[meta-freescale] about muti camera preview for imx6q

[lengyu]

Hi All
We use kernel 4.1.15 and the lastest bsp from yocto to do two camera preview on imx6q sabresd board.


1. We refer below site:
https://community.nxp.com/docs/DOC-93788
But some sink can not find.


2. refer i.MX_Linux_User's_Guide.pdf use imxcompositor_g2d to preview.


gst-launch-1.0 imxcompositor_g2d name=c background-color=0x0000ff composition-meta-enable=true \
sink_0::overlay-top=0 sink_0::overlay-left=700 overlay-left=0 sink_0::overlay-width=640 sink_0::overlay-height=480 \
sink_1::overlay-top=700 sink_1::overlay-left=120 sink_1::overlay-width=640 sink_1::overlay-height=360 ! \
queue2 ! "video/x-raw, width=640, height=480" ! overlaysink overlay-width=480 overlay-height=360 \
imxv4l2src device=/dev/video1 ! queue2 ! c.sink_0 \
imxv4l2src device=/dev/video2 ! queue2 ! c.sink_1


use this command i could see one camera.
So who can tell me how to do multi overlay which use the lastest bsp packge?


TKS.
