I've got Zoom = 1/8 implemented but need to get the PCM wrapping in there. Sherman, how is that coming along?

I'll get right on the W64 porting. Thank you for your forebearance.

Code's done for DGIndexNV W64 wrapping. I updated the DGIndexNV user manual too.

Over to you, Rocky.

Thank you, Sherman. I'll make a release first thing in the morning.

As a reward, I'll ask Mr. Peabody to let you stay up an extra hour tonight.

I checked many HDR10 movies and everyone has "Chroma subsampling : 4:2:0 (Type 2)" in MediaInfo. Do you think X265_CL must contain one more option --chromaloc 2 ?

I don't know what X265_CL is, and it doesn't seem related to DG stuff.

DGDecNV slipstream 207:

* Added a line X265_CL to the bottom of the HEVC index file (for HDR PQ streams) containing command line
parameters for x265.exe derived from the colorimetry, HDR metadata, and frame count. This line
can be cut and pasted to your x265 invocation. :salute: Boulder

Ah yes, dementia setting in. I'll look into whether there is enough information in the input stream to definitively set this option.

Default undefined (not signaled)
https://x265.readthedocs.io/en/default/ ... -chromaloc
MediaInfo displays "Chroma subsampling : 4:2:0" in encoded movie, without Type 2 if chromaloc not set in x265.

Please re-download build 2053 and update DGIndexNV. I snuck this feature in for you. Thank you for the suggestion.

Thanks. It may help other people to create more correct 4k HDR videos

Would it be possible to have DGDecode output the native bitdepth of the source? My point is that for HDR sources, I could do the motion analysis in MVTools in 10-bit domain and then denoise in 16-bit domain for a nice little speedup. It doesn't make sense to dither down to 10 bits in this case as the final output will be 16 bits anyway.

No, I mean the output you get from DGSource. As far as I know, both Avisynth+ and Vapoursynth accept YUV420P10 happily.

You can use ConvertBits(). Is it so terrible?

NVDec gives me 16-bit output. You know that, right?

Actually I didn't know that 16-bit output is what the NVidia decoder gives you ;)
I'll test if there is any actual visible difference if I dither down to 10 bits and use that as an analysis clip. It won't be used for the actual final output so chances are that it's faster and not distinguishable at all.

You don't have to dither. Most likely the lower 6 bits are all zeros. They just need to be truncated by ConvertBits() if that is important for you.

DGDemux parser integration

Post by tormento »

It would be nice to have the same parser as DGDemux to select the correct mpls looking at lenght and streams, instead of needing to find it with other programs such as DGDemux itself or eac3to. :salute:

You already have the code, just make DGIndexNV capable of selecting a single file (usual behaviour) or give a "0" in the file field to select the whole directory.

P.S: I gently remind you language preferences too. :mrgreen:

I'll consider it but honestly I'm not highly motivated for it.

Perhaps would be easier to launch DGIndexNV from DGDemuxGUI with the selected playlist.

This would be lot less work for you.

Minor feature request: Isn't it time for a version bump of dgdecnv? it's been stuck on 2053 for years now and probably has had over hundreds of changes slipstreamed.
