How to use Remuxing, re-encoding, compression with web cam

[LeoDog896]

Hello! I'm trying to remux my webcam in order to get it working in firefox (repeated from other issues: #1443), but the guide on it is a bit confusing as it's asking me to replace my existing configuration. If possible, can someone add an example for the camera with a remux? (It seems to be a very common issue:

• WebRTC doesn't support H264 streams with B-frames #1491
• Missing audio in webrtc stream produced by the server #1443
• Support reading h265 with Webrtc #1448
• opus not support in hls output #1396
• WebRTC has NO audio in browser #1329

Hello, the sample configuration present in the guide is an example on how to "re-encode an existing stream, that is available in the /original path, and publish the resulting stream in the /compressed path". If you need to re-encode any stream you like in any path, it's enough to add the runOnReady parameter to the configuration that corresponds to your stream:

paths:
  mycamera:
    source: rtsp://url-of-camera
    runOnReady: ffmpeg -i rtsp://localhost:$RTSP_PORT/$RTSP_PATH -pix_fmt yuv420p -c:v libx264 -preset ultrafast -b:v 600k -max_muxing_queue_size 1024 -f rtsp rtsp://localhost:$RTSP_PORT/compressed
    runOnReadyRestart: yes

  # remember to add another path to receive the compressed stream
  compressed:

HI @aler9 . I am also facing a hurdle here. Must my original path have a '/original' and my remuxed have a '/compressed'?
I am trying to do the following.
ffmpeg -i rtsp://localhost:$RTSP_PORT/$MTX_PATH -pix_fmt yuv420p -c:v libx264 -preset ultrafast -b:v 600k -max_muxing_queue_size 1024 -f rtsp rtsp://localhost:$RTSP_PORT/compressed/$MTX_PATH.
The remuxed stream is not available on the specified path. Kindly assist
