We are now using imxg2dcompositor to compositing camera and videotestsrc.Using gstreamer1.0 as bellows.All videotestsrc is ok,but add imxv4l2videosrc or imxv4l2src is err as bellows.

Kernel 4.9.88  and using the latest gst-imx plugins...

gst-launch-1.0 \
imxg2dcompositor name=c background-color=0x223344 \
sink_0::xpos=0 sink_0::ypos=0 sink_0::width=400 sink_0::height=300 sink_0::fill_color=0x00000000 \
sink_1::xpos=400 sink_1::ypos=0 sink_1::width=400 sink_1::height=300 sink_1::fill_color=0x11111111 \
sink_2::xpos=200 sink_4::ypos=150 sink_4::width=400 sink_4::height=300 sink_4::fill_color=0x44444444 sink_4::alpha=0.5 ! \
queue2 ! video/x-raw, width=800, height=600 ! imxg2dvideosink \
