    Jellyfin Forum Support Troubleshooting Chromecast HD not requesting transcoding for a 4K video, IF it has HDR10

    Chromecast HD not requesting transcoding for a 4K video, IF it has HDR10

    When attempting to play a 4K HDR10 file on my Chromcast HD (non 4K) Google TV, it tries to direct play and fails after repeated attempts. A non HDR 4K succesfully requests to be transcoded down to 1080p and plays fine.

    1. I play a 4K non HDR10 file, and it plays successfully.
    2. The dashboard shows it is being transcoded due to a non supported resolution.
    3. I then try play a 4K HDR10 file, which repeats a playback error until giving up.
    4. The dashboard reports it is direct playing the file.
    5. I can force a transcode of the 4K HDR10 file by lowering my max bitrate to under 5mbps
    6. This issue can be replicated with any 4K HDR10 file.

      This reminds me of a recently fixed issue with the GoogleTV app wherein any 4K file would not request to be transcoded, perhaps the recent fix is not working with files that are both 4K and HDR?

      Any help would be appreciated,thank you!

      I have attached ffmpeg logs for both an HDR and non HDR 4K file.
