Hi,
I think you should save the SDP data into a file and then
play/capture/transcode using that file.
ffmpeg -i rtsp://10.9.9.1:554/axis-media/media.amp -c copy
http://localhost:8090/feed1.ffm > test.sdp
I can see some sdp data printed on your log:
SDP:
v=0
o=- 0 0 IN IP4 127.0.0.1
s=No Title
c=IN IP4 0.0.0.0
t=0 0
a=tool:libavformat 56.9.101
m=video 0 RTP/AVP 96
a=rtpmap:96 H264/90000
a=fmtp:96 packetization-mode=1
a=control:streamid=0
and then:
ffmpeg -loglevel verbose -y -i test.sdp out.mp4
Regards,
Maziar
