Send playback codec details to support
When a video will not play correctly, codec details help support understand whether the issue is the file, the device, Jellyfin transcoding, subtitles, or Phyn playback.
This article explains what to collect before contacting support.

Check whether:
- The same item plays in Jellyfin Web.
- Other videos play normally in Phyn.
- Lowering playback quality changes the result.
- Turning off subtitles changes the result.
