Tim Walker	147715ca10	Add channel names to channel_names[] array for channels added in `b2890f5` Signed-off-by: Justin Ruggles <justin.ruggles@gmail.com>	13 years ago

Clément Bœsch	5fc51c3155	lavu: add 2.1 channel layout.	13 years ago
Mans Rullgard	019dd23657	Fix av_get_channel_layout_string() for positions >31 A value shifted left by >31 needs to have a 64-bit type. As there are no defined channels in this range, the fix is purely theoretical at this point, although it does avoid some invalid shifts triggering the overflow checker.

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
Nicolas George	e7062a1e9f	audioconvert: make av_get_channel_layout accept composite names. Signed-off-by: Nicolas George <nicolas.george@normalesup.org> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Nicolas George	ada8d485c0	audioconvert: prefer 5.X over 5.X(side). This is the logical consequence of commit ab539d9e: 5.X(back) is more common than 5.X(side). Signed-off-by: Nicolas George <nicolas.george@normalesup.org> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Nicolas George	1125571b73	audioconvert: use + in av_get_channel_layout_string. When constructing a channel layout string from individual channel names, + is a more practical separator than \|, because it is usually not a shell special character.

Marton Balint	d2ba604421	audioconvert: fix type of av_get_default_channel_layout Signed-off-by: Marton Balint <cus@passwd.hu> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Marton Balint	9bf4371e1b	audioconvert: make 7POINT1 channel layout the default for 8 channels Signed-off-by: Marton Balint <cus@passwd.hu> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Marton Balint	60aaf044f3	audioconvert: add av_get_default_channel_layout public function	13 years ago
Stefano Sabatini	6cfed11270	audioconvert: add explanatory comments to channel_names array Signed-off-by: Diego Biurrun <diego@biurrun.de>	13 years ago
Stefano Sabatini	3a0b5fa5e8	audioconvert: K&R whitespace cosmetics Signed-off-by: Diego Biurrun <diego@biurrun.de>	13 years ago
Carl Eugen Hoyos	ab539d9eb8	Use the shorter channel layout description for the common case.	13 years ago
Stefano Sabatini	e2affa8ce7	audioconvert: define unique strings for AV_CH_LAYOUT_5POINT{0,1}_BACK Previously the string for AV_CH_LAYOUT_5POINT{0,1}_BACK was the same of the string for AV_CH_LAYOUT_5POINT{0,1}. This is required for discerning the two channel layouts, given a channel layout string.	13 years ago
Diego Biurrun	dc25d79f49	Drop unnecessary directory prefixes from #include directives.	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	8b69c2f463	Make av_get_channel_layout_string() guess the number of channels if it was not provided. Originally committed as revision 26324 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
