We already have 0003-rpi-fix-linking-errors.patch, so I've renamed to
0004-libva20.patch and applied, thanks.

I see that mpv-0.28 (which includes this change) has been released, so
it might be worth bumping the version.

this bump is not possible atm, quoting https://github.com/mpv-player/mpv/
releases:

"This release needs recent FFmpeg (newer than 3.4) due to major 
refactoring."

Such a ffmpeg version was not released yet, mpv depends on the master 
branch of ffmpeg.

Regards, Bernd
