptation Field). Can anybody help me or point me to a document describing how to do this? I can provide more details if needed.

Thanks!
