when play a video with “overlaysink” on Freescale development board (the process is imx6q), the color will be changed unsmooth, like the marked in picture1.jpg . But it will be fine if replace “overlaysink” with “imxv4l2sink” , like the marked in picture2.jpg.
The software system is yocto2.0 . The image download from NXP office web named L4.1.15_1.0.0-ga_images_MX6QDLSOLO.tar.gz.
Did anyone meet the problem? Can you tell me what 's the root reason for this issue and how to fix it please?
Thanks for your answer, I have fixed it through enable g2d 'dither' feature. But it has another question that when playing a picture with qt4 , the color will be changed unsmooth. Please give me some advice , thanks!!!
