1080p@30fps USB camera on i.MX8QM

[AndreSilva]

Dear NXP support,

I have a Logitech C920 (1080p@30FPS) camera that doesn't reach more than 5fps on the QM board running the following gstreamer pipeline:

gst-launch-1.0 -v v4l2src device=/dev/video2 ! video/x-raw,width=1920,height=1080 ! videoconvert ! waylandsink

is there any know issue ? is there any chance to get it tested on your side ?

thanks for the support.

Andre

Thanks Yuri, turned out that the logitech cam for x-raw is only 5fps, I need to use x-h264 to get 30 fps, but then my output is completely wrong. I will check for correct pipelines with h264.

thanks,

Andre

Hello,

   Please try using buffers in the pipeline (num-buffers)

   Also customers can use so called zero-copy piplining,
described in Chapter 14 (Zero-copy Pipelines) of
the i.MX8 Gstreamer User Guide.
