Had to dig a bit into VLC as I'm not familiar with it as I do for FFmpeg. First, the only QSV support in VLC is for encoding, and only to H.264/H.262, which is very limited. In comparison, FFmpeg can use QSV for encode/decode in all formats supported by QSV. The only plugin making use of libvpl in VLC us the qsv encode plugin: ldd /usr/lib64/vlc/plugins/codec/libqsv_plugin.so | grep vpl libvpl.so.2 => /lib64/libvpl.so.2 (0x00007fb2220cc000) Using it for a simple encode to a h264 file fails: ~/Videos> cvlc oceans.mp4 --sout "#transcode{vcodec=h264,venc=qsv}:standard{access=file,mux=mp4,dst=blargh.mp4}" vlc://quit VLC media player 3.0.20 Vetinari (revision 3.0.20-0-g6f0d0ab126b) [000055cbb441f010] dummy interface: using the dummy interface module...

I compared with FFmpeg QSV code and its has libvpl specific init code if it is compiled with libvpl. So for converting a program from mfx to vpl it looks like there is more than an include swap. Or something else I do not know. Anyway, there's no need to spend more time on this, as the number of people using the abysmal VLC QSV support for H264 encoding must be super low, and VLC will probably update to working libvpl support at some point (4.0). And for the one user of VLC/QSV, he can be redirected to use FFmpeg which is much much better. -- You are receiving this mail because: You are on the CC list for the bug.
