Hello Sir,

We do preview live video, like below

1. 1280 x 720 is not good, we can not preview

2. 1920 x 1080 FPS 30 decrease to 8 (performance not good)

Any parameter is wrong?

(1) /etc/init.d/weston stop

(2) gst-launch-1.0 v4l2src device=/dev/video0 ! video/x-raw,width=1280,height=720,framerate=30/1 ! fpsdisplaysink

The attached are image recorded.

Hi Michael,
Can you let us know the SDK version used here?
Is this v3.04?

Did you check with yavta ?

Please also give a try with dmabuftest and check if you are getting expected output.

Thanks
RamPrasad
