* output: include cleanupMax Kellermann2009-02-161-0/+1
| | | | | Don't include output_api.h in output_internal.h. This change requires adding missing includes in several sources.
* mixer_api: replaced method "control()" with "{get,set}_volume()"Max Kellermann2009-02-161-6/+14
| | | | | The method control() is too complicated, and overengineered. Replace it with two trivial functions: get_volume() and set_volume().
* output_plugin: replaced method "control()" with "mixer()"Max Kellermann2009-02-161-6/+10
| | | | | The output plugin shouldn't know any specifics of the mixer API. Make it return the mixer object, and let the caller deal with it.
* audio: moved code to output_command.cMax Kellermann2009-02-111-35/+0
| | | | | | The output_command library provides a command interface to the audio outputs. It assumes the input comes from an untrusted source (i.e. the client) and verifies all parameters.
* audio: replaced parseAudioConfig() with audio_format_parse()Max Kellermann2009-02-111-57/+8
| | | | | | Added audio_format_parse() in a separate library, with a modern interface: return a GError instead of logging errors. This allows the caller to deal with the error.
* audio: moved code to output_all.cMax Kellermann2009-02-101-255/+20
| | | | | Moved code which deals with all audio outputs at once into a separate library.
* audio: moved protocol code to output_print.cMax Kellermann2009-02-101-16/+0
|
* audio: moved state file code to output_state.cMax Kellermann2009-02-101-53/+0
|
* audio: removed isCurrentAudioFormat()Max Kellermann2009-02-101-8/+0
| | | | This function isn't used anymore.
* audio: added output enumeration functionsMax Kellermann2009-02-101-0/+22
| | | | Added audio_output_get(), audio_output_find().
* audio: added audio_output_config_count()Max Kellermann2009-02-101-1/+7
| | | | | | audio_output_config_count() returns the number of audio outputs in the configuration file. It is only used by initAudioDriver(). The public function audio_output_count() now returns audioOutputArraySize.
* use g_free() instead of free()Max Kellermann2009-01-251-1/+1
| | | | | | On some platforms, g_free() must be used for memory allocated by GLib. This patch intends to correct a lot of occurrences, but is probably not complete.
* mixer: removed mixer_configure_legacy(), AC_MIXER_CONFIGUREMax Kellermann2009-01-251-17/+0
| | | | Those have been superseded by the new legacy configuration code.
* conf: const pointers in block get functionsMax Kellermann2009-01-251-3/+3
| | | | | All config_get_block_*() functions should accept constant config_param pointers.
* conf: no CamelCase, part IMax Kellermann2009-01-171-6/+6
| | | | Renamed functions, types, variables.
* renaming mixer.h to mixer_api.hViliam Mateicka2009-01-041-1/+1
|
* audio: use GLib instead of utils.hMax Kellermann2009-01-031-2/+2
|
* Moving mixers to audio outputsViliam Mateicka2008-12-311-0/+55
|
* exporting functionsViliam Mateicka2008-12-311-1/+1
|
* removed os_compat.hMax Kellermann2008-12-291-1/+2
| | | | | Only include headers which are really needed. os_compat.h aimed to make MPD easily portable, but was never actually made portable.
* utils: removed myFgets()Max Kellermann2008-12-281-1/+3
| | | | Replaced myFgets() with fgets() + g_strchomp().
* output_control: no static "notify" initializationMax Kellermann2008-12-271-0/+4
| | | | Don't use NOTIFY_INITIALIZER to initialize audio_output_client_notify.
* output: use GLib instead of log.h/util.hMax Kellermann2008-11-251-19/+18
|
* output: don't allow length==0Max Kellermann2008-11-021-0/+1
| | | | | Nobody should call playAudio() with an empty chunk. Add some assertions on that.
* output: removed audio_output.resultMax Kellermann2008-10-291-5/+3
| | | | | Since open() and play() close the device on error, we can simply check audio_output.open instead of audio_output.result after a call.
* output: delay reopen after device failureMax Kellermann2008-10-291-0/+1
| | | | | | | When one of several output devices failed, MPD tried to reopen it quite often, wasting a lot of resources. This patch adds a delay: wait 10 seconds before retrying. This might be changed to exponential delays later, but for now, it makes the problem go away.
* output: moved code to audio_output_update()Max Kellermann2008-10-291-8/+2
| | | | Moved code from syncAudioDeviceStates() to audio_output_update().
* output: always call cancel() before stop()Max Kellermann2008-10-291-10/+1
| | | | | | Stopping an audio output device without cancelling its buffer doesn't make sense. Combine the two operations, which saves several cancel calls.
* output: moved audioDeviceStates to audio_output.enabledMax Kellermann2008-10-291-20/+6
|
* output: use bool for return values and flagsMax Kellermann2008-10-291-14/+14
| | | | | Don't return 0/-1 on success/error, but true/false. Instead of int, use bool for storing flags.
* audio: call closeAudioDevice() on errorMax Kellermann2008-10-291-5/+2
| | | | | Instead of implementing another loop which calls audio_output_close() on all configured devices, simply call closeAudioDevice().
* audio: removed variable "audioOpened"Max Kellermann2008-10-291-9/+1
| | | | This variable is never read, and can be removed.
* utils: use g_str_has_prefix() instead of prefixcmp()Max Kellermann2008-10-281-1/+3
| | | | Remove duplicated code from MPD.
* audio: allow 24 and 8 bit outputMax Kellermann2008-10-231-4/+2
| | | | | | | I added 24 bit support a while ago, but it wasn't possible to force 24 bit output. Add 24 and 8 bit to the list of allowed sample sizes. Although 8 bit audio isn't as widely used as 24 bit, there is no reason to exclude it.
* output_buffer: don't split framesMax Kellermann2008-10-231-0/+3
| | | | | | | Splitting a frame between two buffer chunks causes distortion in the output. MPD used to assume that the chunk size 1020 would never cause splitted frames, but that isn't the case for 24 bit stereo (127.5 frames), and even less for files with even more channels.
* command: added command "idle"Max Kellermann2008-10-141-0/+3
| | | | | | "idle" waits until something noteworthy happens on the server, e.g. song change, playlist modified, database updated. This allows clients to keep up to date without polling.
* audio: don't clear input_audio_format on openAudioDevice(NULL)Max Kellermann2008-10-131-3/+1
| | | | | | | Commit 80a2c937 broke resume after pause: it cleared the input_audio_format when it attempted to simplify a complicated expression. Don't clear it, just assign input_audio_format if a new format was specified.
* audio: renamed the audio_format variablesMax Kellermann2008-10-121-17/+13
| | | | | | Renamed audio_configFormat to configured_audio_format. Renamed audio_buffer.format to input_audio_format. Simplified its initialization in openAudioDevice().
* audio: removed enum ad_stateMax Kellermann2008-10-121-22/+14
| | | | | All what's left from ad_state is a simple boolean flag (ENABLE / DISABLE). Convert it to a C99 bool.
* audio: removed audio_buffer.bufferMax Kellermann2008-10-121-69/+2
| | | | | | audio.c maintained one of MPD's many layers of audio buffers. It was without any benefit, since playAudio() can simply send the source buffer directly to the audio output plugin.
* audio_format: added audio_format_frame_size()Max Kellermann2008-10-101-1/+1
| | | | | | | A frame contains one sample per channel, thus it is sample_size * channels. This patch includes some cleanup for various locations where the sample size for 24 bit audio was still 3 bytes (instead of 4).
* audio_format: renamed sampleRate to sample_rateMax Kellermann2008-10-101-5/+5
| | | | | The last bit of CamelCase in audio_format.h. Additionally, rename a bunch of local variables.
* audio_format: unsigned integersMax Kellermann2008-10-101-4/+4
| | | | "bits" and "channels" cannot be negative.
* use the "bool" data type instead of "int"Max Kellermann2008-10-081-1/+2
| | | | "bool" should be used in C99 programs for boolean values.
* audio_output: added method pause()Max Kellermann2008-09-291-0/+13
| | | | | | | | | | | | 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.
* Switch to C99 types (retaining compat with old compilers)Eric Wong2008-09-291-3/+3
| | | | | | | | | | | | | | | Seeing the "mpd_" prefix _everywhere_ is mind-numbing as the mind needs to retrain itself to skip over the first 4 tokens of a type to get to its meaning. So avoid having extra characters on my terminal to make it easier to follow code at 2:30 am in the morning. Please report any new issues you may come across on Free toolchains. I realize how difficult it can be to build/maintain cross-compiling toolchains and I have no intention of forcing people to upgrade their toolchains to build mpd. Tested with gcc 2.95.4 and and gcc 4.3.1 on x86-32.
* output: fix the "outputenabled" valueMax Kellermann2008-09-281-1/+1
| | | | | Patch 9a5b5998 broke the "outputenabled" value of the "outputs" response. Make it print "1" if the output is enabled, "0" otherwise.
* audio_output: workaround for deadlockMax Kellermann2008-09-261-2/+4
| | | | | | | | During debugging, I found a deadlock between flushAudioBuffer() and the audio_output_task(): audio_output_task() didn't notice that there is a command, and flushAudioBuffer() waited forever in notify_wait(). I am not sure yet what is the real cause; work around this for now by waking up non-finished audio outputs in every iteration.
* output: removed DEVICE_ON, DEVICE_OFFMax Kellermann2008-09-241-29/+14
| | | | | | | To check whether a device is really on or off, we should rather check audio_output.open, instead of managing another variable. Wrap audio_output.open in the inline function audio_output_is_open() and use it instead of DEVICE_ON and DEVICE_OFF.
* output: semi-asynchronous playbackMax Kellermann2008-09-241-13/+63
| | | | | | | Send an output buffer to all output plugins at the same time, instead of waiting for each of them separately. Make several functions non-blocking, and introduce the new function audio_output_wait_all() to synchronize with all audio output threads.
