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.
