[FFmpeg-user] Initialising hardware device fails with error -17

[Xiang, Haihao]

Hi Martin, 

/usr/lib64/libmfxhw64.so.1.35 is for legacy HWs, you should install the vpl
runtime for your i9-13900. libmfx-gen.so is a link to the vpl runtime. For
example, below is the runtime in my system:

$ ls -l /usr/lib/x86_64-linux-gnu/libmfx-gen.so*
lrwxrwxrwx 1 root root        17 Apr 24 10:09 /usr/lib/x86_64-linux-gnu/libmfx-gen.so -> libmfx-gen.so.1.2
lrwxrwxrwx 1 root root        20 Apr 24 10:09 /usr/lib/x86_64-linux-gnu/libmfx-gen.so.1.2 -> libmfx-gen.so.1.2.10
-rw-r--r-- 1 root root 114212224 Apr 24 10:09 /usr/lib/x86_64-linux-gnu/libmfx-gen.so.1.2.10

Please install the runtime component via apt/yum etc or install the library to
/usr/lib64 when building the runtime from source code, then retest.
