* replay_gain: reimplement as a filter pluginMax Kellermann2010-02-171-1/+8
| | | | | | | Apply the replay gain in the output thread. This means a new setting will be active instantly, without going through the whole music pipe. And we might have different replay gain settings for each audio output device.
* replay_gain: refactor API, move code to replay_gain_state.cMax Kellermann2010-01-041-1/+1
| | | | | The replay_gain_state struct holds the precalculated scale factor, which is removed from struct replay_gain_info.
* decoder_api: added function decoder_replay_gain()Max Kellermann2010-01-041-0/+2
| | | | | | This function replaces the replay_gain_info parameter for decoder_data(). This allows the decoder to announce replay gain changes, instead of having to pass the same object over and over.
* Update copyright notices.Avuton Olrich2009-12-311-1/+1

* decoder_api: added function decoder_timestamp()Max Kellermann2009-12-261-0/+5
| | | | | | Remove the data_time parameter from decoder_data(). This patch eliminates the timestamp counting in most decoder plugins, because the MPD core will do it automatically by default.
* decoder_control: removed the global variable "dc"Max Kellermann2009-10-311-0/+2
| | | | | Allocate a decoder_control object where needed, and pass it around. This will allow more than one decoder thread one day.
* decoder_api: submit the song tag to the music pipeMax Kellermann2009-04-131-0/+7
| | | | | | When a new song starts playing, send its tag (song->tag) to the music pipe. This allows output plugins to render tags for all songs, not only those with embedded tags understood by the decoder plugin.
* all: Update copyright header.Avuton Olrich2009-03-131-6/+7
| | | | | | | | This updates the copyright header to all be the same, which is pretty much an update of where to mail request for a copy of the GPL and the years of the MPD project. This also puts all committers under 'The Music Player Project' umbrella. These entries should go individually in the AUTHORS file, for consistancy.
* pipe: added music_buffer, rewrite music_pipeMax Kellermann2009-03-061-7/+6
| | | | | | | | Turn the music_pipe into a simple music_chunk queue. The music_chunk allocation code is moved to music_buffer, and is now managed with a linked list instead of a ring buffer. Two separate music_pipe objects are used by the decoder for the "current" and the "next" song, which greatly simplifies the cross-fading code.
* music_pipe: added music_pipe_push()Max Kellermann2009-03-061-0/+22
| | | | | | | Added music_pipe_allocate(), music_pipe_push() and music_pipe_cancel(). Those functions allow the caller (decoder thread in this case) to do its own chunk management. The functions music_pipe_flush() and music_pipe_tag() can now be removed.
* decoder_api: moved struct decoder_plugin to decoder_plugin.hMax Kellermann2009-02-151-1/+0
| | | | | | The decoder_plugin struct is used by both the MPD core and the decoder plugin implementations. Move it to a shared header file, to minimize header dependencies.
* 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.
* input_stream: added tag() methodMax Kellermann2009-01-031-2/+5
| | | | | The tag() method reads a tag from the stream. This replaces the meta_name and meta_title attributes.
* decoder: removed "plugin" from the decoder structMax Kellermann2008-11-081-2/+0
| | | | decoder.plugin was a write-only attribute.
* decoder_api: automatically send stream tagMax Kellermann2008-11-031-0/+3
| | | | | | | | | | 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.
* decoder: return const decoder_plugin structsMax Kellermann2008-11-011-1/+1
| | | | | The decoder_plugin structs must never change. Don't work with non-const pointers.
* added prefix to header macrosMax Kellermann2008-10-311-2/+2
| | | | | | | "LOG_H" is a macro which is also used by ffmpeg/log.h. This is ffmpeg's fault, because short macros should be reserved for applications, but since it's always a good idea to choose prefixed macro names, even for applications, we are going to do that in MPD.
* pcm_utils: renamed ConvState to struct pcm_convert_stateMax Kellermann2008-10-211-1/+1
| | | | No CamelCase, and a struct instead of a typedef.
* use the "bool" data type instead of "int"Max Kellermann2008-10-081-1/+1
| | | | "bool" should be used in C99 programs for boolean values.
* added flag "decoder.seeking"Max Kellermann2008-08-261-0/+2
| | | | | | | | | | 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.
* renamed InputPlugin to struct decoder_pluginMax Kellermann2008-08-261-1/+1
| | | | | | "decoder plugin" is a better name than "input plugin", since the plugin does not actually do the input - InputStream does. Also don't use typedef, so we can forward-declare it if required.
* moved convState to struct decoderMax Kellermann2008-08-261-0/+3
| | | | | | 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.
* added struct decoderMax Kellermann2008-08-261-0/+28
The decoder struct should later be made opaque to the decoder plugin, because maintaining a stable struct ABI is quite difficult. The ABI should only consist of a small number of stable functions.
