Still picture, 50% chance works.
Moving picture, shit always happens. It is really moving, but it should show static still image.

PS: I use phone camera recorded 240fps video, and use ffplay count every frame, true 25fps and true 24bit color.
Hopefully I can fix it today. Looks like there are some data corrupt or timing issue. :p
