I’m interested in learning about how to interface with the MDP for image manipulation and acceleration using Yocto Linux and the Genio 520, can someone point me to documentation or some examples that explain how to do this, or does this require an NDA?

Hi @jjohnson ,

The MDP driver exposes the standard V4L2 M2M device interface.

Please refer to the following documentation for examples (GStreamer::v4l2convert):

https://mediatek.gitlab.io/aiot/doc/aiot-dev-guide/master/sw/yocto/app-dev/video/video-common.html#software-vs-hardware-decoder-and-converter

Alternatively, you can follow the V4L2 M2M device documentation on kernel.org.
