I've been using jit.qt.movie @colormode uyvy for high-speed transfer to the GPU, but today I noticed that it looks quite different than other methods.
This patch shows three different image pipelines for the display of YUV content:
(These are to demonstrate color, not speed.)
1) jit.qt.movie (default rgb colormode) --> jit.argb2uyvy --> jit.slab @file cc.uyvy2rgba.jxs
2) jit.qt.movie (default rgb colormode) --> jit.gl.texture
3) jit.qt.movie (uyvy colormode) --> jit.slab @file cc.uyvy2rgba.jxs
All 3 look different! It seems to me that #3 is the "right" representation of the data, since it matches Apple's Preview app. Notably, this is the only one that uses jit.qt.movie's uyvy mode. What method does jit.qt.movie use to convert to RGB? Am I missing something?
