Help: Publishing via C#

[ksmuthucv]

Hello Team,
I’m trying to publish raw nals of a frame (h264/h265) to the mediamtx server using C#. Can you please advise what must be done to publish, successfully? Below is what i’m trying to do as of now.

1. Get the vps (h265 only), sps and pps.
2. Connect to the server.
3. Send sdp as part of ANNOUNCE to the server. (would assume, similar to client-publish-format-h265/main.go, publishing with gstreamer? #40 media.Media)
4. Start sending the entire frame (h264/h265) nals (byte[]) to the server (not sure any fragmentation/modification is required before sending).

URL for publishing: rtsp://localhost:8554/stream

Output from mediamtx server:

Hello, my advice is to set logLevel: debug inside the server configuration. This allows to view RTSP requests and responses in the console. Then try to publish with FFmpeg. Then try to publish with your C# client. You'll be able to clearly find the differences.

Was able to solve the publishing with help of debug comments! Thanks @aler9
