Vitor Sessak	ee26abf2a4	Fix an infinite loop when RoQ encoded generated a frame with a size greater than the maximum valid size. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Kieran Kunhya	a6d2227bc8	Add kbdwin.o to AC3 decoder Fixes --disable-everything --enable-decoder=ac3 Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Reimar Döffinger	4c886d613d	Detect byte-swapped AC-3 and support decoding it directly. This allows the AC-3 decoder to be used directly with RealMedia decoders that unlike the libavformat one do not byte-swap automatically. Since the new code is only used in case we would fail directly otherwise there should be no risk for regressions.	14 years ago
Justin Ruggles	40728b5169	cosmetics: indentation	14 years ago
Justin Ruggles	67fc8652b9	Always copy input data for AC3 decoder. Depending on error_recognition is not correct, low values do certainly not mean it is ok to crash. Based on a patch by Reimar Döffinger <Reimar.Doeffinger@gmx.de>	14 years ago
Justin Ruggles	85ab290470	ac3enc: make sym_quant() branch-free	14 years ago
Ronald S. Bultje	c47d383502	vc1: make P-frame deblock filter bit-exact.	14 years ago
Ronald S. Bultje	f44d6445b7	vc1: slice support. Also reset coded_block at each new slice, fixes problems in slice playback.	14 years ago
Ronald S. Bultje	b81a935bd9	vc1: fix up memleaks in the error codepath. Introduce end: and err: labels at the end of vc1_decode_frame(), which will clean up allocated memory consistently.	14 years ago
Ronald S. Bultje	72452cc475	vc1: warn for unimplemented pan-scan feature.	14 years ago
Mans Rullgard	027f60f32b	ffv1: allocate correct size for sample buffer This fixes a typo in the size calculation for the sample buffer introduced in `cbabccc367`. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	e87a6f0dc9	Move ff_dct_init_mmx declaration to dct.h This was missed in `0aded94`. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	8eec00278c	dct: remove superflous #include Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
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	4538729afe	Move sine windows to a separate file These windows do not really belong in fft/mdct files and were easily confused with the similarly named tables used by rdft. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	a45fbda994	Move ff_kbd_window_init() to a separate file This function is not tightly coupled to mdct, and it's in the way of making a fixed-point mdct implementation. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	26f548bb59	fft: remove inline wrappers for function pointers This removes the rather pointless wrappers (one not even inline) for calling the fft_calc and related function pointers. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	42cfb3835b	Remove Sonic experimental audio codec Since initially committed in 2004, this codec has only been touched for maintenanance. Functionally, it contains no novel ideas and its intended audience is better served by existing mature codecs. 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
Nathan Caldwell	350785a662	aacenc: 10l, missed a reference when refactoring the psymodel.	14 years ago
Justin Ruggles	0f999cfddb	ac3enc: add float_to_fixed24() with x86-optimized versions to AC3DSPContext and use in scale_coefficients() for the floating-point AC-3 encoder.	14 years ago
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
Ramiro Polla	cbf5d22d24	Remove occurrences of my old email address Signed-off-by: Mans Rullgard <mans@mansr.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

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

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

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
