Combining data from two chain_functions

[dv]

Both chain functions should get called. However, if the connected 
sources run in the same thread, then this may cause problems. For 
example, udpsrc elements create new threads. If two udpsrc elements are 
connected to two sinkpads of the same element, then both udpsrc elements 
in their respective threads will push buffers downstream, and the 
associated chain functions are called. Of course this also means that 
you have to take care of the synchronization inside your element - if 
both chain functions modify the same data, then you must use something 
like mutexes to make sure you don't get race conditions.

As for your pipeline, try using queue elements between the sinkpads and 
whatever you connected to the sinkpads.
