Justin Ruggles	0e830094ad	samplefmt: avoid integer overflow in av_samples_get_buffer_size() CC:libav-stable@libav.org	11 years ago
Anton Khirnov	8207c67a24	lavu: remove disabled FF_API_GET_BITS_PER_SAMPLE_FMT cruft	12 years ago
Anton Khirnov	cd15b7c03d	samplefmt: make av_samples_alloc() initialize the data to silence. Right now the buffer is zeroed, which does not represent silence for U8(P).	12 years ago
Martin Storsjö	1d9c2dc89a	Don't include common.h from avutil.h Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Anton Khirnov	6d7f617700	samplefmt: add a function for filling a buffer with silence.	13 years ago
Anton Khirnov	142e740d1e	samplefmt: add a function for copying audio samples.	13 years ago
Diego Biurrun	ce473de921	av_samples_fill_array: Mark unmodified function argument as const. libavcodec/utils.c:274: warning: passing argument 3 of ‘av_samples_fill_arrays’ discards qualifiers from pointer target type ./libavutil/samplefmt.h:151: note: expected ‘uint8_t ’ but argument is of type ‘const uint8_t ’	13 years ago
Justin Ruggles	83b26046fc	avutil: change default buffer size alignment for sample buffer functions Aligning nb_samples will give both correct plane pointer alignment and enough padding for SIMD-optimized functions.	13 years ago
Justin Ruggles	0109a09dc3	avutil: use align == 0 for default alignment in audio sample buffer functions	13 years ago
Justin Ruggles	18ed3788b0	avutil: allow NULL linesize in av_samples_fill_arrays() and av_samples_alloc()	13 years ago
Justin Ruggles	4d693b023c	avutil: add av_get_packed_sample_fmt() and av_get_planar_sample_fmt() Based on a patch by Clément Bœsch <ubitux@gmail.com>	13 years ago
Justin Ruggles	bbb46f3ec7	libavutil: add utility functions to simplify allocation of audio buffers. Based on code by Stefano Sabatini.	13 years ago
Justin Ruggles	8889cc4f5b	libavutil: add planar sample formats and av_sample_fmt_is_planar()	13 years ago
Stefano Sabatini	a6703faa15	samplefmt: add av_get_bytes_per_sample() Deprecate av_get_bits_per_sample_fmt(), which was a misnamed function. For the moment we don't have sample formats with a non-integer number of bytes, in that case we may need to create a new av_get_bits_per_sample() function. In the meanwhile we prefer to adopt this variant, since avoids divisions by 8 all over the place.	14 years ago
Mans Rullgard	2912e87a6c	Replace FFmpeg with Libav in licence headers Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Reinhard Tartler	737eb5976f	Merge libavcore into libavutil It is pretty hopeless that other considerable projects will adopt libavutil alone in other projects. Projects that need small footprint are better off with more specialized libraries such as gnulib or rather just copy the necessary parts that they need. With this in mind, nobody is helped by having libavutil and libavcore split. In order to ease maintenance inside and around FFmpeg and to reduce confusion where to put common code, avcore's functionality is merged (back) to avutil.

Stefano Sabatini	6f84cd1279	Add av_get_bits_per_sample_fmt() to libavcore/samplefmt.h and deprecate av_get_bits_per_sample_format(). Originally committed as revision 25654 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Stefano Sabatini	d63e456a2a	Implement functions: av_get_sample_fmt_name() av_get_sample_fmt() av_get_sample_fmt_string() in libavcore, and deprecate the corresponding libavcodec/audioconvert.h functions: avcodec_get_sample_fmt_name() avcodec_get_sample_fmt() avcodec_sample_fmt_string() Originally committed as revision 25653 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
