JRVR Status, Plans and Upcoming Changes
audunth:
Hi,
I just tried it and got a black screen, no video. So first question: Does it work with Windows 7 at all?
Hendrik:
We don't generally test with Windows 7 any longer, since it's out of support by Microsoft and will no longer receive future updates.
What I would recommend to test would be disabling hardware accelerated decoding, because I know for sure that won't work on Windows 7.
Otherwise, open a new thread and attach logs (individual support should be kept out of these central threads), maybe we can see something simple and obvious. But there are no guarantees that it will work on 7.
audunth:
Thanks, Hendrik.
I disabled Hardware Acceleration when possible (which was on) and restarted the computer (which I hadn't done since installing 28) but it didn't work. Will make a new thread. :)
Hendrik:
28.0.86 is coming soon with quite a bunch of JRVR changes
NEW: HDR10 pass-through with Red October JRVR.
NEW: Support for 10-bit output with Red October JRVR.
You can now pass-through HDR10 on Windows (and theoretically on Linux when using Vulkan, but its harder to test). JRVR will pass both the original HDR10 data (converted to RGB, naturally), as well as the HDR10 metadata to your TV, so hopefully we'll get accurate HDR10 rendering.
HDR10 pass-through is only available if the HDR option in Windows is enabled. To make that process easier, there is a separate option available to toggle Windows HDR when playing a HDR file.
That process is not quite seamless, and can feel as disruptive as changing the resolution, hence it needs to be explicitly enabled. If you are on Windows 11 already, it might be easier to keep it enabled at all times and tweak the SDR to HDR conversion to your liking, if possible.
To make HDR10 work properly, JRVR now also supports 10-bit output on Windows, which can also be enabled for SDR. We may automate that in the future if we can either figure out that your display is actually 10-bit, or we let you configure the display bit depth, but for now you can enable 10-bit SDR in the Advanced settings.
How do you know if 10-bit output is on and working, or HDR pass-through is on?
NEW: Added an information on-screen display to JRVR (Ctrl-J to toggle).
You can now press Ctrl-J to show an information display on the video, which shows video properties, as well as the output mode. Performance metrics are not currently included (queue size, renderering time), as we first need to implement measuring them. Note that Ctrl-J is not a "global" hotkey, and if its not working, make sure you focus the video window, for example by clicking onto it.
And finally, to also help testing and comparison, forwards frame-stepping is now supported in JRVR.
NEW: Support for Frame-Stepping (Shift-Right Arrow in Pause) with Red October JRVR.
Note that this update includes a big change to the internal architecture and some dependencies, so please keep an eye out for any new breakage, so we can deal with it!
lepa:
Nice! So HDR on Linux could also possibly work. That's great news.
ctrl-j is used to check new MC version. Is it now changed or does it still do both? As MadVR also uses ctrl-j for OSD maybe it would make sense to change update check to some other shortcut
