* jack: removed sample_rate callbackMax Kellermann2009-01-301-20/+7
| | | | | | | | | | | Currently, the JACK plugin manipulates the audio_format struct which was passed to the open() method. This is very likely to break, because the plugin must not permanently store this pointer. After this patch, MPD ignores sample rate changes. It looks like other software is doing the same, and I guess this is a non-issue. This patch converts the audio_format pointer within jack_data into a static audio_format struct.
* configure.ac: detect jack_set_info_function()Max Kellermann2009-01-301-0/+5
| | | | | jack_set_info_function() is not provided by older libjack versions. Attempt to detect if it is available.
* jack: print info messagesMax Kellermann2009-01-301-0/+7
| | | | | Use jack_set_info_function() to install an info callback. Don't let libjack print them to stderr.
* jack: don't manually close on shutdownMax Kellermann2009-01-291-3/+1
| | | | Return false from mpd_jack_play(), let the MPD core close the device.
* jack: initialize output_ports if not configuredMax Kellermann2009-01-291-0/+3
| | | | Don't leave uninitialized bytes in the jack_data struct.
* jack: close JACK client on stopMax Kellermann2009-01-291-4/+4
| | | | When MPD stops playback, close the JACK client connection.
* jack: removed "bps" attributeMax Kellermann2009-01-291-5/+1
| | | | The "bps" attribute is calculated, but never used.
* jack: make mpd_jack_connect() return boolMax Kellermann2009-01-291-10/+10
| | | | Return true/false instead of 1/-1.
* jack: use loops for allocating/freeing ports/buffersMax Kellermann2009-01-291-36/+32
| | | | | | | Preparation for supporting other channel numbers than stereo: use loops instead of duplicating code for the second channel. Most likely, gcc will unroll these loops, so the binary won't be any different.
* jack: fail if jack_get_ports() returns NULLMax Kellermann2009-01-291-19/+23
| | | | | When jack_get_ports() returns NULL, we cannot have any ports to connect to, and the device cannot play anything.
* jack: use jack_port_name() instead of g_malloc()+sprintf()Max Kellermann2009-01-291-12/+2
| | | | | libjack's jack_port_name() function returns the effective port name, we don't need to do it manually.
* jack: initialize libjack's error function in mpd_jack_init()Max Kellermann2009-01-291-1/+2
| | | | | Do the global libjack initialization in the global plugin initialization function.
* jack: reduced sleep time to 1msMax Kellermann2009-01-291-1/+1
| | | | | | | | | | When waiting for free space in the ring buffer, the JACK plugin sleeped 10ms until there is enough space. This delay was too large for low-latency setups (<10ms), and created a lot of xruns. Work around that by reducing the sleep time to 1ms. A proper solution for this would be to use an event based approach, and we will do it, just not now.
* jack: clear "shutdown" flag on reconnectMax Kellermann2009-01-291-0/+2
| | | | | | | When the connection failed once, you had to restart MPD, because it never cleared the jack_data.shutdown flag. Instead, it refused to play anything "because there is no client thread" (which is wrong at that point).
* jack: allocate ring buffers before connectingMax Kellermann2009-01-291-5/+3
| | | | | If the ring buffers are allocated after jack_activate(), mpd_jack_process() might segfault because it attempts to access them.
* jack: register ports before activating clientsMax Kellermann2009-01-291-5/+5
| | | | Call jack_port_register() before jack_activate().
* use g_free() instead of free()Max Kellermann2009-01-257-12/+11
| | | | | | 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(), configure mixer in mixer_new()Max Kellermann2009-01-252-11/+3
| | | | | | | Allocate the mixer object when it is configured. Merged mixer_configure() into mixer_new(). mixer_new() was quite useless anyway.
* mixer: return a mixer struct pointerMax Kellermann2009-01-252-15/+17
| | | | Don't use statically allocated mixer objects.
* conf: allow param==NULLMax Kellermann2009-01-253-27/+10
| | | | | | | | Return the default value in the conf_get_block_*() functions when param==NULL was passed. This simplifies a lot of code, because all initialization can be done in one code path, regardless whether configuration is present.
* conf: const pointers in block get functionsMax Kellermann2009-01-2510-12/+12
| | | | | All config_get_block_*() functions should accept constant config_param pointers.
* alsa: added commentsMax Kellermann2009-01-251-3/+21
| | | | Document alsa_data members.
* alsa: frame_size is size_t, not intMax Kellermann2009-01-251-1/+1
| | | | frame_size is a memory size and should be a size_t, not a signed integer.
* alsa: no CamelCaseMax Kellermann2009-01-251-93/+103
| | | | Renamed types, functions, variables.
* alsa: fix option parsing and restore default period_timeDan McGee2009-01-251-3/+6
| | | | | | | | | | | | | | | | | | | Two bugs here led to a large number of interrupts being generated on the sound card when ALSA output is being used. Because we specify no default period_time, the sound card gives us 3000 interrupts/sec rather than a more sane 20 or 30. This completes the revert of dd7711 already started by 4ca24f. The larger bug was in the change to config_get_block_unsigned() and using 0 as the default value for both 'buffer_time' and 'period_time'. This means any pre-setting of these options in newAlsaData() gets wiped out. Add a new default for period_time, and ensure default values for buffer_time and period_time are used if none are provided by the user. Signed-off-by: Dan McGee <dan@archlinux.org> [mk: set defaults in newAlsaData() to fix auto-configuration; renamed "_MS" back to "_US" because ALSA expects microseconds, not milliseconds] Signed-off-by: Max Kellermann <max@duempel.org>
* null: added option to disable timer synchronizationMax Kellermann2009-01-221-1/+11
| | | | | | | The null plugin synchronizes the playback so it will happen in real time. This patch adds a configuration option which disables this: the playback will then be as fast as possible. This can be useful to profile MPD.
* null: implemented finish() methodMax Kellermann2009-01-221-0/+13
| | | | Free memory in the finish() method to make valgrind happy.
* null: no CamelCaseMax Kellermann2009-01-221-13/+18
| | | | Renamed functions and variables.
* conf: added config_get_block_unsigned()Max Kellermann2009-01-184-39/+7
| | | | Eliminate some more getBlockParam() invocations.
* conf: added config_get_block_string()Max Kellermann2009-01-187-86/+57
| | | | This replaces lots of getBlockParam() invocations.
* jack: parse "ports" setting with g_strsplit()Max Kellermann2009-01-181-20/+7
| | | | Don't modify the configured string.
* jack: use audio_output_get_name()Max Kellermann2009-01-181-11/+1
| | | | | Determine the audio output name with audio_output_get_name() instead of obtaining the name from the configuration again.
* conf: replaced getBoolBlockParam() with config_get_block_bool()Max Kellermann2009-01-172-9/+6
| | | | No "force" parameter, pass a default value instead.
* conf: no CamelCase, part IMax Kellermann2009-01-1710-26/+29
| | | | Renamed functions, types, variables.
* oss: evaluate the oss_open() return value properlyMax Kellermann2009-01-161-1/+1
| | | | It returns bool, not int.
* shout: enlarge buffer size to 32 kBAntoine Beaupré2009-01-141-1/+1
| | | | | | | I was having problems with shoutcast stream outputs before applying the attached patch, which enlarges the shoutcast output buffer. Ideally, this should be configurable, but this resolves the issue for my needs.
* Introducing mixer apiViliam Mateicka2009-01-102-15/+16
| | | | | This patch tryes to introduce pluggable mixer (struct mixer_plugin) along with some basic infrastructure (mixer_* functions). Instance of mixer (struct mixer) is used in alsa and oss output plugin
* added missing explicit config.h includesMax Kellermann2009-01-081-0/+1
|
* pcm_utils: moved conversion code to pcm_convert.cMax Kellermann2009-01-071-1/+1
| | | | | All what's left in pcm_utils.h is the pcm_range() utility function, which is only used internally by pcm_volume and pcm_mix.
* fix G_BYTE_ORDER checkMax Kellermann2009-01-053-3/+3
| | | | "#ifdef G_BYTE_ORDER == G_BIG_ENDIAN" cannot work, of course.
* use GLib byte order macrosMax Kellermann2009-01-053-9/+10
|
* renaming mixer.h to mixer_api.hViliam Mateicka2009-01-042-2/+2

* null, fifo: use GLib instead of utils.hMax Kellermann2009-01-032-7/+8
|
* ao: use g_strsplit() instead of strtok_r()Max Kellermann2009-01-031-37/+15
| | | | g_strsplit() is more portable than strtok_r().
* alsa: use GLib instead of utils.hMax Kellermann2009-01-021-3/+2
|
* jack: use GLib instead of utils.hMax Kellermann2009-01-021-15/+14
|
* jack: duplicate jack_get_ports() return valuesMax Kellermann2009-01-021-3/+4
| | | | | | | | | JACK documentation states: "The caller is responsible for calling free(3) any non-NULL returned value." This does not seem to include the array elements. Duplicate them after jack_get_ports(), and free only the array. Convert JackData.output_ports to non-const.
* output plugins: don't include gcc.hMax Kellermann2009-01-019-24/+29
| | | | Use GLib's G_GNUC_UNUSED instead of gcc.h's mpd_unused.
* null: don't include gcc.hMax Kellermann2009-01-011-4/+7
| | | | Use GLib's G_GNUC_UNUSED instead of macros from gcc.h.
