How do I read source data from a FILE* ?

[Giles Atkinson]

On Linux, you can just run playbin2 with "uri=file:///proc/self/fd/10" to take input from file descriptor 10.  I suspect there may be no equivalent on Windows.

Appsrc may be a more portable solution.  You need to run a small function that is called from appsrc whenever it needs a new input buffer.

I need to also be compatible with Windows.  I suppose _fileno() would 
work there.

But looking at the docs of playbin2, the "source" property is read-only. 
  It doesn't appear I can set it to an fdsrc?
