7edff6e746 jpeg2000parse: no pts interpolation with subframe. 
The jpeg2000parser must not interpolate PTS with subframes.

db13dc9d02 jpeg2000parse: support frame and stripe alignment in caps 
forward alignment and num-stripes caps properties

Use caps height when setting caps for subframe

We want downstream to use full frame height, not subframe height

969e30c035 jpeg2000parse: refactor 
1. only recalculate src codec format if sink caps change
2. use correct value for "jp2c" magic in J2C box ID
3. only parse J2K magic once, and store result
4. more sanity checks comparing caps to parsed codec

e10276a616 jpeg2000parse: initial support for JP2 format 
This is a simple way of supporting JP2 : we treat is as JPC, and throw
away header info.

2cffa1579a jpeg2000parse: allow parsing when current caps are null 
In this case, we assume that the format is jpc, and we infer the color
space from the number of components. This allows the parser to process a
jpc disk file coming from a filesrc element.

9ec2b7ce13 jpeg2000parse: parse RSIZ capabilities and put profile/level into the caps 
The RSIZ capabilities tag stores the JPEG 2000 profile. In the case of
broadcast profiles, it also stores the broadcast main level, which
specifies the bit rate.

ba22007e2f jpeg2000parse: fix negotiation with j2c and jpc both allowed upstream 
If upstream supports both, but downstream supports only jpc, j2c
would have been selected as the first in the caps.

418e643b61 gstjpeg2000parse: no need for else after a goto 
else clause is redundant when the end of the if statement is a jump.
If we haven't gone to the beach, we are in the false branch.

3dc3a915ea jpeg2000parse: Require either colorspace or sampling field in sink caps 
And always set the sampling field on the src caps, if necessary guessing a
correct value for it from the colorspace field.

Also, did some cleanup: removed sampling enum - redundant.
