Remove image jitter on playback #23

Closed dahnielson closed 14 years ago

The OpenGL consumer can not currently handle the correct ITU-R Rec. BT.601 pixel aspect ratios without having the image jittering unstable on playback.

Turned out that the solution was simple: The consumer property "rescale" defaults to "bilinear" and was passed to all scaling MLT filters. Setting it to "none" removed the jittering.

There's no rationale for having MLT scaling the image for us as the OpenGL consumer is quite capable in that area.
