I re-did the test because I had not put in the environment variables.
RADV (AMD) need different ones... https://www.phoronix.com/news/RADV-Vulkan-Video-VCN4 ===== The RDNA2 support remains off by default and there is no word from AMD yet when they may be providing updated firmware for the video events compatibility. Otherwise the support can be enabled via the *RADV_PERFTEST=video_decode* and *RADV_PERFTEST=video_encode* environment variables manually. ==== but my hope was to see if libplacebo can be used with vaapi decode as noted in ffmpeg docs: https://ffmpeg.org/ffmpeg-filters.html#libplacebo ==== Interop with VAAPI hwdec to avoid round-tripping through RAM: ffmpeg -init_hw_device vulkan -hwaccel vaapi -hwaccel_output_format vaapi ... -vf libplacebo ===== It seems to me that the result is similar:
