Universal Media Server | Forum

When I play certain films the first frame appears and then the video and audio freeze.
On other films, the video freezes on frame on, but the audio continues.
Thirdly (!) some films "seem" to play okay but then the film periodically freezes.
All three films are MKV but play on in PS3 Media Server (although I wouldn't find going back to that software as a solution, for other reasons).

I've attached log files, hopefully someone can help?!

Probably the difference is that we automatically mux videos to avoid transcoding when possible. This works for most files but for certain uncommon files it can cause problems. You can switch to how PMS does it by going to the Transcoding Settings tab in the program, and unticking "remux videos with tsmuxer" in the FFmpeg subsection
