Black Screen When Playing 4K HDR Content on Fire Stick 4K - nastygum - 2024-10-25
I am having an interesting issue. I have a Jellyfin server running on my TrueNAS Server. I typically stream all of my ripped MKV content using the Jellyfin app on my Amazon Fire Stick, which is a 4K Gen 2 model. I also have a 4K LG TV that supports HDR but not Dolby Vision.
The Issue:
- One 4K HDR file, The Green Knight, displays a black screen while streaming on the Fire Stick, but the audio continues to play. The video player interface completely disappears while this happens. The Jellyfin dashboard says it's direct streaming.
- Other HDR content like Dune plays perfectly fine on the same setup, with virtually the exact same video media info, minus the bitrate. See attached images.
- Other video players experience the same issue as the Jellyfin app.
- The problematic file plays fine through the Jellyfin web app and other clients.
- Nothing in the logs indicates any errors.
Setup:
- Jellyfin Server: Running on TrueNAS (i7 4790, 16GB ddr3, gtx 1050ti).
- Amazon Fire Stick: 4K Gen 2 model.
- TV: LG 4K, supports HDR10 but does not support Dolby Vision.
- MKV Files: Typically 4K HDR HEVC
This issue is a mystery to me. My running theory is that the bitrate is too high for either the Fire Stick or the network. I feel like if this was the case, it would have a more graceful handling of this.
Any help would be appreciated.
Thanks!

Exoplayer, which is what our AndroidTV app uses underneath, is supposed to fallback to DV8 or HDR10 for DV7.6 content, but doesn't. This is a known issue with exoplayer.
Your options are to use the quality selector in the AndroidTV player to select a lower bit rate than the video's native bit rate. Looks like these videos are between 60-70Mbps, so selecting 50Mbps would trigger a transcode.
Your other option is to strip the Dolby Vision portion and make your video straight HDR10 since Dolby Vision 7.6 and 8 are built on top of HDR10.

That seemed to work. Transcoding kicked in and it played just fine.
Thanks for the help!
