openjpeg - issue #63

16 bit mj2 run through mj2_to_frames producing 8 bit yuv

Posted on Feb 11, 2011 by Grumpy Rabbit

Using the new feature (from issue #49) I can do this: frames_to_mj2 -i 16bit.yuv -o 16bit.mj2 -W 720,486,2,1 -F 29.97 -D 16

but when I run the reverse: mj2_to_frames 16bit.mj2 back_to_16bit.yuv

it produces an 8 bit output. Can mj2_to_frames decode to non-8bit? Dave Rice avpreserve.com

Hi Dave,

A fix has been committed. Issue 49 was actually incompletely solved. 16-bit precision should work now, both at mj2 encoding and decoding.

Feedback welcome once you've tested it on your data.

Cheers,

Antonin
