------- Comment #1 from Edward Hervey  2009-03-05 07:44 UTC -------
A simpler way to expose this would have just been to construct a pipeline by
hand and not linking one of the pads.

Ex : Take a quicktime file with aac and h264 and do "uridecodebin !
audio/x-raw-int ! fakesink". This will only link the aac decoder and ffdec_h264
will not be linked.

And as far as I can tell ... it will not decode anything since we're not
providing ffmpeg with any output buffer (since we get the buffers from
downstream and it's not linked). That doesn't mean it's not calling any ffmpeg
code ! But at least it's (1) not calling the cpu-intensive parts and (2) still
has enough information so that if we decide to connect a pad all of a sudden it
will be able to carry on decoding from that point on.

Unless you come up with some logs proving it's actually decoding something,
this bug will be closed.
