I am onto something. I realized that this whole time I've been using vdpau for output. Here are results: -vo vdpau (adding -vc ffh264vdpau lowered CPU % but did not make difference) -- video very smooth, but slowly drifts out of sync (lags behind). If I seek to another location, it goes back in sync and starts drifting again -vo vdpau -framedrop -- video smooth and stays in sync, but once every 20-30 seconds jerks noticeably. I am assuming to sync back up with audio. -vo vdpau -hardframedrop -- stays in sync, but a bit choppy, not a smooth as above. It is more tolerable than just -framedrop -vo xv -- stays in sync, but a bit choppy especially on high motion scenes. CPU usage is higher. -vo gl is same as -vdpau -vo gl:swapinterval=0 -- stays in sync and video pretty smooth, but seems I am seeing a bit of tearing I will try it later today on a more powerful computer and see which looks best. So far my 2 choices are -vo vdpau -vc ffh264vdpau -hardframedrop or -vo gl:swapinterval=0 Thank you again. -TJ
