and h264->hevc at 90 fps
Oh, that's amazing!
I should definitely try it on my rx6600.
And this line scales from FHD to 4k on gpu and encodes at nearly 40 fps! ./ffmpeg -hwaccel_output_format vaapi -hwaccel vaapi -i ~/botva/vid/MMC_14_may_2011_four_pilot_whales.mp4 -vf scale_vaapi=-2:2160 -c:a copy -c:s copy -c:v hevc_vaapi -f mp4 /dev/null exact vaapi_scale line from https://stackoverflow.com/questions/69243696/ffmpeg-vaapi-scale-a-video-keep... h264 encodes in this scenario at 10 fps. And vaapi_tonemap asserts in mesa: ./ffmpeg -hwaccel_output_format vaapi -hwaccel vaapi -i ~/K38_sdcard1/Documents/iPhone11_4K-recorder_59.940HDR10.mov -vf tonemap_vaapi -c:a copy -c:s copy -c:v h264_vaapi -f mp4 /dev/null ffmpeg: ../src/gallium/frontends/va/surface.c:1394: vlVaQueryVideoProcFilterCaps: Assertion `0' failed. Aborted

main detail missing was "-hwaccel_output_format vaapi".
with it I can transcode h264->h264 FHD at 42 fps and h264->hevc at 90 fps (know feature of Polaris based encoder at least under Linux). -- Cin mailing list [email protected] https://lists.cinelerra-gg.org/mailman/listinfo/cin
