Diego Biurrun	b2bed9325d	cosmetics: Group .name and .long_name together in codec/format declarations	11 years ago
Diego Biurrun	6fee1b90ce	avcodec: Add av_cold attributes to init functions missing them	12 years ago
Anton Khirnov	f073b1500e	lavc: remove disabled FF_API_OLD_ENCODE_AUDIO cruft	12 years ago
Justin Ruggles	205a95f7b5	wmaenc: alloc/free coded_frame instead of keeping it in the WMACodecContext	12 years ago
Ronald S. Bultje	42d3246948	floatdsp: move vector_fmul_reverse from dsputil to avfloatdsp. Now, nellymoserenc and aacenc no longer depends on dsputil. Independent of this patch, wmaprodec also does not depend on dsputil, so I removed it from there also.	12 years ago
Justin Ruggles	284ea790d8	dsputil: move vector_fmul_scalar() to AVFloatDSPContext in libavutil	12 years ago
Justin Ruggles	2ed40608e9	wma: do not keep private copies of some AVCodecContext fields channels, sample_rate, bit_rate, and block_align can be used directly from the AVCodecContext	12 years ago
Justin Ruggles	31b2262dca	wmaenc: use float planar sample format	12 years ago
Diego Biurrun	6f6b0311a3	avcodec: Drop some silly commented-out av_log() invocations	12 years ago
Anton Khirnov	36ef5369ee	Replace all CODEC_ID_* with AV_CODEC_ID_*	13 years ago
Martin Storsjö	00c3b67b8a	cosmetics: Align codec declarations Also break some long lines, remove codec function placeholder comments and add spaces in sample/pixel format lists. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Justin Ruggles	27bacfeb57	wmaenc: use AVCodec.encode2()	13 years ago
Justin Ruggles	c3da9f5060	wmaenc: remove bit-exact hack It may have improved cross-platform stability, but wasn't the only place in the encoder with bitexact issues. It is no longer needed because we have FATE tests for float encoders using fuzzy comparison.	13 years ago
Justin Ruggles	51ddf35c90	wmaenc: fix m/s stereo encoding for the first frame We need to set ms_stereo in encode_init() in order to avoid incorrectly encoding the first frame as non-m/s while flagging it as m/s. Fixes an uncomfortable pop in the left channel at the start of playback. CC:libav-stable@libav.org	13 years ago
Justin Ruggles	8ed7488ea3	wmaenc: return s->block_align instead of recalculating it	13 years ago
Justin Ruggles	5d652e063b	wmaenc: check final frame size against output packet size Currently we have an assert() that prevents the frame from being too large, but it is more user-friendly to give an error message instead of aborting on assert(). This condition is quite unlikely due to the minimum bit rate check in encode_init(), but it is still worth having.	13 years ago
Justin Ruggles	dfc4fdedf8	wmaenc: require a large enough output buffer to prevent overwrites The maximum theoretical frame size is around 17000 bytes. Although in practice it will generally be much smaller, we require a larger buffer just to be safe. CC: libav-stable@libav.org	13 years ago
Justin Ruggles	1ec075cfec	wmaenc: limit allowed sample rate to 48kHz ff_wma_init() allows up to 50kHz, but this generates an exponent band size table that requires 65 bands. The code assumes 25 bands in many places, and using sample rates higher than 48kHz will lead to buffer overwrites. CC:libav-stable@libav.org	13 years ago
Justin Ruggles	c2b8dea182	wmaenc: limit block_align to MAX_CODED_SUPERFRAME_SIZE This is near the theoretical limit for wma frame size and is the most that our decoder can handle. Allowing higher bit rates will just end up padding each frame with empty bytes. Fixes invalid writes for avconv when using very high bit rates. CC:libav-stable@libav.org	13 years ago
Anton Khirnov	9f51c682ee	lavc: use avpriv_ prefix for ff_copy_bits and align_put_bits. They are used in lavf.	13 years ago
Diego Biurrun	8671488799	Use explicit struct initializers for AVCodec declarations.	13 years ago
Tomas Härdin	ee81e76db1	wmaenc: improve channel count and bitrate error handling in encode_init() Signed-off-by: Michael Niedermayer <michaelni@gmx.at> Signed-off-by: Anton Khirnov <anton@khirnov.net>	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	2912e87a6c	Replace FFmpeg with Libav in licence headers Signed-off-by: Mans Rullgard <mans@mansr.com>	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
Stefano Sabatini	5d6e4c160a	Replace deprecated symbols SAMPLE_FMT_* with AV_SAMPLE_FMT_*, and enum SampleFormat with AVSampleFormat. Originally committed as revision 25730 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Reimar Döffinger	edac49daf5	Use "const" qualifier for pointers that point to input data of audio encoders. This is purely for clarity/documentation purposes. Originally committed as revision 24481 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Stefano Sabatini	72415b2adb	Define AVMediaType enum, and use it instead of enum CodecType, which is deprecated and will be dropped at the next major bump. Originally committed as revision 22735 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Stefan Gehrer	3a201bd04f	remove a Huffman table from WMA which also exists in AAC Originally committed as revision 21902 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	b5f09d31c2	Make sample_fmts and channel_layouts compound literals const to reduce size of .data section. Originally committed as revision 19787 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Sascha Sommer	9970c61b4b	Introduce WMACoef typedef for decoded coefficients and change default type to float so that the run level decoding functionality can be shared with wmapro Originally committed as revision 19231 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Siarhei Siamashka	7d485f165f	Support for getting (i)MDCT output multiplied by a constant scaling factor. Scaling (i)MDCT output has no runtime overhead and can be used to improve performance of audio codecs. All the changes are only needed in 'ff_mdct_init' function and slow down initialization a bit. Originally committed as revision 18855 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Stefano Sabatini	fb53b4a035	Rename pbBufPtr() to put_bits_ptr(). The new name is more readable and consistent with the FFmpeg naming style. Originally committed as revision 18497 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

Diego Pettenò	2d5174fc46	Intel C compiler warns on this assignment in this if(), probably because it's being assigned as a constant. To avoid a spurious warning, split it into two instructions, which should also make it more logical once the FIXME is resolved. patch by Diego 'Flameeyes' Pettenò %flameeyes A gmail P com% Originally committed as revision 15525 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
