!!! existing preserved libs:
>>> package: dev-libs/libcdio-2.1.0-r1
 *  - /usr/lib64/
 *  - /usr/lib64/
 *      used by /usr/bin/mpv (media-video/mpv-0.29.1-r1)
 *      used by /usr/lib64/ (media-video/mpv-0.29.1-r1)

So the package should either :=-dep on libcdio, or stop linking to it.

This is a little weird looking:

 readelf -d /usr/bin/mpv | grep -i cdio
 0x0000000000000001 (NEEDED)             Shared library: []
 0x0000000000000001 (NEEDED)             Shared library: []
 0x0000000000000001 (NEEDED)             Shared library: []

Esp as only libcdio_paranoia is stated as a dep ( and lacks subslot ops on that dep too, even though readelf suggests it necessary )

Looks like the -l flag is provided by libcdio_paranoia:

./build/config.log:Checking for cdda support (libcdio)
./build/config.log:['x86_64-pc-linux-gnu-pkg-config', 'libcdio_paranoia', '--libs', '--cflags', 'libcdio_paranoia']
./build/config.log:out: -lcdio_paranoia -lcdio_cdda -lcdio -lm

And indeed:

x86_64-pc-linux-gnu-pkg-config libcdio_paranoia --libs --cflags 'libcdio_paranoia'
-lcdio_paranoia -lcdio_cdda -lcdio -lm

CCing in sound@ as this might be a bug in libcdio_paranoia
