OMAP 5 Camera support

Hello ,

I am using omap 5 (customized for automotive) in one of our projects. We want to capture a camera image and display it on LCD.

We have linux kernel 3.4 from TI .  Is the capturing of video  from camera and displaying it on LCD uses DRM (drivers/staging/omap-drm)

OR

Is it through the normal V4l2 - > DSS interface.

Regards

Yogesh

  • Hi Yougesh,

    If I recall correctly video playback with kernel versions after 2.6.35 is based on libdce. DCE is an extension to DRM (additional ioctl()).
    Displaying video to LCD, also uses DRM:

     - So,Video capturing path should be: Application -> GStreamer framework -> gst-ducati -> libdce, libdrm ----> kernel drm/kms/dce -> kernel rpmsg -> ducati firmware ->
       IVA-HD.
     - Displaying video path goes through: kmssink (from gst-plugins-bad) -> libdce, libdrm ----> kernel drm/kms/dce -> kernel display driver (DSS)
