It appears you have a Sandy Bridge CPU and the required packages installed for hardware video decoding (https://en.wikipedia.org/wiki/Intel_Quick_Sync_Video#Hardware_decoding_and_encoding). So that should work. Maybe Seb has a point...
Can you please also:
1. Run 'vainfo' and send us the output.
2. Try playing the video with 'mpv' and send us the output that 'mpv' prints to the terminal when playing the video.
