Michael Niedermayer	9bf3fdcd3c	avcodec/h264_slice: Move h264_init_ps() call into h264_field_start() This was missing from `f512e4a390` Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago
Michael Niedermayer	fd1588919d	avcodec/h264: remove list_count and ref_count clearing The code conflicts with moving the h264_init_ps() call point Without this, ff_h264_parse_ref_count() fills ref and list count and h264_init_ps() subsequently wipes them out on a "success" path. Subsequently things crash as the wiped fields are used. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago

Aman Gupta	a49ed9e32d	avcodec/ccaption_dec: default rollup to row 10 This ensures that captions are written towards the bottom of the screen when tuning into mid-stream. The row will be reset on the receipt of the next PAC command. Row 10 was chosen as it corresponds to the value of "0" in a PAC (see row_map in handle_pac()).

Rostislav Pehlivanov	f41e37b84f	dirac_vlc: prevent shifting a 0 by 64 bits when zeroing residue Adding a check for bits == 0 would still make Coverity misdetect this, so just revert to the normal way of setting the residue to 0. Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>	9 years ago
Rostislav Pehlivanov	c4adcff976	dirac_vlc: add a SET_RESIDUE macro and fix recent regression Can also be used in future cleanups since 99% of the time the leftover appending will just append to an already empty residue. Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>	9 years ago

Rostislav Pehlivanov	0eb0f93109	diracdec: implement a LUT-based Golomb code parser Still much left to optimize, but it provides a significant performance improvement - 10% for 300Mbps (1080p30), 25% for 1.5Gbps (4k 60fps) in comparison with the default implementation.

Rostislav Pehlivanov	c43485f707	diracdec: rewrite HQ slice decoding Now coefficients are written to a buffer and are then dequantized by the new SIMD dequantization functions. For the lower bands without enough coefficients to fill a register (and hence they overwrite) the C version of the dequantization function is used. The buffer is per-thread and will be realloc'd if anything changes. This prevents regressions and having to limit slice size. Signed-off-by: Rostislav Pehlivanov <rpehlivanov@obe.tv>	9 years ago
Rostislav Pehlivanov	09d89d9406	diractab: expose the maximum quantization index as a macro Prevents having to have random magic values in the decoder and a separate macro in the encoder. Signed-off-by: Rostislav Pehlivanov <rpehlivanov@obe.tv>	9 years ago
