Frames receive a refcount when added to the frames list so release that refcount
in gst_video_decoder_do_finish_frame(). Also release the ref on the frame
because gst_video_decoder_do_finish_frame() takes ownership of the passed frame.
This allows subclasses to override it, as is necessary for e.g. the
video-crop meta. It is now necessary that after decide_allocation()
there is always a allocator and a configured buffer pool inside the
query.
The sinkpads are unblocked when going from PAUSED->READY, we need to block them
again when going READY->PAUSED. The blocking of the pad previously only happened
when it was freshly obtained with _request_pad or when the caps changed. If we
don't release the pad when going to READY it was previously never blocked again
causing not-linked errors.
Video base classes and theora plugin still needs to be ported again

Some container formats (like AVI) set DTS on the buffers instead of
PTS.
We detect this by:
* detecting if input timestamps are non-increasing
* detecting if the order the frames come out is the same as the order
they were inputted (meaning the implementation is reordering frames).
If the decoder reorders frames, but input buffer timestamps were not
reordered, that means the buffers has DTS and not PTS as their timestamp.
If this is the case, we use set the PTS of the outgoing frames in the
same order as they were given to the decoder.
This fixes the issue for any decoder using this base class (yay).
FIXME : Don't forget to backport changes that happened to theoraenc
since April 2011
theoraenc: Don't create keyframe on time gap
There is no rational to do so, and also gst_video_encoder_set_discont() is
gone from base class.
