Look at encoder demo code. You can get real framebuffer address from /dev/disp and use it in PoC h.264 encoder instead of allocating memory. https://github.com/jemk/cedrus/tree/master/h264enc There is camera app. Or look at capture application in encoder demo https://github.com/linux-sunxi/cedarx-libs/blob/master/enc_dec_demo/capture/capture.c It can be modifed to capture framebuffer.
