Mesa 24.3 is released with many Vulkan Driver
Improvement, and implementations are expected around
the corner in rolling distributions.<br>
<br>

With ffmpeg (7.1) h264/5 vulkan encoder support, I
wonder if Cingg is ready to put them into use?<br>
<br>
<font face="Courier New, Courier, monospace">ffmpeg
-hide_banner -encoders | grep vulkan<br>

(codec h264)<br>

So assume the FFmpeg benchmarks sample was vulkan decoding
only, as they work for hdv (mpeg2) input also:<br>
<br>
ffmpeg -hide_banner -init_hw_device "vulkan=vk:0" -hwaccel
vulkan -hwaccel_output_format vulkan -i hdv09_04.m2t -f null -
-benchmark<br>

bench: utime=19.045s stime=0.313s rtime=1.702s<br>
<br>
ffmpeg -hide_banner -init_hw_device "vulkan=vk:0" -hwaccel
vulkan -hwaccel_output_format vulkan -i hdv09_04_h264_qsv.mp4 -f
null - -benchmark<br>

fmpeg -hide_banner -init_hw_device "vulkan=vk:0" -hwaccel vulkan
-hwaccel_output_format vulkan -i hdv09_04_hevc_qsv_8b420.mp4 -f
null - -benchmark<br>
frame= 248 fps=2.0 q=-0.0 size=N/A time=00:00:09.92 bitrate=N/A

hevc terrible slow !!<br>

And I found a sample encoding on reddit, which failed as assumed
for me as follows (similar for h264_vulkan):<br>
<br>
ffmpeg -init_hw_device vulkan=vkdev:0 -filter_hw_device vkdev -i
hdv09_04.m2t -filter:v "format=nv12,hwupload" -c:v h264_vulkan
hdv09_04_h264_vulkan_8b420.mp4<br>
