Andreas Rheinhardt	790f793844	avutil/common: Don't auto-include mem.h There are lots of files that don't need it: The number of object files that actually need it went down from 2011 to 884 here. Keep it for external users in order to not cause breakages. Also improve the other headers a bit while just at it. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	9 months ago
Andreas Rheinhardt	40e6575aa3	all: Replace if (ARCH_FOO) checks by #if ARCH_FOO This is more spec-compliant because it does not rely on dead-code elimination by the compiler. Especially MSVC has problems with this, as can be seen in https://ffmpeg.org/pipermail/ffmpeg-devel/2022-May/296373.html or https://ffmpeg.org/pipermail/ffmpeg-devel/2022-May/297022.html This commit does not eliminate every instance where we rely on dead code elimination: It only tackles branching to the initialization of arch-specific dsp code, not e.g. all uses of CONFIG_ and HAVE_ checks. But maybe it is already enough to compile FFmpeg with MSVC with whole-programm-optimizations enabled (if one does not disable too many components).

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.

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

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	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
S.N. Hemanth Meenakshisundaram	5da19b53c6	Implement avcodec_get_channel_layout(). Patch by S.N. Hemanth Meenakshisundaram smeenaks:ucsd+edu. Originally committed as revision 24936 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 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
Carl Eugen Hoyos	5dfa637cca	Make function get_channel_name() static: It is only used in audioconvert.c. Originally committed as revision 22114 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
