I've managed to get the linux media SDK to run on my Ivybridge cpu (i7-3770s), and it works perfectly. I wanted to try it on a Haswell cpu (i7-4770s). What I have found is that it works, but it runs very slowly, about 1 second per frame. The pause occurs when waiting for sync, the SyncOperation call.
My question is, does the Linux media SDK support this chip? I noticed that the i915 driver displays an error message when loading, adn there is a fixme:
[ 1.719700] i915 0000:00:02.0: setting latency timer to 64

I don't see the errors on the 3770-s, ivybridge cpu.
Thank you for your help,
