[gst-devel] multiple source to one sink

[Edward Hervey]

Hi,

  Do you wish to:
  * mix together the contents of the 3 files ? (result would be :
ABCABCABCABC...)
  * concatenate the contents of the 3 files ? (result would be :
AAA...BBB...CCC...)

  For the first case, mixing is format-dependant, so you need to give
us more info about the format you're using.
  For the second case, if it's audio/video you can use the GNonLin
plugins which can help you create compositions of files. It should
also work with any type of media, but hasn't been tested.

   Edward
