I would like to know which package I have to install and how to test that is working fine?
I know there are many question similar but no one is complete and clear to me
libva-intel-vaapi-driver
vainfo
Then run vainfo to check if you see the entry points for some profiles:
[...]
vainfo: Supported profile and entrypoints
VAProfileMPEG2Simple : VAEntrypointVLD
[...]
For all GStreamer-based video players, this package should be sufficient: gstreamer0.10-vaapi . If I'm correct most standard video players like Totem are GStreamer based.
VLC is a different story, but it's being built with the --enable-libva build flag in Ubuntu (as shown by the apt-get source vlc). This means it should just work by enabling it in the configuration:
Or, manually, on the command line:
vlc --ffmpeg-hw -v
[...]
libva: VA-API version 0.32.0
[0x7feeecc02a28] avcodec decoder: Using VA API version 0.32 for hardware decoding.
