No sound in my pipeline

[Rossana Guerra]

Hi Nicolas, thanks for your response, I show the pipeline I am using. It
does a transition-crossfade effect wich works prerfeclty, except sound (no
sound) :

bin
-----------------------------------------------------------------------------------------------
  alpha --------------------
                              |----------videomixer ------------
fmpegcolorspace
  smptealpha ----------
       ^
       |
-----------------------------------------------------------------------------------------------
       |
  Controller   // it controls the start-duration property of smptealpha



composition
--------------------------------------------------------------------------------------------------------
    gnlfilesource
                     |           gnloperation // contains the *bin*
described above
                     |
    gnlfilesource

--------------------------------------------------------------------------------------------------------

gnlfilesource is for each video

pipeline

According to this pipeline it need another gnlsource for each video, then,
how I 'plug' them?
I'll try to work around what you said.
