Boblight with hardware decoding

Is there a way to get boblight working with hardware decoding (platforms I'm testing are Odroid C2, Raspberry Pi 3 and 4)?

It has to work fine on OSMC some time ago, and stopped with some update. Now I want to run my multimedia center with all features, and one of them is Amblone instalation, serviced by Boblightd on Linux. This part works fine. Problem is with playing videos (the most important thing) - when I enable DRM PRIME hardware acceleration, boblight doesn't work. When I disable DRM - boblight works fine, but performance is very poor (as the video is decoded by software). I guess the problem is with DRM (some protection that avoid boblight to get image), because some time ago Kodi didn't support that (I don't know if it stopped working with version that came with DRM support, but it is possible).

Is there any way to get it both (Boblight AND hardware decoding)?

external HDMI grabber

You mean HDMI splitter + some USB dongle to capture HDMI video? That would be very expensive soultion. Or there is some cheap dedicated stuff?...

Devices that run GBM/DRMPRIME graphics do not support software grabbers

Do any of supported by LibreELEC single board computers support hardware decoding with software grabbers?

And, from Hyperion Github:

There is an outstanding Kodi fix for that.

Now I understand how much that mean

It looks like it is the end of my Odroid C2 tests as multimedia center. Working boblight was my mistake, 5.1 sound won't work for me and additional SPDIF output is probably much more complicated than described in their website.

Not so fast. As mentioned, chewitt also has a C2, so stay tuned until he did some testings.

I'm not throwing away this board and I'll be very happy to hear it work but at this moment I see no benefit over Raspberry Pi (where sound works) - boblight has same problems, secondary sound output has unknown status (for Raspberry Pi I have HiFi-Berry, which sounds great, and the only problem is to configure system to stream sound via two sound cards at the same time - I have done it on OSMC, but it stopped to work with some update, and simply copying my configuration to LibreELEC doesn't work too).

I have even older LG TV - before smart TV era. But it works well (which is good information for all LG TV owners) and I don't want to change it. So this is not an option.

About grabbers and splitters - well, grabber can be not as expensive. Splitter - probably will be problematic (and expensive too), if I want to use HDMI CEC.
