2008-11-03decoder: no CamelCaseMax Kellermann1-4/+4
Renamed variables and functions.
2008-11-03decoder_api: send song tag in decoder_data()Max Kellermann1-8/+26
Before passing the first chunk to the audio output device, send the current song's tag.
2008-11-03decoder_api: automatically send stream tagMax Kellermann1-0/+51
If an input stream provides tags (e.g. from an icecast server), send them in the decoder_data() and decoder_tag() methods. Removed the according code from the mp3 and oggvorbis plugins - decoders shouldn't have to care about stream tags. This patch also adds the missing decoder_tag() invocation to the mp3 plugin.
2008-11-03decoder_api: no CamelCaseMax Kellermann1-34/+32
Renamed variables.
2008-11-02decoder_api: added decoder_tag()Max Kellermann1-0/+13
Provide an API for submitting additional tags from the stream.
2008-11-02decoder_api: pass "seekable" flag to decoder_initialized()Max Kellermann1-16/+8
Don't pass the "seekable" flag with every decoder_data() invocation. Since that flag won't change within the file, it is enough to pass it to decoder_initialized() once per file.
2008-11-02decoder: replaced music_pipe.audioFormat with dc.out_audio_formatMax Kellermann1-10/+13
.. and rename dc.audioFormat to dc.in_audio_format. The music pipe does not need to know the audio format, and its former "audioFormat" property indicated the format of the most recently added chunk, which might be confusing when you are reading the oldest chunks.
2008-11-02music_pipe: renamed ob_* functions to music_pipe_*Max Kellermann1-2/+2
Rename all functions to the new prefix.
2008-11-02renamed outputBuffer.[ch] to pipe.[ch]Max Kellermann1-1/+1
No CamelCase in the file name. The output_buffer struct is going to be renamed to music_pipe. There are so many buffer levels in MPD, and calling this one "output buffer" is wrong, because it's not the last buffer before the music reaches the output devices.
2008-11-01decoder: manage decoder list in a static arrayMax Kellermann1-11/+0
Currently, there is no way to dynamically load decoder plugins, thus we don't need a dynamic list to manage them.
2008-10-30decoder: use bool for return values and flagsMax Kellermann1-2/+2
Don't return 0/-1 on success/error, but true/false. Instead of int, use bool for storing flags.
2008-10-29decoder: automatically flush the output buffer after decoder exitsMax Kellermann1-5/+0
A decoder_flush() invocation was missing in the FLAC plugin, resulting in casual assertion failures due to a wrong assumption about the last chunk's audio format. It's much easier to remove that decoder_flush() function and make the decoder thread call ob_flush().
2008-10-29decoder_api: make the audio_format parameter mandatoryMax Kellermann1-5/+3
There are no callers which pass audio_format==NULL, and it shouldn't be allowed.
2008-10-29decoder_api: removed decoder_clear()Max Kellermann1-5/+4
Call ob_clear() in decoder_command_finished() instead of implementing that call in every decoder plugin.
2008-10-29decoder_api: don't cast need_chunks() to intMax Kellermann1-4/+4
need_chunks() returns a decoder_command enum. Store its return value as this type.
2008-10-26input_stream: no CamelCaseMax Kellermann1-3/+3
Renamed all functions and variables.
2008-10-21pcm_utils: added pcm_convert_init()Max Kellermann1-1/+1
Instead of manually calling memset(0) on the pcm_convert_state struct, client code should use a library function from pcm_utils.c. This way, we can change the semantics of the struct easily.
2008-10-21pcm_utils: no CamelCaseMax Kellermann1-5/+5
Renamed all functions which were still in CamelCase.
2008-10-17input_stream: removed nmemb argumentMax Kellermann1-1/+1
The nmemb argument isn't actually useful, and one of nmemb and size was always passed as 1. Remove it.
2008-10-17input: declare struct input_streamMax Kellermann1-3/+5
Provide a struct type which can be forward-declared. The typedef InputStream is deprecated now.
2008-10-08song: removed CamelCaseMax Kellermann1-1/+1
CamelCase is ugly... rename all functions.
2008-10-08use the "bool" data type instead of "int"Max Kellermann1-1/+1
"bool" should be used in C99 programs for boolean values.
2008-10-08don't include os_compat.hMax Kellermann1-0/+2
When there are standardized headers, use these instead of the bloated os_compat.h.
2008-10-08song: converted typedef Song to struct songMax Kellermann1-0/+1
Again, a data type which can be forward-declared.
2008-09-29switch to C99 types, part IIMax Kellermann1-1/+1
Do full C99 integer type conversion in all modules which were not touched by Eric's merged patch.
2008-09-09audio: moved cmpAudioFormat() to audio_format.hMax Kellermann1-1/+1
Rename it to audio_format_equals() and return "true" if they are equal.
2008-09-07audio_format: converted typedef AudioFormat to struct audio_formatMax Kellermann1-1/+1
Get rid of CamelCase, and don't use a typedef, so we can forward-declare it, and unclutter the include dependencies.
2008-08-26renamed player.c to player_control.cMax Kellermann1-1/+1
Give player.c a better name, meaning that the code is used to control the player thread.
2008-08-26renamed decode.h to decoder_control.hMax Kellermann1-1/+1
2008-08-26moved global variable "pc" to player.hMax Kellermann1-1/+1
This is the last of the three variables. Now we don't need playerData.h anymore in most sources.
2008-08-26moved global variable "ob" to outputBuffer.hMax Kellermann1-0/+1
This releases several include file dependencies. As a side effect, "CHUNK_SIZE" isn't defined by decoder_api.h anymore, so we have to define it directly in the plugins which need it. It just isn't worth it to add it to the decoder plugin API.
2008-08-26moved variable "dc" to decode.hMax Kellermann1-0/+1
Now that "dc" is available here, we don't have to pass it to decoder_is_idle() and decoder_is_starting() anymore.
2008-08-26added flag "decoder.seeking"Max Kellermann1-1/+8
This flag is used internally; it is set by decoder_seek_where(), and indicates that the decoder plugin has begun the seek process. It is used for the case that the decoder plugin has to read data during the seek process. Before this patch, that was impossible, because decoder_read() would refuse to read data unless dc->command is NONE. This patch is kind of a dirty workaround, and needs to be redesigned later.
2008-08-26added decoder_read()Max Kellermann1-0/+24
On our way to stabilize the decoder API, we will one day remove the input stream functions. The most basic function, read() will be provided by decoder_api.h with this patch. It already contains a loop (still with manual polling), error/eof handling and decoder command checks. This kind of code used to be duplicated in all decoder plugins.
2008-08-26added decoder_plugin_register()Max Kellermann1-0/+11
With the functions decoder_plugin_register() and decoder_plugin_unregister(), decoder plugins can register a "secondary" plugin, like the flac input plugin does this for "oggflac".
2008-08-26eliminate OUTPUT_BUFFER_DC_STOP, OUTPUT_BUFFER_DC_SEEKMax Kellermann1-11/+11
(Ab)use the decoder_command enumeration, which has nearly the same values and the same meaning.
2008-08-26added decoder_get_url()Max Kellermann1-0/+5
The wavpack decoder plugin implements a hack, and it needs the song URL for that. This API (and the hack) should be revised later, but add that function for now.
2008-08-26added decoder_seek_where() and decoder_seek_error()Max Kellermann1-2/+16
Provide access to seeking for the decoder plugins; they have to know where to seek, and they need a way to tell us that seeking has failed.
2008-08-26added decoder_command_finished() to decoder_api.hMax Kellermann1-3/+12
Some decoder commands are implemented in the decoder plugins, thus they need to have an API call to signal that their current command has been finished. Let them use the new decoder_command_finished() instead of the internal dc_command_finished().
2008-08-26added decoder_get_command()Max Kellermann1-0/+5
Another big patch which hides internal mpd APIs from decoder plugins: decoder plugins regularly poll dc->command; expose it with a decoder_api.h function.
2008-08-26moved convState to struct decoderMax Kellermann1-4/+6
Since we moved all PCM conversions to decoder_data(), the attribute convState isn't being used anymore by the OutputBuffer code. Move it to struct decoder.
2008-08-26moved struct AudioFormat to audio_format.hMax Kellermann1-0/+1
We want to expose the AudioFormat structure to plugins; remove some clutter by moving its declaration to a separate header file.
2008-08-26added parameter total_time to decoder_initialized()Max Kellermann1-1/+4
Similar to the previous patch: pass total_time instead of manipulating dc->totalTime directly.
2008-08-26added audio_format parameter to decoder_initialized()Max Kellermann1-1/+8
dc->audioFormat is set once by the decoder plugins before invoking decoder_initialized(); hide dc->audioFormat and let the decoder pass an AudioFormat pointer to decoder_initialized().
2008-08-26added decoder_clear() and decoder_flush()Max Kellermann1-0/+10
We are now beginning to remove direct structure accesses from the decoder plugins. decoder_clear() and decoder_flush() mask two very common buffer functions.
2008-08-26added decoder_data()Max Kellermann1-0/+80
Moved all of the player-waiting code to decoder_data(), to make OutputBuffer more generic.
2008-08-26added decoder_initialized()Max Kellermann1-6/+9
decoder_initialized() sets the state to DECODE_STATE_DECODE and wakes up the player thread. It is called by the decoder plugin after its internal initialization is finished. More arguments will be added later to prevent direct accesses to the DecoderControl struct.
2008-01-03Cleanup #includes of standard system headers and put them in one placeEric Wong1-2/+0
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
