so, after installing in /usr/local it need this

guest at slax:/dev/shm/libvpl-2022.2.5/build$ source /usr/local/etc/vpl/vars.sh

basically add environment variables ...

now vpl-inspect, system_analyzer and sample_decode works!

guest at slax:/dev/shm/libvpl-2022.2.5/build$ ./sample_decode -sw h264 -i
stream.264 -o out.yuv       CONFIGURE LOADER: required implementation: sw

====

stream.264 raw elementary h264 stream was created by ffmpeg:


ffmpeg -i ~/0005.avi -c:v libx264 stream.264

file stream.264
stream.264: JVT NAL sequence, H.264 video @ L 12

but ffmpeg (git commit 73b3344edd39468cb3f729d613949f52dbcba84e compiled
with ./configure --enable-libvpl)

still reports

[mjpeg_qsv @ 0xb478f40] Error creating a MFX session: -9.
