[gst-devel] file descriptor sharing among different elements

Hi,

Currently, they do.  There are plans to in the future have remote
pipelines (ie, in other processes, on other machines), but in that case
still you'd know and it'd be clear you can't pass the fd.

I think it should be easily doable; get the srcpad, get its parent,
which is the element, then check if it supports the interface.  Why
would you want to do this ?
