I do not know of any existing cons of SRT, so supporting it would make sense.

If allowed in the config to set srt://x.x.x.x instead of rtmp:// that's pretty much all we'd need from the looks of it.

In theory, you could try:

camera_name:
  gstreamer:
    inputs:
      - path: srtsrc uri="srt://127.0.0.1:7001" latency=0 name=rtp_stream
        roles:
          - detect
  detect:
    width: 1920
    height: 1080

Though you have to build this branch manually for your platform.

I am sure they exist, but I personally have not seen cameras that support srt yet. Which cameras do you know of that support srt?

This is vs RTMP as in the first post, which is for output from frigate, to view on other systems instead of RTMP? ffmpeg supports SRT fine

frigate is taking RTSP, not RTMP as input... converts to RTMP (and can convert to SRT too, is what I am asking)

Got it.
