Public bug reported:
After upgrading from Wily to Xenial, vlc scaling and zooming is now
incorrect for h264 videos playing on i965. See attached screenshot "vlc-
vaapi.png" for a clear depiction of the problem.
Four test cases:
1. With libvdpau-va-gl1 and i965-va-driver installed, video is displayed with
the wrong aspect ratio and does not scale properly. Screenshot is vlc-vaapi.png
and terminal output looks like this:
VLC media player 2.2.2 Weatherwax (revision 2.2.2-0-g6259d80)
[0000000000758148] core libvlc: Running vlc with the default interface. Use
'cvlc' to use vlc without interface.
libva info: VA-API version 0.39.0
libva info: va_getDriverName() returns 0
libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/i965_drv_video.so
libva info: Found init function __vaDriverInit_0_39
libva info: va_openDriver() returns 0
2. With libvdpau-va-gl1 but not i965-va-driver installed, video is the same as
#1 (vlc-vaapi.png) but terminal output is a little different:
VLC media player 2.2.2 Weatherwax (revision 2.2.2-0-g6259d80)
[0000000000758148] core libvlc: Running vlc with the default interface. Use
'cvlc' to use vlc without interface.
libva info: VA-API version 0.39.0
libva info: va_getDriverName() returns 0
libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/i965_drv_video.so
libva info: Found init function __vaDriverInit_0_39
libva info: va_openDriver() returns 0
3. Without libvdpau-va-gl1 (and regardless of installation status of
i965-va-driver), playback works perfectly. See vlc-vaapi-no-vdpau.png. Terminal
output looks like this:
VLC media player 2.2.2 Weatherwax (revision 2.2.2-0-g6259d80)
[0000000000c29148] core libvlc: Running vlc with the default interface. Use
'cvlc' to use vlc without interface.
