There are no reasons whatsoever why push cannot work for literally anything.

The driver and the hardware do not care where in the VLC code paths the buffers 
are allocated. Ultimately, the push model is just about allocating buffers in 
the source component rather than the sink component - and that is just a 
software construct.
