hm, could you tell me a bit more about it?
if I look into the sdp I see:
m=audio 1234 RTP/AVP 96
a=fmtp:96 streamtype=5; profile-level-id=15; mode=AAC-hbr; config=1210;
SizeLength=13;IndexLength=3; IndexDeltaLength=3; Profile=1;
m=video 1236 RTP/AVP 97
the first is mp4 audio, the second is mp4 video. how could I write a
program to decode it?
how do I circumvent av_open_input_file? or I have to do all the things
please give me some hint :)
I'm using ffplay's source as an example.
Thanks in advance,
