Nicolas George	62ecd3635a	Set pkt_pts in avcodec_default_reget_buffer() This was missed when pkt_pts was first added. Signed-off-by: Nicolas George <nicolas.george@normalesup.org> Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Justin Ruggles	c3beafa0f1	ac3enc: Change EXP_DIFF_THRESHOLD to 500. This patch changes the exponent difference threshold in the exponent strategy decision function of the AC-3 encoder. I tested lowering in increments of 100. From 1000 down to 500 generally increased in quality with each step, but 400 was generally much worse.

Justin Ruggles	c73d99e672	Separate format conversion DSP functions from DSPContext. This will be beneficial for use with the audio conversion API without requiring it to depend on all of dsputil. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Alex Converse	770c410fbb	Fix ff_imdct_calc_sse() on gcc-4.6 Gcc 4.6 only preserves the first value when using an array with an "m" constraint. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago

Jason Garrett-Glaser	64233e702a	VP8: merge chroma MC calls Adds some duplicated code, but avoids duplicate edge checks and similar. ~0.5% faster overall on Parkjoy test sample.	14 years ago
Ronald S. Bultje	81f2a3f4ff	Implement a SIMD version of emulated_edge_mc() for x86. From ~550 cycles (C version) to 170 (SSE/x86-64), 206 (MMX/x86-32) and 196 (SSE2/x86-32) cycles.	14 years ago
Justin Ruggles	d19b744a36	cosmetics: indentation Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Justin Ruggles	80ba1ddb58	Remove unneeded add bias from 3 functions. DSPContext.vector_fmul_window() DCADSPContext.lfe_fir() SynthFilterContext.synth_filter_float() Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Jason Garrett-Glaser	73be29b0c4	Slightly simplify VP8 inter_predict Merge an if and a switch.	14 years ago
Luca Barbato	dfd2a005eb	Replace dprintf with av_dlog dprintf clashes with POSIX.1-2008	14 years ago
Justin Ruggles	243f8241db	Flush final frames in libfaac encoder. Gives decoded output identical in length to faac commandline encoder. Fixes Issue 670. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Vitor Sessak	e0eb963aaa	Fix memory leak in ALS decoder in big endian systems Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	d461a47317	Rearrange MpegEncContext to simplify access from asm This moves the fields needed by asm near the top, before any structs or other members which complicate the offset calculation. Modifying other structs will no longer require updating the offsets, and the asm code is slightly simpler due to the smaller offsets. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Vitor Sessak	3af1fe829e	Fix overread in altivec DSP function sad16 Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	0745116c10	ARM: update MpegEncContext offsets	14 years ago
Ronald S. Bultje	2e27959879	Move ff_emulated_edge_mc() into DSPContext.	14 years ago
Ronald S. Bultje	e5262ec44a	Optimize C version of ff_emulated_edge_mc(). From ~780 cycles to 551 cycles, mostly just by using libc memcpy() instead of manually shuffling individual bytes around.	14 years ago
Alex Converse	e5c82df80e	aacdec: Convert some loop copies into memcpy()s. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Stefano Sabatini	3c802cabba	In the rawvideo decoder, set pkt_pts in the output frame. Signed-off-by: Janne Grunau <janne-ffmpeg@jannau.net>	14 years ago
Ronald S. Bultje	9d4bdcb714	Fix VP8 aliasing problems. Replace * (uint32_t *) buf accesses with AV_WN32A/AV_COPY32.	14 years ago
Alex Converse	5ce5dbc5f3	Make ff_float_to_int16*_c() static. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Diego Elio Pettenò	ac28ce5fac	Hide the now-prefixed decoders, encoders, parsers, bsf, hwaccel objects. This significantly reduces the size of the symbol table in the generated ELF shared object (as well as the other linked tables). Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Justin Ruggles	b5ec638343	cosmetics: indentation and spacing	14 years ago
Justin Ruggles	9d06d7bce3	Remove the add bias hack for the C version of DSPContext.float_to_int16_*().	14 years ago
Justin Ruggles	37cb3eb534	Add special case for 2nd-order IIR filter. 40% faster in ff_iir_filter_flt() when c->order == 2.	14 years ago
Luca Barbato	d1b6f33bf2	Add ff_ to AVHWAccel decoders That unbreaks compilation of vaapi and dxva2 Signed-off-by: Janne Grunau <janne-ffmpeg@jannau.net>	14 years ago
Ronald S. Bultje	22893e10ae	VP8: don't overread edges on fourtap MC. Fix C VP8 H+V MC functions which do two-dimensional 4/6-tap filters to not overread beyond their edges if the second filter is 4-tap, since the outer pixels aren't there anymore since `44002d8323`.	14 years ago
Diego Elio Pettenò	d36beb3f69	Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf. None of these symbols should be accessed directly, so declare them as hidden. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Diego Elio Pettenò	2d162e3825	Make ff_cmap_read_palette static to libavcodec/iff.c. Delete iff.h. The iff.h header only declared one function that is now static, the libavformat/iff.c source file wasn't using it before. Drop the file entirely. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Justin Ruggles	4c57cde942	Add ff_ prefix to ac3_common_init(). Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Justin Ruggles	24e3ad3031	ac3: Remove ff_ac3_critical_band_size_tab. It is only used to generate band_start_tab, which about the same size, at runtime, so it's simpler just to always hardcode band_start_tab. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Diego Elio Pettenò	7767d8d361	Mark C base versions of FFT functions static to fft.c Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago

Diego Elio Pettenò	13eb6b9097	Make ff_h264_find_frame_end static to h264.c; delete h264_parser.h The header is empty after making the function static, so delete it and drop its usage. Signed-off-by: Janne Grunau <janne-ffmpeg@jannau.net>	14 years ago
Diego Elio Pettenò	cf1d794a49	Make ff_ass_subtitle_header static to ass.c Signed-off-by: Janne Grunau <janne-ffmpeg@jannau.net>	14 years ago
Diego Elio Pettenò	d625a32d6b	Make ff_sin_tabs constant to rdft.c Signed-off-by: Janne Grunau <janne-ffmpeg@jannau.net>	14 years ago
