Dear List,
I'm trying to directly output a captured video signal to an LVDS panel
on an imx6q. Capturing frames works fine using the staging imx-media
driver. I can grab JPGs using v4l2grab and I can stream the input to the
display with gstreamer. However, when streaming, one of the cores is
utilized by ~66%, and I have to use the videoconvert module of gstreamer.
The IPU in imx6 can directly stream an captured signal back to the
display processor (DP) according to [1]. While the capturing paths
within the IPU are managed by the staging media-imx driver, its output
paths are not, so I can not simply set up links using media-ctl.
So, my question is whether it is possible to hook up the captured signal
to the DP using either the ipuv3 driver or the frame buffer driver
(mxcfb) or something else, and if yes, how?
Thanks for any help and/or hints
Stephan
