Hello.

$ uname -a

Test with vlc 1.

config:

[postproc] # Video post processing filter

vout=xcb_xv

stderr:

Vlc hung after about 10-20 seconds and ignore TERM signal. It was killed by
"kill -9". No errors in dmesg.

Test with vlc 2.

avcodec-hw=vaapi_drm

Video file was played normally.

Flash video works normally.

So. Right now it seems OK. The problem with "avcodec-hw=vaapi_x11" may be in
X11 driver or vlc but I think the DRM driver works normally.
