Nicolas George	55910e1894	lavd/alsa: simplify reordering functions definition.	12 years ago
Justin Ruggles	a903f8f087	Include libavutil/channel_layout.h instead of libavutil/audioconvert.h Also reorder some other #include when applicable.	12 years ago
Anton Khirnov	36ef5369ee	Replace all CODEC_ID_* with AV_CODEC_ID_*	13 years ago
Mans Rullgard	cc276c85d1	Make channel layout masks unsigned It makes more sense for a bit mask to use an unsigned type. The change should be source and binary compatible on all supported systems, hence micro version bump. Fixes a few invalid shifts. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Anton Khirnov	4d77d57d20	alsa: add missing header Fixes compile with next lavc major.	13 years ago
Carl Eugen Hoyos	4bc447a3c5	Fix compilation with --disable-everything --enable-outdev=alsa. Bug found and analysed by skierpage.	13 years ago
Justin Ruggles	e35c674d13	alsa: limit buffer_size to 32768 frames. In testing, the file output plugin gave a max buffer size of about 20 million frames, which is way more than what is really needed and causes a memory allocation error on my system.	14 years ago
Justin Ruggles	8bfd7f6a47	alsa: fallback to buffer_size/4 for period_size. buffer_size/4 is the value used by aplay. This fixes output to null devices, e.g. writing ALSA output to a file.	14 years ago
Nicolas George	5d35b279e2	ALSA demuxer: use av_gettime and a timefilter. The PTS for captured audio was measured using snd_pcm_htimestamp. snd_pcm_htimestamp hangs when the input is a dsnoop plugin. Furthermore, at some point, snd_pcm_htimestamp started returning monotonic timestamps rather than wall clock timestamps, in most but not all situations. Monotonic timestamps are fine, but ffmpeg uses wall clock timestamps everywhere else, and we have no API to inform the user which kind of timestamps it is. A separate snd_pcm_htimestamp is only slightly less accurate than snd_pcm_htimestamp: the standard deviation for the difference between two consecutive timestamps is (on my hardware): - ~13 µs with snd_pcm_htimestamp; - ~35 µs with av_gettime; - ~5 µs with av_gettime and a timefilter.	14 years ago
Anton Khirnov	ffc6c8a430	Support u8, s8, alaw and mulaw channel reordering in alsa.	14 years ago
Nicolas George	147bcf27c4	ALSA: implement channel layout for playback. Currently quad, 5.0, 5.1 and 7.1 are implemented. Implementing support for other formats/layouts and capture should be straightforward. 5.0 and 7.1 support by Carl Eugen Hoyos. Signed-off-by: Anton Khirnov <anton@khirnov.net>	14 years ago
Carl Eugen Hoyos	2359aeb52d	alsa: support unsigned variants of already supported signed formats.	14 years ago
Carl Eugen Hoyos	921715edff	alsa: add support for more formats. Specifically, f32, f64, s32, s24, a-law and mu-law. Signed-off-by: Anton Khirnov <anton@khirnov.net>	14 years ago
Stefano Sabatini	6b899e16de	lavdev: prefer the inclusion of avdevice.h over that of libavformat/avformat.h	14 years ago
Carl Eugen Hoyos	f4bc923ec1	Allow to print wider unsupported channel layouts.	14 years ago
Carl Eugen Hoyos	b8a4444266	AV_CH_LAYOUT_2_2 does not need channel reordering for alsa output.	14 years ago
Carl Eugen Hoyos	19de9d5646	Cosmetics: Fix indentation and move one line.	14 years ago
Carl Eugen Hoyos	460acdf059	Support alsa channel reordering for float.	14 years ago
Carl Eugen Hoyos	e2049edb4e	Add forgotten line to silence a warning for int32. AV_CH_LAYOUT_QUAD is the only (multi-) channel layout that has the same channel ordering for FFmpeg and alsa.	14 years ago
Carl Eugen Hoyos	47c0c8ca9d	Also support alsa channel reordering for u16 and u32 formats.	14 years ago
Carl Eugen Hoyos	1171d45f6c	Rename the s16 and s32 alsa reorder functions as int16 and int32. The functions will also be used for unsigned formats.	14 years ago
Carl Eugen Hoyos	0ae2a0366f	Support unsigned variants of already supported signed formats in alsa.	14 years ago
Carl Eugen Hoyos	075a55603f	Support a-law and mu-law output in alsa.	14 years ago
Carl Eugen Hoyos	ff2614ee4c	Fix output of AV_CH_LAYOUT_5POINT0 via alsa by reordering channels.	14 years ago
Carl Eugen Hoyos	71306c5d21	Support CODEC_ID_PCM_F64* output via alsa (stereo only).	14 years ago
Carl Eugen Hoyos	5778466e92	Support CODEC_ID_PCM_S24* output via alsa (stereo only).	14 years ago
Carl Eugen Hoyos	2ed05f657f	Add support for pcm_f32* to alsa.	14 years ago
Carl Eugen Hoyos	4d1d6f7a3c	Support s32 output via alsa audio device.	14 years ago
Carl Eugen Hoyos	efec2d7b35	Template alsa reordering functions.	14 years ago
Nicolas George	1e96d4c71e	ALSA: fix a stupid bad use of av_freep. It caused a segfault when channel reordering was in use and the last chunk of data was not silent. Spotted and diagnosed by Carl Eugen Hoyos.	14 years ago
Carl Eugen Hoyos	3efaa24f85	Also use alsa_reorder_s16_out_51() for AV_CH_LAYOUT_5POINT1.	14 years ago
Nicolas George	813dbb4442	ALSA: implement channel layout for playback. Currently, only S16 quad, 5.1 and 7.1 are implemented. Implementing support for other formats/layouts and capture should be straightforward. 7.1 support by Carl Eugen Hoyos.	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 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
Stefano Sabatini	5ae092ee34	Replace all the occurrences of AVERROR_EIO with AVERROR(EIO), and mark AVERROR_EIO for deletion at the next major bump. Originally committed as revision 22513 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Matthieu Castet	419bddd366	Include alsa headers before the internal FFmpeg headers. This avoids symbol redefinitions problems, for example avoids the "free" symbol to be redefined before system headers actually using it are included, thus breaking compilation. In particular this change allows to build FFmpeg with salsa. Patch by matthieu castet <$surname.mat?hieu@free fr>. Originally committed as revision 20665 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Carl Eugen Hoyos	899f38df62	Fix two icc warnings #188 : enumerated type mixed with another type. Originally committed as revision 18515 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Luca Abeni	3cac2f1301	Fix AVFMT_FLAG_NONBLOCK in alsa Originally committed as revision 17863 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
Nicolas George	35fd81224a	Add ALSA support in libavdevice. Patch by Nicolas George: name surname normalesup org Original thread: [FFmpeg-devel] [PATCH] ALSA for libavdevice Date: 12/09/2008 07:17 PM Originally committed as revision 16800 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
