I.MX6 - H.264 encoding of Framebuffer

Hi, I am trying to H.264 encode the framebuffer in i.MX6Q. My requirement is to encode and stream the framebuffer. I am able to open /dev/fb0 and grab the frame. I understand from the H.26 encoder requirements that t operates only on YUV frames. I am trying color space conversion of RGB framebuffer using IPU and then encoding using the VPU. But all these operations takes more than 100ms which I am not able to afford. Could you please suggest me a better way to do this? Is there a way I can configure /dev/fb0 for YUV and H.264 encoder can directly operate on framebuffer memory? Is there any samples available?
