Don't store tag type values in a plain integer, use the proper enum.
|
|
Replace deprecated code with GLib.
|
|
Instead of manually waiting for the input stream to become ready (to
catch server errors), just read the first byte. Since the
wavpack_input has the capability to push back one byte, we can simply
re-feed it. Advantage is: decoder_read() handles everything for us,
i.e. waiting for the stream, polling for decoder commands and error
handling.
|
|
Use boolean true/false instead of 1/0.
|
|
Renamed functions and variables.
|
|
Fixed the indent of the switch statement in format_samples_int().
|
|
Eliminate a superfluous decoder_get_command() call. decoder_data()
already returns the command.
|
|
Removed the duplicate audio_format initialization.
|
|
decoder_read() handles decoder commands, and should be used in decoder
plugins.
|
|
We need the decoder object, so we have to begin passing a new struct
to these callbacks, instead of only the pointer to the input_stream
object.
|
|
Replace deprecated code with GLib.
|
|
The API of mp4_load_tag() was strange: it always returned a tag
object, no matter if a tag was found in the file; the existence of a
tag was indicated with the tag_found integer reference. This flag is
superfluous, since we can simply check whether the tag is empty or
not.
|
|
Allocate the mp4ff_callback_t object on the stack. This is easier to
handle, since we don't have to free it. Incidentally, this fixes a
memory leak in mp4_load_tag().
|
|
Renamed functions and variables.
|
|
The function decoder_read() already cares about the decoder command,
and loops until data is available. Reduced mpd_ffmpeg_read() to no
more than the decoder_read() call.
|
|
That variable is never used except during initialization in
ffmpeg_helper().
|
|
|
|
Renamed variables.
|
|
|
|
Fix prototypes and unused variables.
|
|
The OS X output plugin wasn't adapted to the new output plugin yet,
because I had no Mac to test...
|
|
dc.error wasn't updated when the input stream failed to initialize.
|
|
The function curl_multi_info_read() provides access to errors from the
curl easy interface.
|
|
|
|
Removed the "volatile" attributes from several variables which are not
important for synchronization.
|
|
Renamed variables and internal functions. Most of the
player_control.h API remains in CamelCase for now.
|
|
|
|
The variable "next_song" is already protected by a memory barrier.
"total_time" is not important for synchronization, and we don't need
"volatile" here.
|
|
Renamed variables and functions.
|
|
Before passing the first chunk to the audio output device, send the
current song's tag.
|
|
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.
|
|
tag_has_type() checks whether the tag contains one or more items with
the specified type.
|
|
Renamed variables.
|
|
MPD used to have a copy of the mp4ff library. Since that has been
removed, AAC suport was disabled when there was no libmp4ff. Separate
the libmp4ff test, and enable AAC support no matter if libmp4ff is
available.
|
|
When using autodetection, AlsaData.device wasn't properly initialized
with NULL. This broke autodetection randomly.
|
|
The variables mod_mikModInitiated and mod_mikModInitError were used to
control lazy initialization, but they are superfluous now.
|
|
The "mod" decoder plugin was being initialized lazily, but was
deinitialized unconditionally. That led to segmentation faults.
Convert mod_initMikMod() to be the global module initialization
method. The MPD core should care about lazy initialization.
|
|
Nobody should call playAudio() with an empty chunk. Add some
assertions on that.
|
|
An empty chunk may happen when it only contains a tag, but no PCM
data. Don't call playAudio() then.
|
|
ffmpeg_tag() deleted the tag when ffmpeg_helper() returned success.
The return value was interpreted incorrectly, it should return the tag
on success.
|
|
Cleaning up artifacts from a merge gone wrong. Also remove the
ringbuf library, which is not being used.
|
|
Non-local songs used to have no tags. If the decoder sends us a tag,
we should incorporate it into the song struct. This way, clients can
always show the correct song name (if provided by the server).
|
|
Always remember which song is currently being sent to the audio
device.
|
|
Rewinding the stream here is not useful, but may consume valuable
resources (and time).
|
|
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.
|
|
|
|
If a chunk contains a tag, send it to the audio output device. Few
output plugins support this, e.g. shout has support for sending tags.
|
|
If the source chunk has a tag, merge it into the destination chunk.
The source chunk gets deleted after that, and this is our last chance
to grab the tag.
|
|
decoder_read() checks the decoder command. Without this patch, the
ffmpeg plugin could become unresponsive.
|
|
Ogg and ffmpeg detection was disabled when the stream was not
seekable, because the detection was too expensive. Since the curl
input stream can now rewind the stream cheaply, we can re-enable
detection on streams.
