Describe the bug

Seeking doesn't work for a few videos, forward or rewind results in playback starting from the beginning. Resuming the video also results in the same. This behavior is only for a few files, one such file's media info is attached. When requested for a transcoded version, seeking works perfectly. Issue is only with direct play.

When transcoding, the server re-encodes the video into a more compatible format, allowing seeking to function properly. The issue could be video encoding.

Try ffmpeg -i "Filename.mkv" -c:v copy -c:a copy -movflags faststart "Output.mp4" or ffmpeg -i "Filename.mkv" -c:v copy -c:a copy -map 0 "Output.mkv"

I am experiencing the same for many videos, though I cannot discern a pattern. Transcoding is enabled for all formats - except AV1 (which I have no videos in).

Seeking works fine on the regular Android app and on Windows and in all browsers - only in the AndroidTV app seeking always causes the video to restart, no matter what. I can also confirm that the video in question is in fact being transcoded, as the web player shows "Play method: Transcoding" under "Playback info".

This issue started to happen fairly recently, but I cannot say whether it was after a Jellyfin server update or an AndroidTV Jellyfin app update.

// edit: Interestingly, Windows Media Player is also unable to seek these videos. And both Windows Media Player and Jellyfin report the videos to be much longer than they actually are. A 50 minute long video is reported as being 1:04h long for example. MPC-BE is also having issues playing back these videos. So overall I think these are just badly encoded videos.
