i want to share audio over network so that i can use my tv as a wireless speaker. so i chose obs studio to make a stream out of my system audio coz i had it installed already. i went to settings -> output (advanced) -> recording (custom) and set ffmpeg output to output to url and set the url to udp://192.168.43.87:8081 and set container format to mp3 just to get started. so to test things out i ran mpv udp://192.168.43.87:8081 on the same machine and it plays audio. but when i tried accessing it from my android phone with mpv client, it doesnt play the audio, it just shows black screen for while and return to main menu of mpv app. thanks in advance.
