FYI the attached image is in JPEG2000 format, it will open in Photoshop.

ffmbc does not support j2c

To my understanding

ffmbc without libopenjpeg does not JPEG2000.
But ffmbc can support JPEG2000 when it is compiled with --enable-libopenjpeg
In my case, I have compiled with the above option.

In the attachment '2-intended command', it actually works. It take j2c and
it become a MOV file:
ffmbc -v 3 -r 24000/1001 -f image2 -vcodec libopenjpeg -i
V1-0001_P1160144.00102984.j2c -vcodec dnxhd -vb 175M -vf scale="1920:1080"
-pix_fmt yuv422p10le -r 24000/1001 ffmbc-dnxhd.mov


For the problem segfault command:

ffmbc -v 3 -f image2 -i V1-0001_P1160144.00102984.j2c -vcodec dnxhd -vb
175M -vf scale=-1:1080 test.mov

-vcodec libopenjpeg is not provided, so I think ffmbc do not know the
source image is in jpeg2000 format.

ffmbc -v 3 -f image2 -vcodec libopenjpeg -i V1-0001_P1160144.00102984.j2c
Should work with 0.7.2
