     I am working on Video overlay & recording project. It involves,


1. Capture the image from a camera in YUV format.

2. Overlay & de-interlace the image & show to the display (fb0) using a IPU.

3. Read the image from the FB0 and convert it from RGBP to YUV420 fromat.

4. pass it to VPU to encode in H.264 format.


I am using mxc_ipu_hl_lib & libvpu, no G-streamer.

So is it possible to read image from FB0 & apply the colour space conversion?
