[gst-devel] multiple source to one sink

[Michael Horbovetz (horb)]

the files contain text.  one contains numerous character A's; the next
B's; the next C's.

i don't really care what order the characters appear on standard out.
i'm wondering how to link elements together to get this to work.  it
seems that an element can only belong to one bin.  does that imply that
an element can be linked to only one other element?  if so then what is
referred to in section 8.1.2 of the application development manual when
it talks about aggregator elements.

thanks,
mike
