On an 8 year old i915, I'm guessing Ivy Bridge, you should get video
acceleration with libva-intel-driver. You may also want
libva-intel-hybrid-driver. It should, at very least, work though it may not
help. The media-driver requires a newer GPU. Braodwell or newer, though. On
my 10 year old Sandy Bridge system the CPU utilization for playing an H.264
encoded video dropped CPU from 60% to about 10%. I could even play video
with a compile running as long as the compile was niced.
