Hello, Sir:
Our board have two MIPI-CSI2 interfaces and I can have two camera preview separately (not the same time).
I'm trying to enable two camera preview simultaneously on HDMI on i.mx8m.
I use gstreamer to output to waylandsink or kmssink but can't get it work.
The software is Yocto rocko (linux 4.9.88 BSP).
I refer to
https://medium.com/@petehouston/play-two-webcams-in-mjpg-format-simultaneously-using-gstreamer-2302c...
to give instruction:
gst-launch-1.0 tee name=splitter \
v4l2src io-mode=2 device=/dev/video0 \
! video/x-raw,width=640, height=480 \
! waylandsink splitter. v4l2src io-mode=2 device=/dev/video1 \
! video/x-raw,width=640, height=480 \
! waylandsink splitter.
refer to

to give instruction:
gst-launch-1.0 -vv \
v4l2src io-mode=2 device=/dev/video0 ! \
videobox autocrop=true border-alpha=0 top=-70 bottom=-70 right=-220 ! \
videomixer name=mix ! \
video/x-raw,width=640, height=480 ! \
waylandsink \
v4l2src io-mode=2 device=/dev/video1 ! \
videobox autocrop=true border-alpha=0 top=-70 bottom=-70 left=-220 ! \
mix.
Is there any way to preview two MIPI-CSI2 camera at the same time?
Thank you~!
BR,
Richard
