YY3568 using pre-installed system cheese software video apparently lost frames

YY3568 when connected to the camera using the pre-installed system cheese software ,the video recording function appears obvious frame loss phenomenon.
This is because the video frame timestamp cannot be aligned with the clock and thus appears now. This is probably a problem with the gstream version of Cheese.
For this problem ,you can use the following recording commands to record

gst-launch-1.0 v4l2src device=/dev/video0 num-buffers=300 ! video/x-raw,format=NV12,width=1920,height=1080,framerate=30/1 ! videoconvert ! mpph264enc ! h264parse ! mp4mux ! filesink location=./h264.mp4

We are actively working on this issue to get cheese working as soon as possible.
