pleNx v0.1.12

Player

• Changing the audio or subtitle track no longer stops playback with a
  "playback error" on PS Vita. In transcode mode a track change reloads the
  stream, but the reload happened in place and never released the hardware
  decoder, so it stalled and then failed. The reload now resets the player
  first (like episode navigation) and tears the previous transcode session
  down on the server instead of leaving it orphaned.
• Audio and subtitle tracks are now selectable during local playback from
  the file browser. The player showed the track buttons but had no handler
  wired, so they appeared to do nothing.
• A failed transcode now falls back to direct play once, instead of going
  straight to an error — a smoother recovery on constrained hardware.
• Playback errors now show the underlying mpv reason (e.g. "unrecognized
  file format") instead of a bare "playback error", making bug reports
  actionable.

Fixes

• PS Vita: the transcoder height is capped at 1080p, the hardware decoder's
  limit, so a 4K source at a high bitrate no longer produces a stream the Vita
  cannot decode.
