*Please fill in all defect information below.*
Product Version: svn .30

/usr/obj/usr/src/sys/ARIKA amd64

2.
3.
What is the expected output?
convert to j2c
What is actual output?
no files found
Please provide any additional information below.
Apparently Adobe Premier exports frames in jpx format, i received a disk filled
with 250k jpx files. Adding 'jpx' to decoder extensions works, the file is
converted.
ie, opendcp_decoder.h:22:
OPENDCP_DECODER(OPENDCP_DECODER_OPENJPEG, openjpeg, "jpx;j2c;j2k;jp2;jpf", 1)
FYI size comparison
906K Apr 3 00:47 2000181581.j2c
5.7M Apr 3 00:48 2000181581.jpx
Thank you

After further research it seems this issue should be changed to 'Priority-Low'
and 'Type-Enhancement'. The plugin in Premiere uses Kakadu-v6.3.1 to create a
lossless j2k image. However, there seem to be some issues reading / converting
the image depending on the version of openjpeg. v1.3.0 seems to convert without
issue, however I have found some bug reports regarding jpx images with this
version. v1.5.0 and v1.5.2 return invalid format errors and will not convert
the jpx.

Ok, if it's issue with OpenJPEG, there there isnt much that can be done until
it gets fixed upstream.
