[Cin] System ffmpeg Vulkan video transcoding fails - while benchmarking works

[Andrea paz]

OK; the new test:

export RADV_PERFTEST=video_decode,video_encode
time -p ffmpeg -init_hw_device vulkan=vulkan -filter_hw_device vulkan
-hwaccel vulkan -i hdr_02.mp4 -vf libplaceb
o=colorspace=bt709:color_primaries=bt709:color_trc=bt709:range=tv -c:a
copy -c:v rawvideo -f nut -benchmark /dev/null
[...]
Stream mapping:
 Stream #0:0 -> #0:0 (hevc (native) -> rawvideo (native))
