No sound in my pipeline

[rossana]

Hi, I use gnlfilesource, gnloperation, alpha channels, videomixer,fmpegcolorspace I can play the videos correctly but I can not hear the sound. If I play the video with any other application it works fine (image and sound).
What did I miss to set?

Thanks

Rossana

AFAIK, you need two separate gnlsource objects, one for video and one for audio.

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
____________________
                                  |

composition  operation |___________ queue ___________ sink

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.

it means I have to do a sort of split? I have .avi, .flv files for instance, whose properties are set on each gnlfilesource accordingly.
