Path to only reopen the decoder when new caps are different

Sometimes the pipeline is already playing when upstream element sends
RECONFIGURE event which parser receives and subsequently sends another
GST_EVENT_CAPS. The new CAPS event causes ffmpegdec to reopen decoder even when
CAPS are same and decoding is already in progress, which can lead to
decompression artifacts. 

The patch just checks if new caps are different than old before reopening the
decoder. I'm not sure if this is the best solution, perhaps the problem should
be dealt with on another level.
