10 bit and lossless (FFV1 and H265)

[johtamaa]

1. How to get "yuv422p10le" parameter in Hybrid, when encoding with ffv1 codec?
2. How to get "lossless" parameter in Hybrid, when encoding with h265 codec?

---

2. I noticed that there is custom comman line addition in x265, where I can give parameter "lossless".

How to get "lossless" parameter in Hybrid, when
encoding with h265 codec?

• set 'x265->Base->General Settings->Encoding mode' to 'constant quantizer (1-pass)'
  
• enable 'x265->Base->General Settings->Lossless'
  

How to get "yuv422p10le" parameter in Hybrid, when encoding with ffv1 codec?

Not sure I added support for that. -> will check

Checked. Hybrid doesn't support 10bit FFV1 encoding atm., but it's easy to add would have send you a link to a dev version for testing which supports it, but got no clue what OS you use.

I use Windows 10 and media-autobuild_suite ( https://github.com/jb-alvarado/media-autobuild_suite ), so latest ffmpeg is in use.

Send you a link to a dev version which uses the input bit depth when FFV1 is used.
(simply extract the download into your Hybrid folder)

10-bits should be selectable, because not every files are 10-bit. I don't know if audio passthrough all is right way to straight copy, no sound is heard. The audio metadata is not moved to correctly.

seems like mkvmerge keeps the mov wrapper around the pcm stream.
Would need a (small) sample to play around to see if I can somehow convince it to not do that.

10-bits should be selectable, because not every files are 10-bit.

Since FFV1 is meant as a lossless codec I think it sticking with the input is normally the right way to go, but I'll think about it.

I used to in second time pcm to audio encoding, 24bit Litlle Endian and it works now. Thanks!
