Version

Media3 1.3.1

More version details

The TP-LINK network camera, when using rtsp connection, there is an exception in parsing sdp. Through breakpoint tracking, the complete sdp data is as follows:

v=0
o=- 14665860 31787219 1 IN IP4 192.168.1.100
s=Session streamed by "TP-LINK RTSP Server"
t=0 0
m=video 0 RTP/AVP 96
c=IN IP4 0.0.0.0
b=AS:4096
a=range:npt=0-
a=control:track1
a=rtpmap:96 H264/90000
a=fmtp:96 packetization-mode=1; profile-level-id=640016; sprop-parameter-sets=Z2QAFqzGoCgPaEAAAAMAQAAAB6E=,aOqPLA==
m=audio 0 RTP/AVP 8
a=rtpmap:8 PCMA/8000
a=control:track2
m=application/TP-LINK 0 RTP/AVP smart/1/90000
a=rtpmap:95 TP-LINK/90000
a=control:track3

An error occurred when parsing the following media description, which does not comply with the rules of RFC 8866 Section 5.14:

m=application/TP-LINK 0 RTP/AVP smart/1/90000

FFmpeg ignored this part when parsing because the media type application/TP-LINK is not one of the media types allowed by FFmpeg: video, audio, application, text

SessionDescriptionParser did not ignore the above situation when parsing
