Can someone explain why Gstreamer does not play smooth video?
Same file (2500 kbit/s)
sh-4.2# /mxc_vpu_test.out -D "-i /tmp/sd/trailer_1080p.h264 -f2"
plays smoothly
sh-4.2# gplay /tmp/sd/trailer_1080p.h264
stutters:

The CPU usage of gplay is low, so I do not see what could be the cause of the timeout and stutters and frame-drops. Has this to do with A/V sync. Note that I have used a raw H.264 stream without audio or mux container.
(This is not due to VFS caching, I have changed the order of playout, and gplay always stutters).
