    Good Day,

    I just finished setting up Jellifish and wanted to watch sonic 3, in the aspekt ratio 2.4:1, but on my tv that is unwatchable. On my pc it works fine.

    Is there anything I can do?

    Thanks!

    This is a known issue caused by a bug in ExoPlayer on devices using the MT8696 MediaTek chipset found in Fire TV 4K Sticks and the latest Google streamer. It occurs when playing media that includes both Dolby Vision and HDR10+. On TVs that support Dolby Vision, users will see a magenta/black screen with only audio playing, while on TVs that don't support Dolby Vision, a split image issue will occur.

    AndroidTV
    https://github.com/jellyfin/jellyfin-and...ssues/2630 (old issue)
    https://github.com/jellyfin/jellyfin-and...ssues/4021 (new issue)

    Exoplayer/AndroidX Media
    https://github.com/google/exoplayer/issues/11096 (old issue)
    https://github.com/androidx/media/issues/1895 (new issue)

    Workarounds:
    1. Remove DV Metadata: Follow the steps in this forum thread to strip out the Dolby Vision metadata.
      Code:
      /usr/lib/jellyfin-ffmpeg/ffmpeg -y -hide_banner -stats -fflags +genpts+igndts -loglevel error -i "/path/to/dvhdr10+_video.mkv" -map 0 -bsf:v hevc_metadata=remove_dovi=1 -codec copy -max_muxing_queue_size 2048 -max_interleave_delta 0 -avoid_negative_ts disabled hdr10_video.mkv
    2. Remove HDR10+ Metadata:
      Code:
      /usr/lib/jellyfin-ffmpeg/ffmpeg -y -hide_banner -stats -fflags +genpts+igndts -loglevel error -i "/path/to/dvhdr10+_video.mkv" -map 0 -bsf:v hevc_metadata=remove_hdr10plus=1 -codec copy -max_muxing_queue_size 2048 -max_interleave_delta 0 -avoid_negative_ts disabled dv_video.mkv
    3. Force Transcoding on ATV: Reduce the bitrate or set audio to stereo to trigger transcoding on the client.
    4. Use Kodi as an external player for the ATV client: Kodi allows you to choose the format compatible with your TV. You can disable Dolby Vision or HDR10+ as needed.
    5. Use Kodi with Jellyfin Plugin: Kodi allows you to choose the format compatible with your TV. You can disable Dolby Vision or HDR10+ as needed.
