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	392acaedcb	ALSA: fix use of period_size. period_size is in frames, while the demuxer assumed it was in bytes, resulting in short reads.	14 years ago

Reimar Döffinger	1109680434	Revert "build: Remove redundant config.mak includes from subdirectory Makefiles." This reverts commit `a6213f3dce`.	14 years ago
Diego Biurrun	a6213f3dce	build: Remove redundant config.mak includes from subdirectory Makefiles. Calling Make from subdirectories is not supported and config.mak has multiple inclusion guards anyway, so the top-level include is enough.	14 years ago

Stefano Sabatini	41b68dce4d	lavdev: improve feedback in case of invalid frame rate/size Show the invalid string in the error message. While at it also prefer "Could not" over "Couldn't", plain forms are preferred over contractions (simplify readability, especially for non English-savvy people).

Stefano Sabatini	a4bda40544	vfwcap: prefer "framerate_q" over "fps" in vfw_read_header() The variable is used for containing the parsed value of framerate, using a lexically consistent name eases readability/understanding. Signed-off-by: Anton Khirnov <anton@khirnov.net>	14 years ago
Stefano Sabatini	e60068baeb	v4l2: prefer "framerate_q" over "fps" in v4l2_set_parameters() The variable is used for containing the parsed value of framerate, using a lexically consistent name eases readability/understanding. Signed-off-by: Anton Khirnov <anton@khirnov.net>	14 years ago
Stefano Sabatini	a5351720cc	fbdev: prefer "framerate_q" over "fps" in device context The variable is used for containing the parsed value of framerate, using a lexically consistent name eases readability/understanding. Signed-off-by: Anton Khirnov <anton@khirnov.net>	14 years ago
Stefano Sabatini	da51a7c69c	bktr: prefer "framerate" over "fps" for grab_read_header() The variable is used for containing the parsed value of s1->framerate, using a lexically consistent name ease readability/understanding. Signed-off-by: Anton Khirnov <anton@khirnov.net>	14 years ago
Nicolas George	147bcf27c4	ALSA: implement channel layout for playback. Currently quad, 5.0, 5.1 and 7.1 are implemented.
