        --tracefile ['']             tracing file

#======== Film grain analysis ================
        --fga [0]                    Experimental: Enable film grain analysis and generate FGC SEI message

At the beginning, I will probably not support:

• setting profile, level, tier, since I (so far) have no clue what their restrictions are.
  
• encoding hdr, since I don't see how one would set the hdr10&co information in the video stream. (hdr10 could be added by signaling the parameters through the container, when mkv wss used)
  
• anything other than yuv420, since from the looks of it, the encoder doesn't support it.
  
• muxing to mkv, since mkvtoolnix does not seem to support muxing atm. (https://fossies.org/linux/mkvtoolnix/src...parser.cpp some code is there, but it's all commented out)
  

PS：How to make HDR10/DOVI metadata passthrough when encoding with libx264, libx265, and libsvtav1 in hybrid？

Hybrid does not support passthrough of dovi or HDR-10+ metadata. You have to add the metadata file to x265 in the configuration. x265 is the only encoder in Hybrid that supports Dovi and HDR-10+.
x264: afaik. H.264 has not HDR support, so if you got some decoder which would support HDR10 for H.264 you will need to add those settings through 'Config->MKV tagging->VUI->Matroska advanced video signaling'.
x265: x265->Signaling has options for HDR (
svt-av1: SVT-AV1->Signaling has options for HDR-10; according to "SvtAv1EncApp.exe --help" there are no options for dovi.

[Selur]

Uploaded a dev version with some basic support for VVenC.
Not sure whether this will be available in the next release.
Haven't tested it a lot. (only basic functionality)
Output size calculation is not correct, since:
a. I'm not sure about the overhead
b. even with 2pass average bitrate isn't hit
