mkvmerge.exe is missing for Windows 64bit

[zmarty]

mkvmerge.exe is missing from this repo for Windows 64bit

I am not sure what is the difference between the mkvmerge.exe that is supposed to be here and the one I downloaded from MKVToolNix.

I have an H.264 HDR video that I exported from Davinci Resolve. As expected, it looks washed out when played on an SDR screen.

I used mkvmerge.exe from MKVToolNix:

mkvmerge.exe ^
  -o ProjectOutput.mkv ^
  --colour-matrix 0:9 ^
  --colour-range 0:1 ^
  --colour-transfer-characteristics 0:16 ^
  --colour-primaries 0:9 ^
  --max-content-light 0:1000 ^
  --max-frame-light 0:300 ^
  --max-luminance 0:1000 ^
  --min-luminance 0:0.01 ^
  --chromaticity-coordinates 0:0.68,0.32,0.265,0.690,0.15,0.06 ^
  --white-colour-coordinates 0:0.3127,0.3290 ^
  ProjectInput.mov

Then I uploaded ProjectOutput.mkv to YouTube.

Unfortunately YouTube did not detect it as HDR, as far as I can tell, since the HDR to SDR conversion did not seem to trigger. Here is the video: https://www.youtube.com/watch?v=uuXxGgZROtY&feature=youtu.be

Hi,

good question on mkvtoolnix... I've used mkvmerge from it today to upload a HDR video with VP9.2 codec and it worked fine. Maybe there are some differences when using other codecs.

I confirm no HDR treatment has happened to your uploaded video. Are you sure your video was in a supported 10 or 12bit codec? according to the documentation: https://support.google.com/youtube/answer/7126552?hl=en it can be VP9 profile 2, h264 10-bit, ProRes 422/444, or DNxHR HQX.

Hi, zmarty I had a look at the bitstream you uploaded. It seems you uploaded a 8bit H264 bitstream. To trigger the HDR-SDR conversion, you have to wrap a 10bit stream in mkv.

Thanks for pointing out the issue with the binary. It is the same as mkvtoolnix. I will replace mkvextract with mkvmerge.

Thank you. The problem was indeed the type of video (8 bit H.264 instead of 10 bit H.264).

Suggestion: Some sort of warning or notification would be useful (if somebody uploads an mkv with HDR metadata but with an unsupported video format)/

I switched to using DNxHR HQX + mkvmerge and it worked. I am however facing a couple of other issues I will opening bugs about.
