Now i’m developing rendering yuv frames with opengl for qml. Video frames can display correctly. But other items display wrong contents. Text item becomes white rectangles. Image item displays a part of video frame, the color is gray. If I render rgb frames instead yuv frames, all works fine.

in “VideoOutput” item.
this is the result if rendering yuv with opengl is used
the buttons should be
