APT Pinning Broken?

["maria.shrivinski" <maria.shrivinski@proton.me>]

Hello, I would like to build with bookworm as the distribution while installing the package mpv and ffmpeg from sid (unstable).

According to the Debian Live Manual this should do the trick:

config/archives/live.list.chroot​

deb http://deb.debian.org/debian sid main

config/archives/live.pref.chroot​

Package: mpv

Pin: release n=sid

Pin-Priority: 600

Package: *

Pin: release n=sid

Pin-Priority: 1

This gives a low version error because live-build tries to install mpv's dependencies from bookworm release, which has default Priority 500, while sid now only has Priority 1 for anything but mpv.

The following packages have unmet dependencies:

 mpv : Depends: libarchive13t64 (>= 3.4.0) but it is not going to be installed

       Depends: libasound2t64 (>= 1.0.27)

       Depends: libavcodec61 (>= 7:7.0)

       Depends: libavdevice61 (>= 7:7.0) but it is not going to be installed

       Depends: libavfilter10 (>= 7:7.0)

       Depends: libavformat61 (>= 7:7.0)

.......

If I set the sid Priority higher or equal to bookworm's, all packages are installed from sid because of higher version numbers.

Is there a way to only install mpv including its dependencies from sid, while all other packages are still installed from bookworm release?

Thank you so much and have a nice day!
