Ari Koivula 5f75753f85 Set coeff flags correctly.
The coeff flags are no longer propagated upwards because encode_transform_tree

array when the coeff flag is set.

Ari Koivula 5760c79272 Fix crash with dimensions that are not multiples of 8.
The clean up of input parsing and encoder initialization code had caused the
real source input dimensions to be used for array initialization, instead of
the dimensions modified to be multiples of the smallest coding unit.
2014-02-21 12:48:33 +02:00

complicated stuff, like building the project on command line with
Visual Studio.
2014-02-19 16:58:52 +02:00

2014-02-19 14:36:17 +02:00
Marko Viitanen 3618eab72a Added lambda cost when using reference frames with refIdx > 0
Because selecting references "far away" costs bits, this should help with the issue that multiple reference frames actually increases coded bits with no quality gain.
2014-02-19 14:34:36 +02:00
Marko Viitanen 478552ea00 Added commandline parameter for reference frame number

Ari Koivula 8e63dd29bb Fix compiler warnings for VS2010 /W4 in intra.c.
- Working towards issue #11.
- Removed intra_get_block_mode as unused.
- Removed unused parameters from functions. Many of them were remnants from
  earlier data structures and earlier features of HEVC that have been removed.
- Lots of implicit conversions from larger types to smaller ones. I tried to
  avoid turning all of them to explicit ones this time and opted for changing
  the original data type instead. Had to do it in few cases though to stop the
  changes from propagating too widely.
