WIP: video: overlay-composition: cache converted rectangles when blending (3.93 KB, patch)

Description Lazar Claudiu 2014-11-24 14:08:39 UTC 
gdkpixbufoverlay should convert its source image to the required pixel format only once and cache the buffer for subsequent use.
Comment 1 Tim-Philipp Müller 2015-06-22 15:26:40 UTC 
Really an issue in the video overlay composition blending code, not gdkpixbufoverlay (affects other elements too), so moving to -base.

WIP: video: overlay-composition: cache converted rectangles when blending

Work-in-progress patch. Doesn't work properly yet, probably because it doesn't take the fact that the RGBA from textoverlay is pre-multiplied into account when converting to AYUV. Seems to work fine with gdkpixbufoverlay though.

+1 on caching, seems the way forward, "just" need to make it work now ;-P
