*Please fill in all defect information below.*

Product Version: svn .30
GUI or CLI: cli
Operating system: FreeBSD 11.0-CURRENT #0 r263676: Sun Mar 30 23:31:37 PDT 2014 
    /usr/obj/usr/src/sys/ARIKA  amd64


What steps will reproduce the problem?
1. opendcp_j2k -i /path/to/jpx -o /out
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.
