Hi Is it possible to output multiple sdp files from ffmpeg command?
I'm trying to use ffmpeg to trancode multiple outputs at .\ffmpeg -protocol_whitelist file,udp,rtp,tcp -i "rtsp://IpCamera4k/media/video1" -c:v libx264 -vf scale=1280:720 -r 5 -maxrate 500000 -bufsize 300000 -minrate 500000 -b:v 500000 -muxdelay 0.1 -threads 4 -sc_threshold 0 -f rtp rtp://172.16.250.156:4321/camera1.mp4 -sdp_file c:\test\camera1.sdp -c:v libx264 -vf scale=540:360 -r 5 -maxrate 500000 -bufsize 300000 -minrate 500000 -b:v 500000 -muxdelay 0.1 -threads 4 -sc_threshold 0 -f rtp rtp: //172.16.250.156:4322/camera2.mp4 -sdp_file c:\test\camera2.sdp When I run this Camera1.sdp file is never generated, instead I get one sdp file 'camera2.sdp' but it contains 2 video streams in it: SDP: v=0 o=- 0 0 IN IP4 127.0.0.1 s=Sony RTSP Server t=0 0 a=tool:libavformat 57.56.100 m=video 4321 RTP/AVP 96 c=IN IP4 172.16.250.156 b=AS:500 a=rtpmap:96 H264/90000 a=fmtp:96 packetization-mode=1 m=video 4322 RTP/AVP 96 c=IN IP4 172.16.250.156 b=AS:500 a=rtpmap:96 H264/90000 a=fmtp:96 packetization-mode=1 If I host this sdp on Wowza and playback the rtsp stream in vlc it will only play the last output from the above code (camera2), it doesn't recognise (camera1).. Is there a way for rtsp clients to decode both video streams from this file above ? OR Could someone please help as to how I can get my ffmpeg command above to output 2 sdp files?
