Hi All,

i am new to imx6 and building video streaming project. right now i am confused with how to use the hardware accelerated encoder in imx. there is gstreamer and libimxvpu. As per my understanding, using libimxvpu we can access the hardware encoders and decoder functionalities. (found examples for that, but struggling with the compilation with yocto). gstreamer on the other hand have gst-fsl plugins which can do the same. As a basic requirement of my project i will need video based motion detection. I was planning to use the motion vector from h264 encoder to detect motion. (have been working in TI's platform and this is how they detect the motion). But due to this confusion i am stuck. Could anyone please help me with this? any examples for motion detection with h264 encoding would be helpful

Thankyou

Hi anjo

libimxvpu provides low-level iMX6 VPU interface
