This works for me on a 920+ converting HDR 4K media with tone mapping.

It might be something media specific.

Can you show us the Media Info (bottom of detail screen) for this media?

Hi cayary,

here is a screenshot of the media information:

Could you try a conversion on a couple of other HDR10 files to see if this is isolated or not?

[PaoloPinkel 6]

Yes, I tried a conversion with a file where it has run before. The conversion is still running... 

[Carlo 4560]

OK let us know if it finishes properly.

The conversion with another HDR file was successfully performed. Why does this one file not work?

There are multiple ways how HDR side data can be encoded in an HEVC video. ffmpeg doesn't support all of them and VAAPI native tone mapping doesn't work when this data is not available.

What you can do is to install the diagnostics plugin and choose OpenCL tone mapping for VAAPI. This can work even without HDR side data.

Is that better in general than using QuickSync?

The OpenCL tone mapping is exactly the same but QuickSync is usually faster. 

[Carlo 4560]

So any reason not to just enable Quicksync and move it to the top of the list for each codec type?

Should be fine, except for MPEG2Video where QuickSync has issues sometimes.

@softworkz

your diagnostics plugin does not open, no matter if desktop (chrome and edge) or android app.

Which version of Emby Server are you running?

Emby Server log?

[PaoloPinkel 6]

Version 4.6.4.0

Thanks for your help!

Thanks for the log. Can't see anything wrong there.

Could you please go to the server dashboard in Chrome browser, press F12 to open the dev tools, try to access the diagnostic options and then watch for any errors in the javascript console?

[softworkz 5066]

Thanks a lot, that's actually the culprit. It's a change for which the Diag Plugin has already been updated in the beta channel, but I missed that this change has also made it into the 4.6.4.0 release.

Please restart your Emby Server. It should auto-detect the update for the plugin. Then another restart to complete the update and you should be ready to go.

No update is coming. Uninstalling/installing does not help either. 

[softworkz 5066]

Right, something went wrong. Could you please retry now?

Hi softworkz,

perfect, the conversion is running! Many thanks also to cayars. Great support from you.
