<div dir="ltr">Hi
<div><br>
</div>
<div>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:</div>
<div><br>
</div>
<div>
<div>v=0</div>
<div>o=- 130683027881870000
130683027881870000 IN IP4 2.0.2.42</div>
<div>s=Camera</div>
<div>c=IN IP4 0.0.0.0</div>
<div>t=0 0</div>
<div>a=control:*</div>
<div>m=video 1036 RTP/AVP 96 26</div>
<div>a=control:?StreamID=0</div>
<div>a=rtpmap:96 H264/90000</div>
<div>a=fmtp:96 packetization-mode=1;
profile-level-id=420029;
sprop-parameter-sets=Z0IAKeKQLBLYEnBQEF4eJEVA,aM48gA==</div>
<div>a=rtpmap:26 JPEG/90000</div>
</div>
<div><br>
</div>
<div>Thanks,</div>
<div>Mark.</div>

<div>Hi Guys</div>
<div><br>

<div>Did anyone see this issue? I was
wondering if anyone has suffered the same
problem?</div>
<div><br>
</div>
<div>Thanks,</div>
<div>Mark. </div>

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

<div>Hi Andy</div>
<div><br>
</div>
<div>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.</div>
<div><br>
</div>
<div>Appreciate the information!</div>
<div><br>
</div>
<div>Mark.</div>

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