i am trying to play my mediamtx stream on jellyfin via live tv



scanner.m3u file

Code:

#EXTINF:1, Scanner
rtsp://192.168.1.39:8552/sdr

command used in mediamtx

Code:

ffmpeg -f pulse -ac 2 -i default -f rtsp rtsp://localhost:8552/sdr -filter_complex avectorscope=s=320x240 -preset ultrafast -vcodec libx264

Plays as it should on mpv

my issue is that there is video but i do not get any audio.
