* ao_coreaudio: move channel mapping away from utilsStefano Pigozzi2014-07-021-123/+0
| | | | | Channel mapping functions are only used in the AUHAL based coreaudio, so move them there.
* ao_coreaudio: fill asbd with an helper functionStefano Pigozzi2014-07-021-0/+26

* ao_coreaudio: move device related functions to the new AOStefano Pigozzi2014-07-021-249/+0

* ao_coreaudio: move spdif code to a new AOStefano Pigozzi2014-07-021-0/+62
| | | | | | | | | | | | | | | | The mplayer1/2/mpv CoreAudio audio output historically contained both usage of AUHAL APIs (these go through the CoreAudio audio server) and the Device based APIs (used only for output of compressed formats in exclusive mode). The latter is a very unwieldy and low level API and pretty much forces us to write a lot of code for little workr. Also with the widespread of HDMI, the actual need for outputting compressed audio directly to the device is getting lower (it was very useful with S/PDIF for bandwidth constraints not allowing a number if channels transmitted in LPCM). Considering how invasive it is (uses hog/exclusive mode), the new AO (`ao_coreaudio_device`) is not going to be autoprobed but the user will have to select it.
* Audit and replace all ctype.h useswm42014-07-011-2/+2
| | | | | | | | | | | | | | | | Something like "char *s = ...; isdigit(s[0]);" triggers undefined behavior, because char can be signed, and thus s[0] can be a negative value. The is*() functions require unsigned char _or_ EOF. EOF is a special value outside of unsigned char range, thus the argument to the is*() functions can't be a char. This undefined behavior can actually trigger crashes if the implementation of these functions e.g. uses lookup tables, which are then indexed with out-of-range values. Replace all <ctype.h> uses with our own custom mp_is*() functions added with misc/ctype.h. As a bonus, these functions are locale-independent. (Although currently, we _require_ C locale for other reasons.)
* ao_coreaudio: skip unknown channel labelsStefano Pigozzi2014-05-101-0/+2
| | | | | | | | | | | | | I don't think this is really a very good idea because it is conceptually incorrect but other prominent multimedia programs use this approach (VLC and xbmc), and it seems to make the conversion more robust in certain cases. For example it has been reported, that configuring a receiver that can output 7.1 to output 5.1, will make CoreAudio report 8 channel descriptions, and the last 2 descriptions will be tagged kAudioChannelLabel_Unknown. Fixes #737
* ao_coreaudio: cosmetic change of loop ending conditionStefano Pigozzi2014-05-101-1/+1

* ao_coreaudio: use description-based channel layoutsStefano Pigozzi2014-05-101-74/+47
| | | | | | | | | | | | CoreAudio supports 3 kinds of layouts: bitmap based, tag based, and speaker description based (using either channel labels or positional data). Previously we tried to convert everything to bitmap based channel layouts, but it turns out description based ones are the most generic and there are built-in CoreAudio APIs to perform the conversion in this direction. Moreover description based layouts support waveext extensions (like SDL and SDR), and are easier to map to mp_chmaps.
* ao_coreaudio: pass layout by reference to logging functionStefano Pigozzi2014-05-101-7/+7
| | | | | Apparently passing the struct by value somehow messed with the value of some fields.
* ao_coreaudio: log even more info in verbose modeStefano Pigozzi2014-04-241-5/+27
| | | | | This logs more info that can be used for debugging purposes, in particular it prints all the AudioChannelDescription in the descriptions array.
* ao_coreaudio: add verbose output of detected channel layoutsStefano Pigozzi2014-04-231-0/+5
| | | | This can be useful for debugging purposes.
* msg: rename mp_msg_log -> mp_msgwm42013-12-211-1/+1
| | | | Same for companion functions.
* ao_coreaudio: simplify ch label to speaker id conversionStefano Pigozzi2013-11-271-23/+37
| | | | | | | | Previous code was using the values of the AudioChannelLabel enum directly to create the channel bitmap. While this was quite smart it was pretty unreadable and fragile (what if Apple changes the values of those enums?). Change it to use a 'dumb' conversion table.
* ao_coreaudio: map channel labels needed for 8ch layoutsStefano Pigozzi2013-11-271-4/+30
| | | | | | The code stopped at kAudioChannelLabel_TopBackRight and missed mapping for 5 more channel labels. These are in a completely different order that the mpv ones so they must be mapped manually.
* ao_coreaudio: move to new log APIStefano Pigozzi2013-08-011-54/+53

* ao_coreaudio: remove useless definesStefano Pigozzi2013-08-011-3/+0
| | | | They are already defined in the header file
* ao_coreaudio: switch properties getters to tallocStefano Pigozzi2013-07-221-4/+4

* ao_coreaudio: reduce verbosity of the chmapping codeStefano Pigozzi2013-07-221-2/+2
|
* ao_coreaudio: refactor chmap detectionStefano Pigozzi2013-07-221-0/+81
| | | | | | b2f9e0610 introduced this functionality with code that was quite 'monolithic'. Split the functionality over several functions and ose the new macros to get array properties.
* ao_coreaudio: refactor properties codeStefano Pigozzi2013-07-221-30/+19
| | | | | | | | Introduce some macros to deal with properties. These allow to work around the limitation of CoreAudio's API being `void **` based. The macros allow to keep their client's code DRY, by not asking size and other details which can be derived by the macro itself. I have no idea why Apple didn't design their API like this in the first place.
* ao_coreaudio: move utils functions to snake_caseStefano Pigozzi2013-07-221-28/+23

* ao_coreaudio: split ao_coreaudio_common in two filesStefano Pigozzi2013-07-221-0/+358
* ao_coreaudio_utils: contains several utility function * ao_coreaudio_properties: contains functions to set and get audio object properties. Conflicts: audio/out/ao_coreaudio.c
