Description:
mpv has support for shared-library plugins ("cplugins") since ~6 months ago, but this is disabled unless opted-into at ./configure.
It would be nice if the package would pass configure the --enable-cplugins flag to enable C plugin support.

Additional info:
mpv 1:0.25.0-5
mpv loads C plugins from the same directories as its lua scripts, and from a security perspective the .so vs lua distinction isn't important, as both have the same level of privilege and run inside the mpv process.
The support isn't a complex and shouldn't add much to binary size. For users without any C plugins there should be no change in mpv behavior. The directory is scanned regardless because it's already used for lua plugins, so there shouldn't even be more disk reads.

Thanks!
