Sebastian, you were right about inadvisability of setting caps after parsing
the stream. When I do this, and pass in an RGB test signal, the output seems to
switch sYUV. 

I will create a new element that will pull from stream and set in caps for
payloader to read.

Since I have added the sampling field in our  OpenJPEG encoder, this new
element should be a no-op if gstreamer is producing the jpeg 2000 stream. 

If another server streams JPC video to gstreamer, then we will have to parse
the stream twice. I guess it shouldn't be a big deal.
