hevc (hvc1) playback issues, please help

[stjacob 0]

Emby server:

1. Emby Premiere got.

2. Mediasign plus got.

3. Hardware transcoding of h264 is ok on any client.

 

issue1. When the client is emby theater for windows and I checked libmpv or gpu option, the hevc playback is shatterd.

isssu2. When the client is emby for ios, the hevc playback is choppy.

issue3. When I use  web browers, the hevc playback is always working on software transcoding mode (h265 to h264).

 

please help. Did I miss any options?

Thank you for your reply.I checked all the options carefully and I found some key message maybe.

1080p HEVC HDR10 with main10 profile and  hvc1 codec tag  can not be transcoded correcttly, as below:

 

720p hecv works well:

 

here are my transcoding options:

Please provide the server, ffmpeg and hardware detection log for a specific example.

Any solutions?

[Luke 42077]

@stjacob this should be improved in the upcoming 4.7 server release. For immediate relief you can always try the beta channel. Thanks.

One addition: I found this topic through search and forgot to explicitely mention that I'm experiencing this problem on MS Windows (10) and NOT on a QNAP device (you can see that in the logs).
