James Almer	9ea6d2149e	avcodec/decode: add a flags parameter to ff_reget_buffer() Some decoders may not need a writable buffer in some specific cases, but only a reference to the existing buffer with updated frame properties instead, for the purpose of returning duplicate frames. For this, the FF_REGET_BUFFER_FLAG_READONLY flag is added, which will prevent potential allocations and buffer copies when they are not needed.

Diego Biurrun	b668662939	get_bits: Move BITSTREAM_READER_LE definition before all relevant #includes This avoids the danger that get_bits.h might get indirectly #included before BITSTREAM_READER_LE is defined. Also sort headers into canonical order where appropriate.	9 years ago

Kostya Shishkov	4cfb0d871d	tscc2: do not add/subtract 128 bias during DCT It turns out that the reference decoder subtracts 128 from DC during block decode but adds it back during reordering block with zigzag pattern.
