HandBrake

Yes the code is on https://github.com/HandBrake/HandBrake , build instructions https://handbrake.fr/docs/en/latest/dev ... ndows.html

Try to disable all the overclocking and similar things in the BIOS. Unfortunately it seems there are many similar reports: https://wccftech.com/intel-13th-14th-ge ... -in-korea/

Could be, but the whole init_delay code seems unnecessary, the other encoders uses a different way to avoid non-monotonic timestamps, and the muxer doesn't use the init_delay value anymore for video tracks.

Try to set the frame rate to constant. I think the qsv encoder handling of timestamps can be improved, probably I will be able to check soon.

A lot of these players are the same device rebranded and sold by a different companies, so it's no wonder they have the same bugs.

It would be a good thing to report that issue to the Dune device maker so they can fix their software.

Are those only in the preview window, or in the encoded file too?

Right, but you were talking about the "duplicated" HDR10 mastering metadata, not the Dolby Vision data.

It is, open the mkvtoolnix gui, select the "header editor" tab, and check the Video track "Color information" and "Color mastering meta information".

HDR10 metadata and the color tag are written both in the container and in the video bitstream. If you think it's the cause of your issue, mkvtoolnix header editor can be used to remove them.

Uhm the configure script checks already for cargo and cargoc, unfortunately it seems it doesn't disable libdovi if you force it on.

Yes, if the system reboots, it's not HandBrake's fault.

There are been a few reports of such issues on Intel CPU with many efficiency cores. But no one in the developer team has one to test so there isn't much at the moment we can do.

I think it has been fixed in 1.7.3.

The media engine is a separate part on the chip, and it's probably almost the same as the M1, plus the addition of an AV1 decoder. So the CPU and GPU performance won't affect the speed much when all the job is done by the media engine. It would be interesting to compare the quality of the output, ma...

Can you share a sample file we can use to reproduce the issue?

Yes actually the option should be available, please post the scan log so we can have some more info on your source file.

DTS can only be added to the MKV format. 1.3.3 showed impossible options.

I think your video has a short frame at the start that breaks QSV. Try setting a constant Framerate.

Does it work if you use a different encoder?

The GTK GUI doesn't support multiple parallel encodes yet, it has been implemented only on Windows and macOS at the moment.

Yes, the issue is that your cpu has so many cores, but video encoding can't scale too well to more than 12 cores anyway.

The mastering display color volume info can be added manually in the additional options field, but first you need to know what's the actual info. Do mediainfo reports them in the source file?

You could try to run caffeinate in your script, that should avoid sleep.
