* audio_output: added method pause()Max Kellermann2008-09-291-0/+2
| | | | | | | | | | | | pause() puts the audio output into pause mode: if supported, it may perform a special action, which keeps the device open, but does not play anything. Output plugins like "shout" might want to play silence during pause, so their clients won't be disconnected. Plugins which do not support pausing will simply be closed, and have to be reopened when unpaused. This pach includes an implementation for the shout plugin, which sends silence chunks.
* audio: removed isAudioDeviceOpen()Max Kellermann2008-09-101-2/+0
| | | | The function isAudioDeviceOpen() is never used.
* audio: moved cmpAudioFormat() to audio_format.hMax Kellermann2008-09-091-2/+0
| | | | | Rename it to audio_format_equals() and return "true" if they are equal.
* audio: replaced copyAudioFormat() with simple assignmentMax Kellermann2008-09-091-2/+0
| | | | | | | | | The "!src" check in copyAudioFormat() used to hide bugs - one should never pass NULL to it. There is one caller which might pass NULL, add a check in this caller. Instead of doing mempcy(), we can simply assign the structures, which looks more natural.
* output: static audio_output_plugin list as arrayMax Kellermann2008-09-081-1/+0
| | | | | | Instead of having to register each output plugin, store them statically in an array. This eliminates the need for the List library here, and saves some small allocations during startup.
* audio_format: converted typedef AudioFormat to struct audio_formatMax Kellermann2008-09-071-8/+8
| | | | | Get rid of CamelCase, and don't use a typedef, so we can forward-declare it, and unclutter the include dependencies.
* audio: don't pass "fd" to printAudioDevices()Max Kellermann2008-09-071-1/+2
| | | | Pass the client struct instead.
* audio: don't pass "fd" to {en,dis}ableAudioDevice()Max Kellermann2008-09-071-2/+2
| | | | No protocol code in the audio output library.
* include cleanupMax Kellermann2008-09-061-1/+2
| | | | As usual, include only headers which are really needed.
* tag: renamed MpdTag and MpdTagItem to struct tag, struct mpd_tag_itemMax Kellermann2008-08-291-1/+1
| | | | | Getting rid of CamelCase; not having typedefs also allows us to forward-declare the structures.
* pass constant pointersMax Kellermann2008-08-291-1/+1
| | | | And again, convert arguments to const.
* moved struct AudioFormat to audio_format.hMax Kellermann2008-08-261-12/+1
| | | | | We want to expose the AudioFormat structure to plugins; remove some clutter by moving its declaration to a separate header file.
* remove audioDeviceStates from playerData and getPlayerDataEric Wong2008-06-021-2/+0

* clean up CPP includesMax Kellermann2008-04-121-2/+0
| | | | | | | | | Try to only include headers which are really needed. We should particularly check all "headers including other headers". The long-term goal is to have a manageable, small API for plugins (decoders, output) without so many mpd internals cluttering the namespace. git-svn-id: https://svn.musicpd.org/mpd/trunk@7319 09075e82-0dd4-0310-85a5-a0d7c8717e4f
* use size_t in audio.cMax Kellermann2008-04-121-1/+1
| | | | | | | Buffer sizes should be size_t. This is safe here, at least not unsafer than without the patch. I have no idea why audioBufferSize and audioBufferPos were explicitly declared as signed integer. git-svn-id: https://svn.musicpd.org/mpd/trunk@7296 09075e82-0dd4-0310-85a5-a0d7c8717e4f
* moved expression to audioFormatSizeToTime()Max Kellermann2008-04-121-0/+5
| | | | | | | The multi-line expression which calculates sizeToTime is hard to read, partly because "cb->audioFormat." is too long. Create a separate inline function in audio.h for that. git-svn-id: https://svn.musicpd.org/mpd/trunk@7277 09075e82-0dd4-0310-85a5-a0d7c8717e4f
* audio: use a machine word for array sizesMax Kellermann2008-03-261-3/+3
| | | | | | | | we do not save anything by limiting a variable to an unsigned char, since the compiler aligns it at machine word size anyway. however by using the full machine word, we save one instruction, and we remove the useless artificial limitation to 255. git-svn-id: https://svn.musicpd.org/mpd/trunk@7203 09075e82-0dd4-0310-85a5-a0d7c8717e4f
* Cleanup #includes of standard system headers and put them in one placeEric Wong2008-01-031-2/+1
| | | | | | | | | | | | | This will make refactoring features easier, especially now that pthreads support and larger refactorings are on the horizon. Hopefully, this will make porting to other platforms (even non-UNIX-like ones for masochists) easier, too. os_compat.h will house all the #includes for system headers considered to be the "core" of MPD. Headers for optional features will be left to individual source files. git-svn-id: https://svn.musicpd.org/mpd/trunk@7130 09075e82-0dd4-0310-85a5-a0d7c8717e4f

* audio: remove AUDIO_MAX_DEVICES limitEric Wong2006-08-011-2/+2

* interface/connection malloc reductions from mpd-keEric Wong2006-07-301-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch massively reduces the amount of heap allocations at the interface/command layer. Most commands with minimal output should not allocate memory from the heap at all. Things like repeatedly polling status, currentsong, and volume changes should be faster as a result, and more importantly, not a source of memory fragmentation. These changes should be safe in that there's no way for a remote-client to corrupt memory or otherwise do bad stuff to MPD, but an extra set of eyes to review would be good. Of course there's never any warranty :) No longer do we use FILE * structures in the interface, which means we don't have to allocate any new memory for most connections. Now, before you go on about losing the buffering that FILE * +implies+, remember that myfprintf() never took advantage of any of the stdio buffering features. To reduce the diff and make bugs easier to spot in the diff, I've kept myfprintf in places where we write to files (and not network interfaces). Expect myfprintf to go away entirely soon (we'll use fprintf for writing regular files). git-svn-id: https://svn.musicpd.org/mpd/trunk@4483 09075e82-0dd4-0310-85a5-a0d7c8717e4f

* rewrite statefile code for audio devicesEric Wong2006-03-181-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the words of the original author, it was 'crappy'. I tend to agree :) The code has also been broken for at least the past few months, and nobody bothered fixing it The previous format it was overly complex: 5 lines to describe each device. The new format is one-line per-device: audio_device_state:%d:%s %d - 0 for disabled, any integer for enabled %s - name of the device as specified in the config file, whitespace and all Incompatibilities: * Output names are now _required_ to be unique. This is required because the new format relies solely on the name of the audio device. Relying on the device IDs internal to MPD was a bad idea anyways since the user usually has none or very little idea how they're generated, and adding a new device or removing one from a config would throw things off completely. This is also just a Good Idea(TM) because it makes things less confusing to users when they see it in their clients. * Output states are not preserved from the previous format. Not a big deal, since the previous code was never officially released. Also, it's been broken for months now, so I doubt anybody would notice :) git-svn-id: https://svn.musicpd.org/mpd/trunk@3928 09075e82-0dd4-0310-85a5-a0d7c8717e4f
