Checksum error when referencing POC's farther than 16 pics away

[ari-koivula]

Example: -i BasketballDrive_1920x1080_50_500.yuv -otest.265 -n32 --preset=ultrafast -p32 --gop=lp-g16d3t1 -r2 --no-tmvp

POC 16 refers to POC 0 without problem, but POC 17 only refers to POC 0 only once, and get's a checksum error on it. This probably means that Kvazaar uses a wrong reference for POC 0 when encoding POC 17.

Quite likely to happen eventually with lp-gop, when either number of references and size of GOP allow references farther than 16 away.

Another example: -iBasketballDrive_1920x1080_50_500.yuv -oout.hevc -p32 --wpp --preset=ultrafast -r5 -q27 --no-tmvp
