           Summary: [0.11] - strange behaviour with uridecodebin and
                    decodebin
    Classification: Platform
           Product: GStreamer
           Version: 0.11.x
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal

PNG showing pipeline

Attached is png showing what happens when I try to remux a vorbis file in
Transmageddon. As you see from the image the audio caps is set on uridecodebin,
but it seems on decodebin the audiocaps is set back to audio/x-raw.

What I do not understand though is that when I try to do this with gst-launch:
gst-launch-0.11 -v uridecodebin uri="file:///home/cschalle/Videos/output.ogg"
caps="audio/x-vorbis" ! oggmux ! filesink location="test.ogg"

It seems to do the right thing.
