2008-10-29output: use bool for return values and flagsMax Kellermann1-1/+1
Don't return 0/-1 on success/error, but true/false. Instead of int, use bool for storing flags.
2008-10-26output: don't compile plugins which are disabledMax Kellermann1-5/+0
Don't compile the sources of disabled output plugins at all.
2008-10-26renamed src/audioOutputs/ to src/output/Max Kellermann1-0/+0
Again, no CamelCase in the directory name.
2008-10-09shout: removed DISABLED_SHOUT_ENCODER_PLUGINMax Kellermann1-3/+0
Having an array with disabled entries sucks. Removed that DISABLED_SHOUT_ENCODER_PLUGIN macro, and fill the plugin list only with plugins which are actually enabled. This should be done for all plugin types.
2008-09-29audio_output: added method pause()Max Kellermann1-0/+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.
2008-09-12shout: make the shout_buffer staticMax Kellermann1-2/+1
Since the buffer size is known at compile time, we can save an indirection by declaring it as a char array instead of a pointer. That saves an extra allocation, and we can calculate with the compile-time constant sizeof(data) instead of the attribute "max_len".
2008-09-12shout: constant plugin declarationsMax Kellermann1-3/+3
Declare both shout plugins "const", since they will never change, once initialized at compile time.
2008-09-12shout: removed typedefs on structs and plugin methodsMax Kellermann1-34/+27
Don't typedef the structs at all. It is easier to forward-declare this way. Don't typedef methods. They are used exactly once, a few lines below.
2008-09-12shout: added mp3 encoderEric Wollesen1-0/+1
[mk: moved this patch after "Refactor and cleanup of shout Ogg and MP3 audio outputs". The original commit message follows, although it is outdated:] Creation of shout_mp3 audio output plugin. Basically I just copied the existing shout plugin and replaced ogg with lame. Uses lame for mp3 encoding. Next step is to pull common functionality out of each shout plugin and share it between them. Configuration options for "shout_mp3" are the same as for "shout".
2008-09-12shout: introduce pluggable encoder APIEric Wollesen1-29/+35
I've perhaps gone a bit overboard, but here's the current rundown: Both Ogg and MP3 use the "shout" audio output plugin. The shout audio output plugin itself has two new plugins, one for the Ogg encoder, and another for the MP3 (LAME) encoder. Configuration for an Ogg stream doesn't change. For an MP3 stream, configuration is the same as Ogg, with two exceptions. First, you must specify the optional "encoding" parameter, which should be set to "mp3". See mpd.conf(5) for more details. Second, the "quality" parameter is reversed for LAME, such that 1 is high quality for LAME, whereas 10 is high quality for Ogg. I've decomposed the code so that all libshout related operations are done in audioOutput_shout.c, all Ogg specific functions are in audioOutput_shout_ogg.c, and of course then all LAME specific functions are handled in audioOutput_shout_mp3.c. To develop encoder plugins for the shout audio output plugin, I basically just mimicked the plugin system used for audio outputs. This might be overkill, but hopefully if anyone ever wants to support some other sort of stream, like maybe AAC, FLAC, or WMA (hey it could happen), they will hopefully be all set. The Ogg encoder is slightly less optimal under this configuration. It used to send shout data directly out of its ogg_page structures. Now, in the interest of encapsulation, it copies the data from its ogg_page structures into a buffer provided by the shout audio output plugin (see audioOutput_shout_ogg.c, line 77.) I suspect the performance impact is negligible. As for metadata, I'm pretty sure they'll both work. I wrote up a test scaffold that would create a fake tag, and tell the plugin to send it out to the stream every few seconds. It seemed to work fine. Of course, if something does break, I'll be glad to fix it. Lastly, I've renamed lots of things into snake_case, in keeping with normalperson's wishes in that regard. [mk: moved the MP3 patch after this one. Splitted this patch into several parts; the others were already applied before this one. Fixed a bunch GCC warnings and wrong whitespace modifications. Made it compile with mpd-mk by adapting to its prototypes]
2008-09-12shout: send shout metadataEric Wollesen1-1/+3
Support sending metadata to a shout server using shout_metadata_new() and shout_metadata_add(). The Ogg Vorbis encoder does not support this currently. [mk: this patch was separated from Eric's patch "Refactor and cleanup of shout Ogg and MP3 audio outputs", I added a description]
2008-09-12shout: added struct _ogg_vorbis_dataMax Kellermann1-4/+8
Preparing the merge of Eric Wollesen's patch "Refactor and cleanup of shout Ogg and MP3 audio outputs": we declare one of the struct types here, to make the merge smoother.
2008-09-12shout: added shout_bufferEric Wollesen1-4/+10
The Ogg encoder is slightly less optimal under this configuration. It used to send shout data directly out of its ogg_page structures. Now, in the interest of encapsulation, it copies the data from its ogg_page structures into a buffer provided by the shout audio output plugin (see audioOutput_shout_ogg.c, line 77.) I suspect the performance impact is negligible. [mk: this patch and its description was separated from Eric's patch "Refactor and cleanup of shout Ogg and MP3 audio outputs"]
2008-09-12shout: moved code to audioOutput_shout_ogg.cMax Kellermann1-0/+15
Begin dividing audioOutput_shout.c: move everything OGG Vorbis related to audioOutput_shout_ogg.c. The header audioOutput_shout.h has to keep its dependency on vorbis/vorbisenc.h, because it needs the vorbis encoder types. For this patch, we have to export several internal functions with generic names to the ABI; these will be removed later when the encoder plugin patches are merged.
2008-09-12shout: moved declarations to audioOutput_shout.hMax Kellermann1-22/+42
Prepare the split of the shout plugin into multiple sources: move all important declarations to audioOutput_shout.h.
2008-04-12clean up CPP includesMax Kellermann1-1/+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

2008-01-03Cleanup #includes of standard system headers and put them in one placeEric Wong1-10/+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
