Dear All,

 

I have a question about preview function with FullHD (1080p) @30fps in i.MX6DQ.

I tested the below command with L3.10.18 (gstreamer 0.1x) and succeeded the preview function.

$ gst-launch -v mfw_v4lsrc device=/dev/video1 capture-mode=0 ! mfw_v4lsink disp-width=1920 disp-height=1080

 

But, in case of L3.14.28 (gstreamer 1.x), the frame rate is too low (about fps (11.091fps)).

$ gst-launch-1.0 imxv4l2src device=/dev/video1 ! 'video/x-raw,format=(string)UYVY,width=1920,height=1080,framerate=(fraction)30/1' ! imxv4l2sink

 

==X-11 result==

Total showed frames (206), playing for (0:00:18.573332669), fps (11.091).

 

==fb result==

Total showed frames (203), playing for (0:00:18.273803669), fps (11.109).

 

Could you tell me the way of preview with 1080p@30fps to HDMI display in gstreamer 1.x?

 

Best Regards,

Keita
