After the latest update, half of my files no longer play at all. I have been playing with every setting for transcoding and everything I can find and can’t figure out what I am doing wrong or why the files stopped playing after the update. They are 1080p mp4 files. They used to play just fine but now they do not.
You could try to downgrade back to the version that last worked.
Or you could detail your setup and provide server logs and a player log in debug mode demonstrating the issue after a reboot.
