robin49 has a few questions about mattkhan's support for Magewell

mattkhan:
2 things to note

1) I don't expect different behaviour from MC in this case, all such players (MC, mpc-hc, mpc-be etc) just play what they're given, but this thread is specifically about use of this filter with MC so other playback software should be raised on github
2) if you put 1080p in and your display is 1080p then 4k is not relevant, it's just a 1080p source and display

mattkhan:
some fixes in latest release (https://github.com/3ll3d00d/mwcapture/releases/tag/0.4.7) around hdr infoframe parsing, the information is not actually used by any dynamic tonemapping solution as far as I'm aware but seems better to output it correctly anyway

robin49:
Bonjour Matthieu.

j'ai essayé avec jriver 33, j'ai bien une image, votre filtre apparait bien, mais l'image reste en sdr, par de hdr...
l'image est belle et très fluide.

j'ai essayé aussi dans mpc-hc, le filtre apparaissait, bien ,mais plus tard c'était impossible ouvrir mpc, en effet il se referme aussitôt.
jriver 33 est très complet mais aussi très compliqué à configurer, peut être une case à cocher...

Merci à vous

mattkhan:
Mpc-be is untested and not supported in this thread.

I refer back to https://yabb.jriver.com/interact/index.php/topic,140134.msg975324.html#msg975324 for your sdr comments. I won't repeat this, I will ignore subsequent posts that do not contain information sufficient to attempt to comment. In general if you think the output is incorrect then you need to be completely clear about what the input is. In my experience, the easiest way to test hdr is to use the magewell filter, if it's an HDR input then it will appear completely washed out because their filter doesn't handle it. If it appears normally using their filter, it's surely actually sdr.

You can also show their property page showing the hdmi input and can also look at the tab showing the hdmi HDR infoframe.

mattkhan:
to be clear on what constitutes useful debugging info, use the magewell provided filter in any suitable player that lets you access its property pages (MC, mpc, whatever) and show the contents of the HDMI HDR infoframe and the video + input specific status

I've attached examples of an SDR input and an HDR input, you will note that the infoframe is all 0s for SDR but contains a load of non zero values of HDR. Actually only 1 particular value from this is used to enable dynamic tonemapping (as seen in jrvr and madvr) but if it is all 0s then it's definitely sdr.

Reports of issues accompanied by these pics = something I can comment on
