Due to arch-arm needing a rebuild for the new libplacebo one can if desired remove mpv to go through the updates and temporarily use vlc or download / install the mpv rebuild I have built after going through the update process. Arch-ARM knows about the mpv issue:

There is also new mesa and and xfce updates. In addition I also pushed rpi-ffmpeg-7.1.1-3 libplacebo rebuild to unstable when the mirrors sync for those that uses it.
