Onn 4k can't play DV files - sisu - 2025-03-02
I have an Onn 4k that is hooked up to a 1080p Projector. I'm playing a 4k DV file and it only shows a blank screen while the sound is playing fine.
This device can play HDR/DV file, but if it's just DV file it's just a blank screen.
Things I noticed:
- The project is 1080p, onn 4k is a 4k and HDR (no DV). When I stream, it's Direct Play.
I tried:
- Turn on Jellyfin Server's tone mapping
- Disable Onn's device HDR capability to force Jellyfin transcode, but still direct play.
Is there anything else I missed?

If you set the audio to stereo on the Jellyfin Android TV client, it should trigger transcoding. Is the file you're trying to play a Hybrid DV/HDR10+ file?

EDIT: I figured it out. I disabled Android TV Jellyfin's Bitstream Dolby Digital stream and everything works as expected.

I force
downmix to stereo got a little further. It shows video now, but the coloration is totally off (as if tonal mapping is not right). Not only that, it will only play a few seconds then crash the player (Jellyfin error encountered retry...).Here's the file profile that I'm trying to stream, it is DV only, not hybrid. Hybrid file works.
