Nathan Caldwell	4afedfd8e5	aacenc: cosmetics, indentation, and comment clarification Correct bad indentation in aaccoder Clarify and correct comments in 3GPP psymodel, other cosmetics.	14 years ago
Nathan Caldwell	b7c96769c5	aacenc: Refactor the parts of the AAC psymodel. 3GPP: Remove ffac from and move min_snr out of AacPsyBand. Rearrange AacPsyCoeffs to make it easier to implement energy spreading. Rename the band[] array to bands[] Copy energies and thresholds at the end of analysis. LAME: Use a loop instead of an if chain in LAME windowing.	14 years ago
Young Han Lee	f578854efc	aaccoder: Change FFMAX for allzero flag to OR bit operation Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago

Mans Rullgard	381d37fda9	dsputil: add bswap16_buf() There are several places where a buffer is byte-swapped in 16-bit units. This allows them to share code which can be optimised for various architectures. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Janne Grunau	a03be6e1ba	use LIBAV_LICENSE and LIBAV_VERSION instead of FFMPEG_*	14 years ago
Janne Grunau	29ba091136	replace FFMPEG with LIBAV in FFMPEG_CONFIGURATION also update the multiple inclusion guards in config.h\|mak	14 years ago
Justin Ruggles	79414257e2	mathops: fix MULL() when the compiler does not inline the function. If the function is not inlined, an immmediate cannot be used for the shift parameter, so the %cl register must be used instead in that case. This fixes compilation for x86-32 using gcc with --disable-optimizations.	14 years ago
Justin Ruggles	aaff3b312e	mathops: change "g" constraint to "rm" in x86-32 version of MUL64(). The 1-arg imul instruction cannot take an immediate argument, only a register or memory argument.	14 years ago
Justin Ruggles	b181b8fb96	mathops: convert MULL/MULH/MUL64 to inline functions rather than macros. This fixes unexpected name collisions that were occurring with variables declared within the macros. It also fixes the fate-acodec-ac3_fixed regression test on x86-32.	14 years ago
Philip Langdale	025225d7ee	h264_mp4toannexb_bsf: Fix spurious warning when stream has SPS and PPS units. Signed-off-by: Philip Langdale <philipl@overt.org> Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Justin Ruggles	f1efbca5e9	ac3enc: add SIMD-optimized shifting functions for use with the fixed-point AC3 encoder.	14 years ago
Justin	323e6fead0	ac3enc: do not right-shift fixed-point coefficients in the final MDCT stage. This increases the accuracy of coefficients, leading to improved quality. Rescaling of the coefficients to full 25-bit accuracy is done rather than offsetting the exponent values. This requires coefficient scaling to be done before determining the rematrixing strategy. Also, the rematrixing strategy calculation must use 64-bit math to prevent overflow due to the higher precision coefficients.	14 years ago
Peter Ross	6e7cf13b6b	mm decoder: move buffer allocation from decode_init() to decode_frame() This permits playback in ffplay when libavfilter is enabled. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago

Jason Garrett-Glaser	81a131312d	VP8: fix other function declaration Was missed in `3efbe137`.	14 years ago
Hendrik Leppkes	0215006ab7	VC1: Export profile/level Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Jason Garrett-Glaser	1eeca88691	VP8: optimize VP8Context struct ordering Shaves at least 3KB off code size on x86, should improve cache utilization. This would probably be useful to do for other decoders/encoders as well.	14 years ago
Jason Garrett-Glaser	3efbe13739	VP8: fix function declaration	14 years ago
Jason Garrett-Glaser	b1d2f812c9	VP8: token probs doesn't need padding prob[0] is the only prob array ever accessed, so prob[1] can serve as padding for prob[0].	14 years ago
Jason Garrett-Glaser	628b48db85	VP8: use a goto to break out of two loops A break statement was supposed to break out of two loops, but only broke out of one. Didn't affect output, just could have been marginally slower.	14 years ago
Mans Rullgard	a5444fee06	Add CONFIG_AC3DSP symbol to simplify makefiles Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago

Nathan Caldwell	31ff9bd7b8	aacenc: Fix a segfault in search_for_quantizers This reverts the removal of scoefs from AACEncContext. It resulted in scoefs being a NULL pointer when search_for_quantizers() is called. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Ronald S. Bultje	4e84f994d3	reindent.	14 years ago
Young Han Lee	2790d7a9ff	aacenc: remove the data arrays Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Thadeu Lima de Souza Cascardo	36864ac354	aac_latm_dec: use aac context and aac m4ac When decoding latm config, use the corresponding aac context and its m4ac instead of using NULL and a local variable. This fixes decoding of audio in MPEG TS from SBTVD (the Brazillian Digital TV Sytem), when there is no extradata. This is the case when using the decoder with gst-ffmpeg and a GStreamer mpegts demuxer. Signed-off-by: Thadeu Lima de Souza Cascardo <cascardo@holoscopio.com> Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Justin Ruggles	2d9a101a1f	ac3enc: add some assertions	14 years ago
Justin Ruggles	7100d63ca5	ac3enc: use av_assert2() instead of assert() to make debugging easier.	14 years ago
Justin Ruggles	d21be5f15b	cosmetics: rename ff_fmt_convert_init_ppc() to ff_fmt_convert_init_altivec(). It only has Altivec functions and is not compiled if Altivec is disabled.	14 years ago
Carl Eugen Hoyos	159683ddec	Fix compilation on powerpc with --disable-altivec.	14 years ago
Sean McGovern	02dd3666c2	h264_mp3toannexb_bsg: don't crash, but warn, if PPS/SPS not found. Should an AVC-1 in MP4 stream not contain SPS or PPS NAL units, this BSF is then unable to allocate an output buffer for the modified stream. Warn that the resulting stream may be unplayable. Fix roundup issue #2386. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Justin Ruggles	53e35fd340	ac3enc: add num_rematrixing_bands to AC3EncodeContext and use it instead of the hardcoded value. Currently it is always 4, but this change will allow it to be adjusted when bandwidth-related features are added such as channel coupling, enhanced channel coupling, and spectral extension.	14 years ago
Justin Ruggles	b35743ffb4	ac3: define AC3_MAX_CPL_BANDS and use it in ac3dec.h	14 years ago
Ronald S. Bultje	8cf9a09d40	vp3-mt: fix deadlock when first frame is not a keyframe.	14 years ago
Mans Rullgard	ff1efc524c	threads: allow thread count of zero This moves setting the thread count to a minimum of 1 to frame_thread_init(), allowing a value of zero to propagate through to the codec if frame threading is not used. This makes auto-threads work in libx264. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago

Alexander Strange	76d8846c4e	huffyuv: Add multithreading support Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Alexander Strange	ad9791e12b	pthreads: Fix bug introduced with thread_safe_callbacks For intra codecs, ff_thread_finish_setup() is called before decoding starts automatically. However, get_buffer can only be used before it's called, so adding this requirement broke frame threading for them. Fixed by moving the call until after get_buffer is finished.
