Issues with H264 Decoding, SDP Codec Collision & SRTP Errors

[AmitaiFenster]

Question

I'm running a React-based frontend app that streams RTSP video from Ethernet cameras via MediaMTX. The video generally works, but I encounter repeated errors at different times. Occasionally, frames are dropped, and the video gets "stuck" momentarily. Here are the main errors I see:

ERROR:h264_decoder_impl.cc(397)] avcodec_receive_frame error: -11  

ERROR:sdp_offer_answer.cc(390)] A BUNDLE group contains a codec collision for payload_type='96. All codecs must share the same type, encoding name, clock rate and parameters. (INVALID_PARAMETER)  

ERROR:srtp_transport.cc(137)] Failed to unprotect RTP packet: size=1210, seqnum=7532, SSRC=3094770139, previous failure count: 0  

System Configuration:

• Cameras: RTSP over Ethernet, TCP, H264 encoding, 25 FPS
• MediaMTX Configuration: Paths are set via API, just setting the path name and source
• Frontend: React app receiving the video stream using WebRTC

I've attached my MediaMTX configuration and logs for reference. Any ideas on what could be causing these errors and how to resolve them?
