<div dir="ltr"><div style>I'm having issues playing back certain videos using mplayer and vaapi. It usually results in the audio getting out of sync pretty quickly with video not being able to keep up. mplayer usually will spit out a message that the system is too slow to play this, but system almost uses no CPU !?</div>
I'm using the latest Intel drivers (2.21.6) and va-intel-driver 1.0.20 on a Ivy Bridge hardware (Intel NUC*). <div style>Comparing two videos where one doesn't work and the other plays fine:</div><div><br><div><div style>

I also have the same exact problem when I switch from vaapi to the gl backend of mplayer. The x11 backend seems to work fine (no sync issues), but shows frame tearing.</div>
