Suddenly slow transcoding Sony Bravia KDL

[rameus]

Suddenly I have slow transcoding rates and I have no idea why since my configuration has been the same for about a year. CPU and RAM are not a problem and the storage space of the source files has not changed. Tried various settings with manual triggering of the transcoding, as well as media device profiles.

TV: Sony Bravia KDL-55HX850
Transcoding rate: max 20fps
File types affected: mkv, avi, mp4
Mezzmo version: 3.4.4.0
