Source error on a certain file

[Feuerqualle]

Hello,
I am having an issue where I cannot play a specific episode of a Blu-Ray rip in the Android app (it just says "source error"). It plays fine on Debian and if I use VLC on Android instead of the integrated player. The other episodes from the same disc also play fine. The episode is saved as a mkv, 8,16 Mbit/s, 23,98 fps, 1.920 × 1.080 (as are the others that are playing, although the bit-rate differs a little).

The logs just show the following entries when trying to play back the episode on the integrated player in the Android app:

Code:

[DATETIME, TIMEZONE] [INF] User policy for "[JELLYFINUSER]". EnablePlaybackRemuxing: True EnableVideoPlaybackTranscoding: True EnableAudioPlaybackTranscoding: True
[DATETIME, TIMEZONE] [INF] StreamBuilder.BuildVideoItem( Profile="Jellyfin Android", Path="[PATHTOFILE/FILE].mkv", AudioStreamIndex=null, SubtitleStreamIndex=null ) => ( PlayMethod=D>
[DATETIME, TIMEZONE] [INF] Playback stopped reported by app "Jellyfin Android" "2.6.0" playing "[EPISODE NAME]". Stopped at "0" ms

There is no FFmpeg Log for this play attempt, but there is one for playing a different one (all of them seem to be for linux Playbacks thought):

This usually means there is something wrong with the video. Some players are more sensitive to bad files. VLC will play just about anything and just power through it.
