@swick I don't see why HDR wouldn't work? It's open source, you can make the firmware grab the raw bits if need be. Obviously has bandwidth limitations but as long as you don't need to test the corner of the resolution/color depth matrix...

@marcan Thinking more about the metadata, InfoFrames, VSC SDP, ...

But sure, you can still test if the pixels are as expected, no matter if its SDR or HDR and that's already really useful.

Hector Martin replied to Sebastian

@swick We can capture all the raw metadata too, it's an FPGA. I'm actually thinking of just having it dump the entire frame bitstream and doing all the decoding in software, so we can have really fancy diagnostics for CI.

Sebastian Wick replied to Hector

@marcan I thought, at least on chamelium, that there is a display controller chip in front of the FPGA? TBH, I didn't look that closely into it yet. If we can get the entire bistream in software that would be amazing and indeed everything required for testing HDR as well.

Hector Martin replied to Sebastian

@swick Not on NeTV2, it goes straight into the FPGA and we can get the entire bitstream.

@marcan @swick Lol, been chatting about that at XDC with Leo from AMD. We agreed that any open Chamelium would need to act more like an oscilloscope and less like a normal receiver. Specify your trigger, wait for the symbols to come. Decode that using your CPU.

This way, everything new feature can be tested without having to hack the gateware, including USB, Audio, .... Also means that testing anything related to DP-MST would be much easier than with real hardware.

We both have an NeTV2 now :D
