Yes, it should be possible to take general design of primus and implement VDPAU offloading. I did not look at VDPAU API yet, but I expect that it's simpler than...

For reference, a vdpau/libva bridging library capable of providing hardware-accelerated video decoding on Intel chips for vdpau-aware applications is available at https://github.com/i-rinat/libvdpau-va-gl

I think to properly make your case you need to explain why using Intel hardware video decoding is not sufficient.

Thanks for your patience and reminder, and sorry for dropping this. It seems we are thinking about the issue from completely different angles. As I understood, you want extensions to...

Can you try checking how CPU frequency scaling affects it? Specifically, by checking whether using "performance" scaling governor and p-state/acpi scaling driver changes things.

Are you sure it's a problem with primus and not a regression in Mesa, Intel DRI or Intel DDX? Does `export LIBGL_DRI3_DISABLE=1` help?

It's a bit unfortunate that since it's a new install, you don't have a reference point where it might have worked well (i.e. you cannot say "it used to work...

Does this problem appear with other demos? Could you capture a trace with apitrace? Since you're able to try it now, how's performance and latency? Does `PRIMUS_SYNC=1` make a noticeable...
