Possible missing dependency in flatpak: yt-dlp

[MayeulC]

Describe the bug Trying to play live TV, I have some output in the log regarding missing yt-dlp.

To be clear, I am not entirely certain if that's the actual issue here. In jellyfin-media-player, live tv errors out for me, and offers me to restart with transcoding. If I select "retry", it works. On the jellyfin side, I use rtsp-simple-proxy to proxy the rtsp stream provided by my ISP (udp-only, iliad/free) to the jellyfin docker container (tcp).

To Reproduce (may require a specific environment)

1. Play a live TV stream from jellyfin
2. See error in the console

Expected behavior

• Ideally, live TV would work
• More realistically, a retry with transcoding on may be necessary

Desktop (please complete the following information):

• OS: Arch Rolling
• Flatpak version 1.15.1

Generally MPV only tries to use Youtube-DLP only after failing to load the stream normally. I haven't done anything special in MPV Shim to support live TV, so there may need to be a fix applied for this.
