* properly scale subtitles with qsv and vaapi

* fixes

CHANGELOG.md

@@ -15,6 +15,7 @@ The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/).
 
 ### Fixed
 - Skip checking for subtitles to extract when subtitles are not enabled on a channel/schedule item
+- Properly scale subtitles with QSV and some VAAPI configurations; now all configurations will scale subtitles
 
 ### Changed
 - `HLS Direct` streaming mode
