Changing appsource caps dynamically

[Nostalgia]

Hello everyone,

I have this pipeline : appsrc - omxh264enc - filter - appsink.
I am using appsrc to push  raw video frame to the pipeline,  frame size (or
resolution) is changing dynamically, so I must change appsrc caps before
pushing frame to the pipeline.

Is it possible to do this change ? If yes, what steps do I follow to change
caps without need to unref the pipeline ?

Thanks in advance for your help,
