* pipe: added music_buffer, rewrite music_pipeMax Kellermann2009-03-061-3/+2
| | | | | | | | 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 Kellermann2009-03-061-1/+5
| | | | | | | 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.
* ls: moved generic URI utilities to uri.cMax Kellermann2009-02-251-1/+1
| | | | | "ls" is a bad name for a library which parses URIs. We'll move the rest of the "ls" library later.
* decoder_api: moved enum decoder_command to decoder_command.hMax Kellermann2009-02-151-0/+3
| | | | Minimize header dependencies, again.
* decoder_plugin: added inline wrapper functionsMax Kellermann2009-02-151-2/+2
| | | | | Increase code readability, always use the wrapper functions instead of calling the plugin method pointers directly.
* decoder_thread: re-enable file decodersMax Kellermann2009-02-111-1/+1
| | | | | By accident, I committed a debug flag, which disallowed the decoder thread to play files locally. Undo this hunk.
* archive: replaced setup_stream() with open_stream()Max Kellermann2009-01-301-1/+1
| | | | | | | The open_stream() method opens the input_stream. This allows the archive plugin to do its own initialization, and it also allows it to use input_stream.data. We can remove input_stream.archive now, which was unnatural to have in the first place.
* decoder_control: added decoder_control.threadMax Kellermann2009-01-251-2/+4
| | | | | decoder_control.thread contains the handle of the decoder thread, or NULL if the decoder thread isn't running.
* pcm: added pcm_convert_deinit(), pcm_resample_deinit()Max Kellermann2009-01-071-0/+4
| | | | | Free memory allocated by libsamplerate when the output or the decoder is closed.
* initialize GError pointersMax Kellermann2009-01-041-1/+1
| | | | | GLib mandates that you initialize all GError objects with NULL prior to passing it.
* song: allocate the result of song_get_url()Max Kellermann2009-01-041-5/+2
|
* ls: renamed functions, no CamelCaseMax Kellermann2009-01-041-2/+2
|
* ls: include cleanupMax Kellermann2009-01-041-0/+3
| | | | | Don't include headers which are not used. Fix some includes in decoder_thread.c.
* input_stream: added tag() methodMax Kellermann2009-01-031-3/+12
| | | | | The tag() method reads a tag from the stream. This replaces the meta_name and meta_title attributes.
* mapper: allocate the result of map_directory_child_fs(), map_song_fs()Max Kellermann2009-01-021-14/+25
| | | | Don't use fixed stack buffers.
* decoder_thread: migrate from pthread to glib threadsThomas Jansen2008-12-281-8/+5
|
* Include <pthread.h> where it is necessary onlyThomas Jansen2008-12-281-0/+1
|
* decoder: terminate decoder thread before MPD cleanupMax Kellermann2008-12-281-2/+2
| | | | | | When MPD exits, it should manually free all resources in use, to allow easy memory leak debugging. Make the decoder thread terminate during that.
* decoder: added missing glib.h includeMax Kellermann2008-11-251-0/+2
|
* decoder_thread.c: replaced mpd_unused by G_GNUC_UNUSEDThomas Jansen2008-11-241-1/+1
|
* decoder: ignore the SEEK command during startupMax Kellermann2008-11-201-1/+1
| | | | | | While waiting for the input stream to become ready, ignore all commands except STOP. This fixes seeking errors with (remote) songs which the decoder has already finished.
* decoder: fixed typo in assertionMax Kellermann2008-11-111-1/+1
| | | | | decoder_file_decode() should check for plugin->file_decode, not plugin->stream_decode().
* decoder: return void from decode() methodsMax Kellermann2008-11-111-26/+8
| | | | | | | | The stream_decode() and file_decode() methods returned a boolean, indicating whether they were able to decode the song. This is redundant, since we already know that: if decoder_initialized() has been called (and dc.state==DECODE), the plugin succeeded. Change both methods to return void.
* decoder: removed plugin method try_decode()Max Kellermann2008-11-101-24/+0
| | | | | | Instead of having a seprate try_decode() method, let the stream_decode() and file_decode() methods decide whether they are able to decode the song.
* decoder: fall back to next pluginMax Kellermann2008-11-101-4/+16
| | | | When a plugin is unable to decode a song, try the other plugins.
* decoder: wrapper functions for methods stream_decode() and file_decode()Max Kellermann2008-11-101-5/+66
| | | | Added lots of assertions to the wrapper functions.
* decoder: converted dc.error to a dc.state valueMax Kellermann2008-11-081-11/+9
| | | | | | The player did not care about the exact error value, it only checked whether an error has occured. This could fit well into decoder_control.state - introduce a new state "DECODE_STATE_ERROR".
* decoder: removed "plugin" from the decoder structMax Kellermann2008-11-081-4/+0
| | | | decoder.plugin was a write-only attribute.
* decoder: removed stream_typesMax Kellermann2008-11-041-8/+0
| | | | | Instead of checking the stream_types bit set, we can simply check whether the methods stream_decode() and file_decode() are implemented.
* decoder: update dc.error after input stream failureMax Kellermann2008-11-031-0/+1
| | | | dc.error wasn't updated when the input stream failed to initialize.
* decoder: no CamelCaseMax Kellermann2008-11-031-19/+19
| | | | Renamed variables and functions.
* decoder_api: automatically send stream tagMax Kellermann2008-11-031-0/+1
| | | | | | | | | | 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: rewind input stream after try_decode()Max Kellermann2008-11-021-1/+8
| | | | | | | | | The try_decode() method may have read some data from the stream, which is now lost. To make this data available to other methods, get it back by rewinding the input stream after each try_decode() invocation. The ogg and wavpack plugins did this manually and inconsistently; this code can now be removed.
* decoder: moved code to decoder_try_decode()Max Kellermann2008-11-021-6/+13
|
* decoder_api: pass "seekable" flag to decoder_initialized()Max Kellermann2008-11-021-3/+0
| | | | | | 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.
* music_pipe: renamed ob_* functions to music_pipe_*Max Kellermann2008-11-021-1/+1
| | | | Rename all functions to the new prefix.
* renamed outputBuffer.[ch] to pipe.[ch]Max Kellermann2008-11-021-1/+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.
* 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.
* update: check return valuesMax Kellermann2008-10-311-8/+12
| | | | | Nearly all mapper functions can fail and will then return NULL. Add checks to all callers.
* decoder: eliminate gotos in decodeStart()Max Kellermann2008-10-311-7/+12
| | | | http://xkcd.com/292/
* decoder: don't wake up player when command==NONEMax Kellermann2008-10-311-1/+0
| | | | | If nobody sent a command, the player isn't waiting for the decoder. Don't wake it up.
* decoder: notify player after stopMax Kellermann2008-10-311-0/+1
| | | | The player should always be woken up when the decoder quits.
* decoder: reset state and command in decoder_task()Max Kellermann2008-10-311-4/+4
| | | | | Eliminate one goto in decodeStart() by moving some cleanup to decoder_task().
* decoder: introduce switch statement in decoder_task()Max Kellermann2008-10-311-4/+10
| | | | | switch looks much nicer than if/elseif/... and gcc generates nice warnings when a new command is added to the enum.
* decoder: use bool for return values and flagsMax Kellermann2008-10-301-9/+8
| | | | | Don't return 0/-1 on success/error, but true/false. Instead of int, use bool for storing flags.
* decoder: automatically flush the output buffer after decoder exitsMax Kellermann2008-10-291-0/+3
| | | | | | | 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().
* input_stream: use "bool" instead of "int"Max Kellermann2008-10-261-1/+1
| | | | | For boolean values and success flags, use bool instead of integer (1/0 for true/false, 0/-1 for success/failure).
* input_stream: no CamelCaseMax Kellermann2008-10-261-5/+5
| | | | Renamed all functions and variables.
* path: removed pathcpy_trunc()Max Kellermann2008-10-201-5/+2
| | | | There was only one user of pathcpy_trunc(), which can be eliminated.
* input: declare struct input_streamMax Kellermann2008-10-171-1/+1
| | | | | Provide a struct type which can be forward-declared. The typedef InputStream is deprecated now.
