2016-01-21diracdec: add support for 12 bit videosRostislav Pehlivanov
The DSP lacked a function needed to convert signed to unsigned. This was ignored when originally adding support and templating for bit depths greater than 8. The 10 bit function was used for 12 bit pictures and resulted in an improper conversion. Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>
