HDR encoding

[mparade]

The filename was missing in the place of "-" that is why I thought that was the reason for crashing.
File name has nothing to do in the encoder call, it should only appear in the decoder call.
I doubt that has anything to do with why anything is crashing.

Ok.

No hybrid assumes the source to be more than 8it otherwise it wouldn't use format="YUV420P16".

It looks like it thinks you set the encoder to 8bit output and thus creates 8bit output for the encoder. (=> make sure you set the output bit depth in the encoder properly)

I have set the output bit depth to 12 bit surely.

Hybrid doesn't offer anything to convert bt.709 to bt.2020 it only offers to signal a specifc matrix (through the encoder).
I don't know of any way to convert SDR to HDR content.
-> if you know of a way to do a bt.709 to bt.2020 conversion using Avisynth or Vapoursynth, let me know and I can add support for it in Hybrid.

Ps.: small side note normally HDR is 10bit not 12bit. 12bit is only used by Dolby Vision afaik.

But I do not want to convert bt. 709 to bt. 2020 (SDR to HDR). The source is HDR as I stated earlier. I just want to signal the info which is already in the source.
The source is using 10 bit main profile 4:2:0 and I want to convert it to 12 bit main profile 4:2:0. The renderer I am using will be simply dithering the source to the bit level of my display.

Please help!
