I know there are many question similar but no one is complete and clear to me

vainfo to check if you see the entry points for some profiles:

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.
Then setup vlc to use hardware decoding, run it from the command line (to get the debug messsages) and open am .mp4 file. You should see:
sudo apt-get install i965-va-driver libva-intel-vaapi- driver vainfo
[0x1781058] main libvlc: Running vlc with the default interface. Use 'cvlc' to use vlc without interface. libva info: VA-API version 0.35.0 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_35 libva info: va_openDriver() returns 0 [0x7fd825a569a8] avcodec decoder: Using VA API version 0.35 for **hardware decoding**.*
It will fail if you don't have hardware encoding support for your sandy bridge graphics (HD 2000/3000 GPU). Note it fails for me (Core i7, HD3000 graphics) and according Intel it shouldn't, because HD2000/3000 supports H.264 HW encoding....
