            Bug ID: 784671
           Summary: *decodebin: [API]: autoplug-discard
    Classification: Platform
           Product: GStreamer
           Version: unspecified
                OS: All
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: gst-plugins-base
          Assignee: gstreamer-bugs at lists.freedesktop.org
          Reporter: mduponchelle1 at gmail.com
        QA Contact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

decodebin2 now emits a signal that uridecodebin relays,
letting the application decide whether a stream should be
discarded altogether, thus exposing no pad for it.

An example use case is an application that doesn't want
to filter streams based on their caps, but based on their
stream ids. It will thus wait for the signal to be emitted
with the source pad of a demuxer, and return TRUE if its
stream id is not wanted.
