Contributor I

Hi !

 There are descrptions "Two non-overlapping windows" "Picture-in-picture "In IMX6DQRM.pdf page 459 about it's supported applications.  I  have added two camera devices and corresponding drivers in SABRESD board. Each camera can work in test-pattern mode and can display chess board on LCD in OVERLAY way. But I am not able to display two camera images on one LCD simultaneous. could anybody give some clues ?

Hi tang,

You may try using overlaysink plugin, as described in section 7.5 (Overlaysink usage) of

“i.MX_Linux_User's_Guide.pdf” :


“The overlaysink plugin is based on the GPU. It provides two main functions for video rendering:

• Video Overlay: composites multiple video playbacks into the same display.

• Multiple Display: shows videos to multiple displays, up to four displays.”


Please refer to section (Multiple videos overlay) for example.


Also, please look at section 7.3.16 (Video composition).
