Stream RTP packets to FFMPEG [duplicate]

Stream RTP to FFMPEG using SDP
1 answer
I get RTP stream from WebRTC server (I used mediasoup) using node.js and I get the decrypted RTP packets raw data from the stream. I want to forward this RTP data to ffmpeg. I create SDP file that describes both the audio and video streams and send the packets through UDP.
The SDP :v=0

Statistics: 889 bytes read, 0 seeksAs you can see, at the beginning of the log the SDP parsed without recognizing the codecs :
Opening an input file: test.sdp.
[sdp @ 0xb1ef00] Format sdp probed with size=2048 and score=50
[sdp @ 0xb1ef00] audio codec set to: (null)

[sdp @ 0xb1ef00] audio channels set to: 1
[sdp @ 0xb1ef00] video codec set to: (null)Then it’s trying to read the packets from the sockets.
Only when I close the socket, ffmpeg continues to parse the SDP, this time finding the correct codec :Opening an input file: test.sdp.
[sdp @ 0xb1ef00] Format sdp probed with size=2048 and score=50
[sdp @ 0xb1ef00] audio codec set to: (null)
[sdp @ 0xb1ef00] audio samplerate set to: 44100
[sdp @ 0xb1ef00] audio channels set to: 1
[sdp @ 0xb1ef00] video codec set to: (null)I suspect that the "Non-increasing DTS" and "Header size larger than data provided" errors are caused by wrong parsing of the packets due to usage with the wrong codec.
I checked the SDP order and it seems the same as in other examples I have.
Can someone suggest an explanation ?
BTW, audio only works fine, but I guess it’s because of the simplicity of OPUS.
Thanks.
