there are many garbage when play video with overlaysink for yocto2.0 on imx6q development board

[adamzhu]

 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.

Commands as follow:

gst-launch-1.0 playbin uri=file:///H.264_1080x1920_30fps_40M_mp3.mov   video-sink=”overlaysink”

gst-launch-1.0 playbin uri=file:///H.264_1080x1920_30fps_40M_mp3.mov   video-sink=”imxv4l2sink”

         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?
