Subject: [PATCH] fix(player): keep hardware decoding after a transient
 VideoToolbox failure

Some HEVC files carry a frame Apple's hardware decoder refuses to decode
(kVTVideoDecoderBadDataErr on an otherwise conformant P-frame). mpv fell
back to software decoding for the rest of the file after the first error,
and 4K HEVC software decode drops frames every few minutes on Apple TV.

MPVKit b8b922ec carries an mpv vd_lavc patch that keeps the configured
fast fallback while probing but lets a hardware decoder that has already
delivered frames ride out a mid-stream error burst: the burst one
undecodable frame causes ends at the next keyframe by construction, so
fallback now requires errors to survive two keyframe intervals. Verified
against the reporter's sample: playback logs "Hardware decoding
recovered after 90 errored frames" and stays on VideoToolbox instead of
switching to software.

close #2167
