Ah, good to hear. Thank you. You probably noticed most of the goodness for PQ is at the top end of the range for white and it is nonlinear. HLG in contrast works much better and feels linear. I'm going to try linearizing the PQ parameter range, it's a GUI issue and a functional one, because we are l...

OK, hlg_test.rar is back online so re-download and update DGIndexNV. Have at it!

Found some more bugs. Temporarily withdrawing. Standby...

Umm, OK.

I fixed a small bug in DGIndexNV in the test package, so please re-download and update for testing.

OK, girls and boys, I have stuff ready for your testing. I want to wait for your feedback before releasing formally. The package is here: http://rationalqm.us/misc/hlg_test.rar Please read the docs carefully as the parameters have changed. This was quite a non-trivial revision so your careful testin...

Finished all my certs, concussion protocol and doping stuff was new this year. Good to go until end of 2020.

Back to work...

UHD friendly drive and that disk are now on order for debugging.

Thanks. Gonna be a few days as I have to complete some coaching certification renewal training first.

Can you please give me a link to purchase the exact same disk you have? Will I need a UHD capable drive to rip it with MAKEMKV?

I think by "mainline" Bullwinkle didn't mean Avisynth but meant the official DGDecodeNV (i.e., not have a separate CUDASynth package). Your point is well taken and further integration into Avisynth+ itself remains under study.

I've got HLG to SDR working in DGIndexNV. It's kinda nice. You can set up the HLG conversion and then just click and unclick 'Enable HDR to SDR' to see the difference between real HLG conversion and backwards compatible display. The color shifts from backwards compatible handling become very obvious...

gMKVExtractGUI does care about COMP_PREPEND. It has implemented support for it (good!). The MKV parsing code that the MKV guys kindly provided to DG tools (thank you Mike!) did not support header removal, which is is just fine for me. Adding support for it would need (up to) weeks of effort for very...

Whee!

I've got the HLG EOTF re-coded and working. And I have DGHDRtoSDR() modified to support both PQ and HLG via a mode parameter. I'll add the HLG support to DGIndexNV and then give y'all both of them. Whee!

That file uses an obsolete no-longer-supported compression method, COMP_PREPEND, otherwise known as the infamous "header removal". MKVTOOLNIX 6.6.0 removed this capability completely. You can remux the file to fix it for applications that don't support this obsolete feature. I will improve DGIndexNV...

Great, thank you. You are so kind.

I tried both of these. Each simply brought up a player and played the stream. I could not see how to download the stream.

Released in slipstream 187.

DGDecNV slipstream 187:

* Fixed regression caused by bringing back DELAY in demuxed filenames. For AC3 in transport streams the demuxed filename is wrong. [Xunkar]

OK, found and fixed the bug. Will be in the next slipstream. Thank you Xunkar for pointing this out and providing a stream for debugging. It is thanks to people like you that DGDecNV can continue to be improved.

Just discovered there is a BT.2100-2 while I was coding off of BT.2100-1. The HLG EOTF is a bit different in BT.2100-2 so I'll have to revise the implementation accordingly. No big deal.

Sweet, thank you. Investigating...

Please cut a sample from one of the M2TS files that can be used to duplicate the problem, upload it somewhere and give the link here. 50 MB should be fine. Make sure the problem occurs with the sample. Thank you.

Thank you, zys4416 . I have the HLG EOTF coded and apparently working. I want to compare the results to the HD versions you linked, and also to the results of some other conversion filters. If things look good, I'll implement it fully into DGHDRtoSDR (with a mode parameter for PQ or HLG) and add it ...

The HEVC info dialog now shows an HDR field that notifies of specification of PQ or HLG transfer function in the input stream (slipstream 186).
