I have gstreamer udpsrc pipline which works perfectly. But I need to crop only region of the video stream dynamically, i mean to change region coordinates while pipeline is playing. How to achieve that?
Obviously opengl should be used here, but how can it be achieved? glshader?
Let's take an example my surface view size is 500x500 pixels and my native
window size is same but some how my native window takes some rectange
stracture only. I want my video to fit/shrink/stretched with my surfaceview.
