You need to link the elements properly. gst_element_link_many connects
the elements like a chain. In your example the following pipeline will
be created:
source1 -> decoder1 -> conv1 -> source2 -> decoder2 -> conv2 -> adder -> sink
That does obviously not work. I would think that using two link calls
should do the trick:
gst_element_link_many (source1, decoder1, conv1, adder, sink, NULL);
gst_element_link_many(source2, decoder2, conv2, adder, NULL);
The first call builds the following pipeline:
source1 -> decoder1 -> conv1 -> adder ->sink
While the second call results in the following pipeline:
source1 -> decoder1 -> conv1 ->
adder -> sink
source2 -> decoder2 -> conv2 ->
Which is the pipeline you are expecting.
Hope it works.
Cheers,
Paul
