Describe the issue

I have successfully published microphone audio to the MediaMTX server through FFmpeg, and when I accessed the WebRTC, the MediaMTX server returned the error: 'closed: the stream doesn't contain any supported codec, which are currently AV1, VP9, VP8, H264, Opus, G722, G711.

Describe how to replicate the issue (ffmpeg commend)

1. start the server
2. publish audio source with this ffmpeg commend
   ffmpeg -i audio="Microphone (Yeti Stereo Microphone)" -c:a aac -c:v h264 -ar 44100 -b:a 1M -ac 1 -f rtsp rtsp://localhost:8554/test-1

Did you attach the server logs?
