</div>Sascha has CSI drivers for the MX27, but I'm not sure in which state<br>
they are.<br></blockquote><div><br>I think a good start point would be this driver "mx2_camera.c" that can be found in phytec GIT repository. I do not know what exactly are the lacks for this driver not going mainline, what I can say is that this driver uses PrP channel 1 which can be useful for capturing video. However if you want to encode using VPU this driver should be modified to choose PrP channel 2 so that it uses YUV planar format needed by VPU.<br>
</div></div><br clear="all">VPU support is more complicated. I don't think there is a simmilar case already in mainline. Maybe integrating VPU support in a host camera driver (mx2_camera.c) would be admitted, although AFAIK V4L does not have H.264 data type it could be added if needed.<br>
