What kind of phone is this? And are you using the integrated player or web player in the app's client settings?

Hi !

The Phone i a samsung S23 with actual (no custom) software and i use the internal player...

Can you share the ffprobe output of this file?

[goerdi]

here we go

Your file still has the DV8 metadata attached. DV8 is HEVC only. Its presence is probably breaking exoplayer.

I wrote a guide for removing Dolby Vision, but it is for HEVC files and I'm not sure if this works for a file that is already AV1.

You can try anyway with this modified command.

Code:

/usr/lib/jellyfin-ffmpeg/ffmpeg -y -hide_banner -stats -fflags +genpts+igndts -loglevel error -i "/path/to/dv_video.mkv" -map 0 -bsf:v av1_metadata=remove_dovi=1 -codec copy -max_muxing_queue_size 2048 -max_interleave_delta 0 -avoid_negative_ts disabled hdr10_video.mkv

Swapping hevc_metadata in the bitstream filter with av1_metadata.

I took a peek at the jellyfin-ffmpeg code. "av1_metadata" should work the same as hevc_metadata in my guide with HEVC.

Hi !

Is there a way to remux it ?

Ciao Gerd

[TheDreadPirate]

In real time? No. But the command I provide does NOT require re-encoding. It is just stripping out the Dolby Vision metadata and nothing else.

Hi !

Yes this is what i meant.. its possible with a tool like mkvmerge ?

Ciao Gerd
