[gst-devel] Two filesrc and adder: switching "location" does not work

[Mathis Hofer]

Well it seems that pastebin.com is a bit overloaded...

Here is a simplyfied drawing of the pipeline:


filesrc ! decodebin ! audioconv ! volume
\
adder ! capsfilter ! volume ! alsasink
/
filesrc ! decodebin ! audioconv ! volume


The two streams before the adder are in musicbin resp. noisebin.

I really hope someone can help me out...
