Thanks, Vincent! I am still seeing some issues:

So, here is the status of this bug now:

1)  

gst-launch-1.0 -v filesrc location=some.jp2 ! decodebin ! imagefreeze !
autovideosink

coredumps


2)  gst-launch-1.0 -v filesrc location=some.jp2 ! typefind ! jpeg2000parse !
openjpegdec ! imagefreeze ! autovideosink

Errors with  "jpeg2000parse: unable to get current caps.


3) gst-launch-1.0 -v filesrc location=some.j2k ! typefind ! openjpegdec !
imagefreeze ! autovideosink

Errors with "Could not determine type of stream".


4) Take the following ppm file:

https://github.com/GrokImageCompression/grok-test-data/blob/master/input/nonregression/Bretagne1.ppm

and compress it to jp2 using the following command line:

$ opj_compress -i Bretagn1.ppm -o Bretagne1.jp2 -OutFor jp2


Now run:


 gst-launch-1.0 -v filesrc location=Bretagne1.jp2 ! typefind ! openjpegdec !
imagefreeze ! autovideosink


The image does display, but there are severe artifacts in the image: vertical
black lines.


I'm really opening up a can of worms here :)  Thanks for your help on this,
appreciate it.
