I have a similar issue. I am trying to follow the docs. and use ffmpeg to feed mediamtx a live video stream.

ffplay says some things about the source stream:

Input #0, rtsp, from 'rtsp://localhost:10000/test':
  Metadata:
    title           : Session streamed with GStreamer
    comment         : rtsp-server
  Duration: N/A, start: 0.199989, bitrate: N/A
  Stream #0:0: Video: h264 (Constrained Baseline), yuv420p(tv, smpte170m, progressive), 320x240 [SAR 1:1 DAR 4:3], 30 fps, 30 tbr, 90k tbn, 60 tbc

ffplay also says some things about the mediamtx stream:

Input #0, rtsp, from 'rtsp://localhost:8554/feed':
  Metadata:
    title           : Session streamed with GStreamer
  Duration: N/A, start: 0.000000, bitrate: N/A
  Stream #0:0: Video: mpeg4 (Simple Profile), yuv420p, 320x240 [SAR 1:1 DAR 4:3], 30 tbr, 90k tbn, 30 tbc

I use this to publish the stream:

ffmpeg -i "rtsp://127.0.0.1:10000/test" -f rtsp rtsp://127.0.0.1:8554/feed

But the web interface always says there stream doesn't contain any supported codec...
