| | | | | | | These fields are only used in quantize_mantissas() and reset on each call, no need to store them in the main context. Signed-off-by: Mans Rullgard <mans@mansr.com>

* Detect byte-swapped AC-3 and support decoding it directly.Reimar Döffinger2011-03-221-0/+5
| | | | | | | 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.
* cosmetics: indentationJustin Ruggles2011-03-221-3/+3

* Always copy input data for AC3 decoder.Justin Ruggles2011-03-221-7/+2
| | | | | | | 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>

* vc1: slice support.Ronald S. Bultje2011-03-211-24/+57
| | | | Also reset coded_block at each new slice, fixes problems in slice playback.
* vc1: fix up memleaks in the error codepath.Ronald S. Bultje2011-03-211-22/+19
| | | | | Introduce end: and err: labels at the end of vc1_decode_frame(), which will clean up allocated memory consistently.
* vc1: warn for unimplemented pan-scan feature.Ronald S. Bultje2011-03-211-0/+1

* ffv1: allocate correct size for sample bufferMans Rullgard2011-03-201-1/+1
| | | | | | | This fixes a typo in the size calculation for the sample buffer introduced in cbabccc367424. Signed-off-by: Mans Rullgard <mans@mansr.com>
* Move ff_dct_init_mmx declaration to dct.hMans Rullgard2011-03-202-1/+2

* Move dct and rdft definitions to separate filesMans Rullgard2011-03-2013-72/+138
| | | | | | | 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>
* Move sine windows to a separate fileMans Rullgard2011-03-2018-33/+98
| | | | | | | 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>
* Move ff_kbd_window_init() to a separate fileMans Rullgard2011-03-199-41/+90
| | | | | | | 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>
* fft: remove inline wrappers for function pointersMans Rullgard2011-03-1927-109/+80
| | | | | | | 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>
* Remove Sonic experimental audio codecMans Rullgard2011-03-193-982/+0
| | | | | | | | 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>

* aacenc: 10l, missed a reference when refactoring the psymodel.Nathan Caldwell2011-03-171-1/+1

* ac3enc: add float_to_fixed24() with x86-optimized versions to AC3DSPContextJustin Ruggles2011-03-176-9/+166
| | | | and use in scale_coefficients() for the floating-point AC-3 encoder.
* aacenc: cosmetics, indentation, and comment clarificationNathan Caldwell2011-03-162-34/+37
| | | | | Correct bad indentation in aaccoder Clarify and correct comments in 3GPP psymodel, other cosmetics.
* aacenc: Refactor the parts of the AAC psymodel.Nathan Caldwell2011-03-161-40/+37
| | | | | | | | | | | 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.

* dsputil: add bswap16_buf()Mans Rullgard2011-03-162-0/+8
| | | | | | | | 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>
* use LIBAV_LICENSE and LIBAV_VERSION instead of FFMPEG_*Janne Grunau2011-03-161-1/+1

| | | | also update the multiple inclusion guards in config.h|mak
* mathops: fix MULL() when the compiler does not inline the function.Justin Ruggles2011-03-151-1/+1
| | | | | | | 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.
