gstopenjpegdec.c
Comment 1 Aaron Boxer 2016-05-10 17:01:18 UTC 
Not going to worry about this after all.
Comment 2 Sebastian Dröge (slomo) 2016-05-15 10:09:38 UTC 
Does it make a difference, can it cause problems, what does it mean at all? :)
Comment 3 Aaron Boxer 2016-05-15 20:13:18 UTC 
JPWL refers to the jpeg 2000 wireless protocol, an extension of jpeg 2000 for transmission of j2k images over error-prone wireless networks. 

Perhaps the original implementer wanted to support JPWL.

In the interest of being minimalist, I wanted to remove it if it is not being used, but I don't think it is worth worrying about :)
Comment 4 Sebastian Dröge (slomo) 2016-05-16 10:48:46 UTC 
Does it have any effect? If so we should probably remove it or hide it behind a property
Comment 5 Aaron Boxer 2016-05-16 11:59:13 UTC 
If the openjpeg decoder is built with JPWL support, then it will need this
parameter set. Otherwise it defaults to 3, so would break for GRAYSCALE images.

If not built with JPWL, then this parameters is ignored.
