Thanks. Are there any work flows that you know of involving jpeg 2000 that
involve jp2 files ? j2c and j2k indicate pure code stream files, while jp2 
use jpeg 2000 file format, which includes the "colour" box that can be used
to infer the sampling field.

openjpegenc only produces j2c streams, but it does set the sampling field, in
my patches. 

For j2c and j2k streams that do not involve openjpegenc plugin, it will not 
be possible to figure out the sampling field.

To test this, I do need a jp2 work flow.

Also, do you know of any users who are using gstreamer for jpeg 2000 streaming?
Would like to get them involved.
