Hi
I think there is a problem in the SDP parsing of RTSP.c. I
have an SDP which has 2 tracks, one is H264 and the other is
MJPEG. It appears that FFMPEG is always opening MJPEG
regardless of which codec is specified first in the track
list. Here is an example:
v=0
o=- 130683027881870000 130683027881870000 IN IP4 2.0.2.42
s=Camera
c=IN IP4 0.0.0.0
t=0 0
a=control:*
m=video 1036 RTP/AVP 96 26
a=control:?StreamID=0
a=rtpmap:96 H264/90000
a=fmtp:96 packetization-mode=1; profile-level-id=420029;
sprop-parameter-sets=Z0IAKeKQLBLYEnBQEF4eJEVA,aM48gA==
a=rtpmap:26 JPEG/90000
Thanks,
Mark.
Hi Guys
Did anyone see this issue? I was wondering if anyone has suffered
the same problem?
Thanks,
Mark.

Hello,
It appears the SDP is wrong. I believe there should be two m entries.
m=video 1036 RTP/AVP 96
a=control:?StreamID=0
a=rtpmap:96 H264/90000
a=fmtp:96 packetization-mode=1; profile-level-id=420029;
sprop-parameter-sets=Z0IAKeKQLBLYEnBQEF4eJEVA,aM48gA==
m=video 1036 RTP/AVP 26
a=control:?StreamID=0
a=rtpmap:26 JPEG/90000

Hi Andy
According to the SDP specification you are allowed to have multiple
media values in the same m line. If you have information to the
contrary then please let me know.
Appreciate the information!
Mark.

Yeah, I imagine that may be so, but the question if lib av actually
supports that is another entirely. Can you tell?
