Trouble playing some media files

[TheDreadPirate]

VLC isn't a good measure for whether a file is good or not. VLC will power through corrupt/malformed files.

Jellyfin does not have its own playback engine. We use open source players like MPV in Jellyfin Media Player. But all/most of our other clients we are reliant on how tolerant the device's embedded player is to malformed/corrupt files. Most tend to skew towards requiring files be formatted properly and standards compliant while having a low tolerance for corruption.
