how are *all* the pipelines elements involved?

[Rossana Guerra]

Hello, tanks for your response, I'm aware of GstParse, but I need a
'customization' of this pipeline actually, and doing it by code, that's why
I asked. I need to add subtitles and other time-based elements to an avi
file.

This is my actual pipeline,

                               mad ---- ffdec_mpeg4 ----queue-----alsasink
//audio part

filescr---avidemux ----

                               queue---autovideosink  //video part


Thanks

Rossana
