I'm sometimes quite stuck with the software I use, trying to make it work rather than looking for something new.
But I finally made the switch to Celluloid on desktop and mpv on Android, and it is working so much better for me than VLC did!

#Celluloid #mpv

#Celluloid ist eine Kamera-App für #macOS. Sie ist #OpenSource und ermöglicht einerseits die Aufnahme des Videostreams von der Kamera am #Mac und andererseits kann man damit selbigen mit Echtzeitfiltern für die Videokonferenz z.B. in Zoom behübschen.

I've been experiencing segfaults while using Celluloid to watch certain YouTube videos and decided to investigate... It appears that there is a bug in the intel-media-va-driver reporting support for AV1 support on my Tiger Lake GPU:

- https://github.com/mpv-player/mpv/issues/14941

- https://trac.ffmpeg.org/ticket/11213

To workaround this, I configured mpv to have yt-dlp avoid AV1 files by adding the following to my ~/.config/mpv/mpv.conf

ytdl-format=bestvideo[vcodec!^=av01][height<=1080]+bestaudio

This has yt-dlp pick the best video format that isn't AV1 and is no more than 1080p, while choosing w/e is the best audio format.

So far, this has fixed the issues of Celluloid crashing while playing some YouTube videos.

#mpv #celluloid #ffmpeg #ytdlp

MPRIS is a neat mechanism that allows media players to communicate what is playing and provide playback controls.

Unfortunately, this was not working in the snap version of celluloid, a mpv + GTK media player.

After some digging around (and grepping dbus-monitor), I discovered a quick fix:

https://codeberg.org/sameersharma2006/celluloid-snap/pulls/12

Basically, rename the DBUS path to something allowed by the snap appamour profile.

I happy to say that the change worked and is now merged!
