Conversion Encoder or decoder not found?

SquirbleSquirble Members, Plex Pass Posts: 37 Plex Pass

I have some files that plex can't play. When I try I get "Conversion Encoder or Decoder not found". These files were ripped from DVDs. I rip all my dvds the same way. This is the first I've come across this error. The files play fine just using a media player on the PC. Any suggestions?

    I'm having the same problem. Any suggestions would be great. I've attached a screenshot of the message on iPhone. It also happens on Mac, Apple TV, and others.

    The files are MKV.

    Yes they are - mkv and hevc. It's never been a problem before. Any suggestions?

    Im having the same problem. Most of my files work fine but i have a large handful that error out: "Conversion encoder or decoder not found."

    They work when I open them with VLC, but not Plex. Thanks,
