2009-08-13decoder_control: protect command, state with a mutexMax Kellermann1-2/+25
Replace decoder_control.notify with decoder_control.mutex and decoder_control.cond. Lock the mutex on all accesses to decoder_control.command and decoder_control.state.
2009-03-13all: Update copyright header.Avuton Olrich1-3/+4
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.
2009-03-07decoder_internal: don't push empty chunk into pipeMax Kellermann1-1/+6
When the decoder chunk is empty in decoder_flush_chunk(), don't push it into the music pipe - return it to the music buffer instead. An empty chunk in the pipe wastes resources for no advantage.
2009-03-06pipe: added music_buffer, rewrite music_pipeMax Kellermann1-19/+17
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.
2009-03-06music_pipe: added music_pipe_push()Max Kellermann1-0/+80
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.
