openRTSP -- no output #53

Open iconoclasthero opened 2 months ago

iconoclasthero commented 2 months ago

Stream's coming from mediamtx server.
(but I'm not ruling out something on the server side): mpv rtsp://fqdn:8554/mpd/mpd.opus mpv can play the stream to [pipewire-]pulse (presumably, as it shows up in pavucontrol)

Seemed to compile fine after installing libssl-dev on Rhino Linux 2024.1/Ubuntu devel/noble.

mpd sends the stream to mediamtx with this audio output:

audio_output {
     name            "pipe to ffmpeg - suffix"
     type            "pipe"
     enabled         "no"
     format          "48000:16:2"
     command         "ffmpeg -loglevel error -hide_banner -y -f s16le -ar 48000 -ac 2 -vn -i - -c libopus -b:a 64k
-f rtsp rtsp://localhost:8554/mpd/mpd.opus"
}

MediaMTX RTSP config; only 8554 is open to the server so perhaps it's that?
