So I was experimenting with Vulkan decoding in cinelerra-gg. After some fight I get build using ffmpeg git commit 038314bc6be2f35a82e9fba2228bcac2e4fee648 for ffmpeg here is bunch of errors like this: [hevc @ 0x6f7465c0] Could not find ref with POC 296 [hevc @ 0x6f7465c0] Error constructing the frame RPS.
