| * golomb: Fix the implementation of get_se_golomb_longMartin Storsjö2014-03-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This was only used in hevc muxing code so far. This makes the return values match what get_se_golomb returns for the same bitstream reader instances. The logic for producing a signed golomb code out of an unsigned one was based on the corresponding code in get_se_golomb, which operated directly on the bitstream reader buffer - not on the equivalent return value from get_ue_golomb.

| * golomb: use unsigned arithmetics in svq3_get_ue_golomb()Janne Grunau2012-12-08
| | | | | | | | | | | | | | | | | | | | This prevents undefined behaviour of signed left shift if the coded value is larger than 2^31. Large values are most likely invalid and caused errors or by feeding random. Validate every use of svq3_get_ue_golomb() and changed the place there the return value was compared with negative numbers. dirac.c was clean, fixed rv30 and svq3.

| | | | | | | | | | | | | | | | | | | | The bit_rate_value_minus1 and cpb_size_value_minus1 elements allow a wider range than get_ue_golomb() supports. This adds a get_ue_golomb_long() function supporting up to 31 leading zeros, which is the maximum for these syntax elements, and uses it in decode_hrd_parameters().
