Mans Rullgard	0aded9484d	Move dct and rdft definitions to separate files This leaves fft.h with only the core FFT and MDCT definitions thus making it more managable. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	2912e87a6c	Replace FFmpeg with Libav in licence headers Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	0b32da90f8	ARM: VP8: fix build on systems with global symbol prefix Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	8b454c352f	ARM: fix vp8 neon with pic enabled The assembler emits literal pools too far from the load instructions, so we must do it explicitly at a suitable location. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Loren Merritt	e6b1ed693a	FFT: factor a shuffle out of the inner loop and merge it into fft_permute. 6% faster SSE FFT on Conroe, 2.5% on Penryn. Signed-off-by: Janne Grunau <janne-ffmpeg@jannau.net>	14 years ago
Mans Rullgard	a7878c9f73	VP8: ARM optimised decode_block_coeffs_internal Approximately 5% faster on Cortex-A8. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	7da48fd011	ARM optimised vp56_rac_get_prob() Approximately 3% faster on Cortex-A8. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	a1c1d3c003	VP8: ARM NEON optimisations for dsp functions This adds NEON optimised versions of all functions in VP8DSPContext. Based on initial work by Rob Clark. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	b9a639ddd6	ARM: add helper macro for declaring constant data Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
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
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
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
Mans Rullgard	0745116c10	ARM: update MpegEncContext offsets	14 years ago
Mans Rullgard	78f318be59	ARM: NEON: fix overflow in h264 16x16 planar pred Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Justin Ruggles	6eabb0d3ad	Change DSPContext.vector_fmul() from dst=dstsrc to dest=src0src1. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Justin Ruggles	56f8952b25	Move lpc_compute_autocorr() from DSPContext to a new struct LPCContext. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Janne Grunau	2c3589bfda	consolidate .gitignore patters into a single file Signed-off-by: Janne Grunau <janne-ffmpeg@jannau.net>	14 years ago

Luca Barbato	183cdf7163	Update asm offsets for arm This unbreak ffmpeg build on arm/elf, arm/mach-o still need an update Originally committed as revision 26286 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Måns Rullgård	75c490f467	ARM: disable movw/movt for relocated values on Apple platforms Apparently Apple platforms do not handle movw/movt relocations properly, leading to runtime crashes in code using them. Originally committed as revision 25150 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Måns Rullgård	4a6cc8fa25	ARM: fix NEON h264_idct_add8 Originally committed as revision 25121 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago

Stefano Sabatini	c6c98d0897	Move mm_support() from libavcodec to libavutil, make it a public function and rename it to av_get_cpu_flags(). Originally committed as revision 25076 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Stefano Sabatini	7160bb716b	Rename FF_MM_ symbols related to CPU features flags as AV_CPU_FLAG_ symbols, and move them from libavcodec/avcodec.h to libavutil/cpu.h. Originally committed as revision 25040 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Måns Rullgård	94f8b2d799	ARM: update struct offsets Originally committed as revision 24923 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Måns Rullgård	c0ec9918b0	Remove global mm_flags variable Originally committed as revision 24909 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Jason Garrett-Glaser	4a384de5b8	Split h264dsp and h264pred in configure. Many H.264 derivatives, like RV40 and VP8, use the H.264 prediction functions but not the weight/loopfilter functions. This should reduce the size of builds with one of these derivatives but without H.264 decoding itself. Originally committed as revision 24741 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago

Måns Rullgård	278caa6ad3	ARM: set section to .text in 'function' macro This ensures code always goes into the .text section and avoids the need to specify it explicitly after changing sections. Originally committed as revision 24095 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	108ac7f290	ARM: hide a .size directive on non-ELF targets Originally committed as revision 24094 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Måns Rullgård	f30d51d74f	ARM: fix build with TI compiler The TI compiler defines __eabi__ to signal that ARM EABI is in use. We must check for this in addition to the gcc macro __ARM_EABI__. Originally committed as revision 23804 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Ronald S. Bultje	a815602aa3	Reindent after r23716. Originally committed as revision 23717 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
David Conrad	3ad289fca7	Add intra prediction functions for VP8. Patch by David Conrad <lessen42 gmail com> and myself. Originally committed as revision 23716 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Måns Rullgård	68dacb4e3b	ARM: check struct offsets only when they are used The offsets differ depending on configuration, so only check them when they will actually be used. Presently, this is when NEON is enabled. Originally committed as revision 23436 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
