Clément Bœsch	81a65b82fb	swr: handle correctly muted channel with u8 sample fmt.	13 years ago
Clément Bœsch	fc6351d019	swr: make audio convert code explicitely private. Only what's declared in libswresample/swresample.h is public.	13 years ago
Clément Bœsch	fc42550097	swr: move format convert code to dedicated functions. This should easier common case optimizations.	13 years ago
Clément Bœsch	f5cd136f2b	ffmpeg: add -map_channel option. Based on an initial work by Baptiste Coudurier.	13 years ago
Michael Niedermayer	b5875b9111	Add libswresample. Similar to libswscale this does resampling and format convertion, just for audio instead of video. changing sampling rate, sample formats, channel layouts and sample packing all in one with a very simple public interface. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Alex Converse	2f072b55a4	Fix the conversion of AV_SAMPLE_FMT_FLT and _DBL to AV_SAMPLE_FMT_S32. (1<<31) is undefined and seems to be evaluated by gcc to -2^31 when these formulae require 2^31. These conversions still need fate tests.	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	7ffe76e540	Merge libavcore into libavutil Done to keep ABI compatible. Otherwise this is just silly	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	63e8d9760f	Use the new libavcore audio channel API. This also allows to remove a linking dependency of libavfilter on libavcodec. Originally committed as revision 25789 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Stefano Sabatini	176a6157c0	Move audio channel API from libavcodec to libavcore. Originally committed as revision 25787 to svn://svn.ffmpeg.org/ffmpeg/trunk	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
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

Diego Biurrun	ba87f0801d	Remove explicit filename from Doxygen @file commands. Passing an explicit filename to this command is only necessary if the documentation in the @file block refers to a file different from the one the block resides in. Originally committed as revision 22921 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Justin Ruggles	0fb6a8b339	Remove the 3-front-channel layout from the list of channel layout aliases. Calling this "surround" is confusing and questionable. Originally committed as revision 19183 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Justin Ruggles	be233a5691	Check that channel layout is compatible with number of channels for output audio stream. Originally committed as revision 18621 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

Diego Biurrun	bad5537e2c	Use full internal pathname in doxygen @file directives. Otherwise doxygen complains about ambiguous filenames when files exist under the same name in different subdirectories. Originally committed as revision 16912 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
