[gst-devel] why is it not working ?

[Thomas Vander Stichele]

two things:

a) your code is very hard to read - please choose a coding style wrt.
spacing and braces and parentheses, and stick with it.  Alternatively,
use indent on it before posting your code.

b) I'm missing some essential code in your example; key_pressed is never
used, there are ellipses where I would like to see code, channel struct
isn't defined, ...

It would be a lot easier to try and debug a compiling example :)
