Important information

Android version: FireOS latest version

mpv-android version: any

Which version of mpv-android introduced the problem (if known): It's never worked

Description

There's a problem with how Fire OS reports hardware acceleration compatibility, and most apps can't fetch the list correctly. That makes MPV use software decoding for the Hi10p (or H.264 10-bit) codec instead of properly using the Stick's capabilities, which leads to a lot of stuttering, as the processor isn't fast enough to decode video in software.

The solution to this is to make a bypass that tells the backend to ignore the compatibility list provided by Fire OS, and to hardware decode the Hi10p codec anyway. This can be done by identifying the compatible models through their ID.
