[gst-embedded] Using Filesrc for synthesized formats

[Edward Hervey]

Hi,

  Just store the EOS event in your decoder until you've outputted all
the samples, and at that point push the EOS event downstream.
  The modplug element (from gst-plugins-bad) does something very similar
to what you're trying to achieve (it needs the whole file and then can
start decoding).
