|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * qatar/master: ALPHA: Replace sized int_fast integer types with plain int/unsigned. Duplicate DPX image encoder Duplicate DPX decoder: read sample aspect ratio Duplciate DPX decoder: add buffer size checks. ac3enc: clip large coefficient values and negative exponents rather than using av_assert2(). ac3enc: do not store a bandwidth code for each channel. ac3enc: remove bandwidth reduction as fallback for bit allocation failure. ac3enc: merge compute_exp_strategy_ch() into compute_exp_strategy() ac3enc: return error if frame+exponent bits are too large instead of using av_assert2(). ac3enc: differentiate between current block and reference block in bit_alloc() ac3enc: simplify exponent_init() by calculating exponent_group_tab[] based on exponent group sizes. ac3enc: simplify stereo rematrixing decision options Include both URLs: Update URL to fate samples Conflicts: Changelog doc/fate.txt libavcodec/ac3enc.c libavcodec/dpxenc.c libavcodec/version.h Merged-by: Michael Niedermayer <michaelni@gmx.at>
