I make a SD boot card(imx-image-full-imx8mmevk.wic) and boot EVK using the SD card. Then I plug a camera on EVK and it shows a uvc device.

I launch the following gstreamer command and output video on HDMI screen successfully.

gst-launch-1.0 v4l2src device=/dev/video1 ! 'video/x-raw, framerate=30/1, width=(int)640, \
height=(int)480, format=(string)YUY2' ! autovideosink

 

I want to output the video from uvc device to HDMI with Mjpeg type, but I launch the following gstreamer command fail.

gst-launch-1.0 v4l2src device=/dev/video1 ! 'image/jpeg,width=1920,height=1080,framerate=30/1' ! \
vpudec output-format=4 ! imxipuvideotransform ! imxg2dvideosink sync=false

The error message show as follow.

imx8mm gstreamer doesn't have imxipuvideotransform, before you use the plugins, you can use the gst-inspect-1.0 xxx to check if current gstreamer supports this or not
