Ganesh Ajjanagadde	38f4e973ef	all: fix -Wextra-semi reported on clang This fixes extra semicolons that clang 3.7 on GNU/Linux warns about. These were trigggered when built under -Wpedantic, which essentially checks for strict ISO compliance in numerous ways.

Justin Ruggles	a903f8f087	Include libavutil/channel_layout.h instead of libavutil/audioconvert.h Also reorder some other #include when applicable.	12 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

Nicolas George	147bcf27c4	ALSA: implement channel layout for playback. Currently quad, 5.0, 5.1 and 7.1 are implemented.

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.

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>.
