Mixing cameras on gstreamer

I’m using gstreamer to mix two cameras on a video, but, on apalis iMX6 it’s too slow. Is there some way to do this with hardware acceleration?
My code so far:
gst-launch-1.0 videomixer name=mix sink_1::sync=false ink_1::xpos=100 sink_1::ypos=100 \
! autovideosink sync=false \
imxv4l2videosrc device=/dev/video0 \
! mix.sink_0 \
imxv4l2videosrc device=/dev/video1 \
! mix.sink_1

hi @alfredo

Welcome to the Toradex Community!

Could your provide the software version of your module?
Which type of cameras are you using?
What is the resolution and fps of your videos?
Could you also the share the cpu Load?
