Detailed Description

Functions to initialise and shutdown the mpg123 library and handles. The parameters of handles have workable defaults, you only have to tune them when you want to tune something;-) Tip: Use a RVA setting...

Typedef Documentation

◆ mpg123_handle

Opaque structure for the libmpg123 decoder handle. Most functions take a pointer to a mpg123_handle as first argument and operate on its data in an object-oriented manner.

Definition at line 140 of file mpg123.h.

Enumeration Type Documentation

◆ mpg123_feature_set

Feature set available for query with mpg123_feature.

304 {
323 };

◆ mpg123_param_flags

Flag bits for MPG123_FLAGS, use the usual binary or to combine.

Enumerator
MPG123_FORCE_MONO 

0111 Force some mono mode: This is a test bitmask for seeing if any mono forcing is active.

MPG123_MONO_LEFT 

0001 Force playback of left channel only.

MPG123_MONO_RIGHT 

0010 Force playback of right channel only.

MPG123_MONO_MIX 

0100 Force playback of mixed mono.

MPG123_FORCE_STEREO 

1000 Force stereo output.

MPG123_FORCE_8BIT 

00010000 Force 8bit formats.

MPG123_QUIET 

00100000 Suppress any printouts (overrules verbose).

MPG123_GAPLESS 

01000000 Enable gapless decoding (default on if libmpg123 has support).

MPG123_NO_RESYNC 

10000000 Disable resync stream after error.

MPG123_SEEKBUFFER 

000100000000 Enable small buffer on non-seekable streams to allow some peek-ahead (for better MPEG sync).

MPG123_FUZZY 

001000000000 Enable fuzzy seeks (guessing byte offsets or using approximate seek points from Xing TOC)

MPG123_FORCE_FLOAT 

010000000000 Force floating point output (32 or 64 bits depends on mpg123 internal precision).

MPG123_PLAIN_ID3TEXT 

100000000000 Do not translate ID3 text data to UTF-8. ID3 strings will contain the raw text data, with the first byte containing the ID3 encoding code.

MPG123_IGNORE_STREAMLENGTH 

1000000000000 Ignore any stream length information contained in the stream, which can be contained in a 'TLEN' frame of an ID3v2 tag or a Xing tag

MPG123_SKIP_ID3V2 

10 0000 0000 0000 Do not parse ID3v2 tags, just skip them.

MPG123_IGNORE_INFOFRAME 

100 0000 0000 0000 Do not parse the LAME/Xing info frame, treat it as normal MPEG data.

MPG123_AUTO_RESAMPLE 

1000 0000 0000 0000 Allow automatic internal resampling of any kind (default on if supported). Especially when going lowlevel with replacing output buffer, you might want to unset this flag. Setting MPG123_DOWNSAMPLE or MPG123_FORCE_RATE will override this.

MPG123_PICTURE 

17th bit: Enable storage of pictures from tags (ID3v2 APIC).

MPG123_NO_PEEK_END 

18th bit: Do not seek to the end of the stream in order to probe the stream length and search for the id3v1 field. This also means the file size is unknown unless set using mpg123_set_filesize() and the stream is assumed as non-seekable unless overridden.

MPG123_FORCE_SEEKABLE 

19th bit: Force the stream to be seekable.

MPG123_STORE_RAW_ID3 

store raw ID3 data (even if skipping)

MPG123_FORCE_ENDIAN 

Enforce endianess of output samples. This is not reflected in the format codes. If this flag is set along with MPG123_BIG_ENDIAN, MPG123_ENC_SIGNED16 means s16be, without MPG123_BIG_ENDIAN, it means s16le. Normal operation without MPG123_FORCE_ENDIAN produces output in native byte order.

MPG123_BIG_ENDIAN 

Choose big endian instead of little.

MPG123_NO_READAHEAD 

Disable read-ahead in parser. If you know you provide full frames to the feeder API, this enables decoder output from the first one on, instead of having to wait for the next frame to confirm that the stream is healthy. It also disables free format support unless you provide a frame size using MPG123_FREEFORMAT_SIZE.

MPG123_FLOAT_FALLBACK 

Consider floating point output encoding only after trying other (possibly downsampled) rates and encodings first. This is to support efficient playback where floating point output is only configured for an external resampler, bypassing that resampler when the desired rate can be produced directly. This is enabled by default to be closer to older versions of libmpg123 which did not enable float automatically at all. If disabled, float is considered after the 16 bit default and higher-bit integer encodings for any rate.

MPG123_NO_FRANKENSTEIN 

Disable support for Frankenstein streams (different MPEG streams stiched together). Do not accept serious change of MPEG header inside a single stream. With this flag, the audio output format cannot change during decoding unless you open a new stream. This also stops decoding after an announced end of stream (Info header contained a number of frames and this number has been reached). This makes your MP3 files behave more like ordinary media files with defined structure, rather than stream dumps with some sugar.

◆ mpg123_param_rva

choices for MPG123_RVA

Enumerator
MPG123_RVA_OFF 

RVA disabled (default).

MPG123_RVA_MIX 

Use mix/track/radio gain.

MPG123_RVA_ALBUM 

Use album/audiophile gain

MPG123_RVA_MAX 

The maximum RVA code, may increase in future.

Definition at line 272 of file mpg123.h.

◆ mpg123_parms

Enumeration of the parameters types that it is possible to set/get.

Enumerator
MPG123_VERBOSE 

set verbosity value for enabling messages to stderr, >= 0 makes sense (integer)

MPG123_FLAGS 

set all flags, p.ex val = MPG123_GAPLESS|MPG123_MONO_MIX (integer)

MPG123_ADD_FLAGS 

add some flags (integer)

MPG123_FORCE_RATE 

when value > 0, force output rate to that value (integer)

MPG123_DOWN_SAMPLE 

0=native rate, 1=half rate, 2=quarter rate (integer)

MPG123_RVA 

one of the RVA choices above (integer)

MPG123_DOWNSPEED 

play a frame N times (integer)

MPG123_UPSPEED 

play every Nth frame (integer)

MPG123_START_FRAME 

start with this frame (skip frames before that, integer)

MPG123_DECODE_FRAMES 

decode only this number of frames (integer)

MPG123_ICY_INTERVAL 

Stream contains ICY metadata with this interval (integer). Make sure to set this before opening a stream.

MPG123_OUTSCALE 

the scale for output samples (amplitude - integer or float according to mpg123 output format, normally integer)

MPG123_TIMEOUT 

timeout for reading from a stream (not supported on win32, integer)

MPG123_REMOVE_FLAGS 

remove some flags (inverse of MPG123_ADD_FLAGS, integer)

MPG123_RESYNC_LIMIT 

Try resync on frame parsing for that many bytes or until end of stream (<0 ... integer). This can enlarge the limit for skipping junk on beginning, too (but not reduce it).

MPG123_INDEX_SIZE 

Set the frame index size (if supported). Values <0 mean that the index is allowed to grow dynamically in these steps (in positive direction, of course) – Use this when you really want a full index with every individual frame.

MPG123_PREFRAMES 

Decode/ignore that many frames in advance for layer 3. This is needed to fill bit reservoir after seeking, for example (but also at least one frame in advance is needed to have all "normal" data for layer 3). Give a positive integer value, please.

MPG123_FEEDPOOL 

For feeder mode, keep that many buffers in a pool to avoid frequent malloc/free. The pool is allocated on mpg123_open_feed(). If you change this parameter afterwards, you can trigger growth and shrinkage during decoding. The default value could change any time. If you care about this, then set it. (integer)

MPG123_FEEDBUFFER 

Minimal size of one internal feeder buffer, again, the default value is subject to change. (integer)

MPG123_FREEFORMAT_SIZE 

Tell the parser a free-format frame size to avoid read-ahead to get it. A value of -1 (default) means that the parser will determine it. The parameter value is applied during decoder setup for a freshly opened stream only.

◆ mpg123_feature2()

MPG123_EXPORT int mpg123_feature2 ( int  key)

Query libmpg123 features with better ABI compatibility

This is the same as mpg123_feature(), but this time not using the enum as argument. Compilers don't have to agree on the size of enums and hence they are not safe in public API.

Parameters
keyfeature selection
Returns
1 for success, 0 for unimplemented functions

MPG123_EXPORT void mpg123_free ( void ptr)

Free plain memory allocated within libmpg123. This is for library users that are not sure to use the same underlying memory allocator as libmpg123. It is just a wrapper over free() in the underlying C library.

◆ mpg123_new()

MPG123_EXPORT mpg123_handle* mpg123_new ( const char decoder,
int error 
)

Create a handle with optional choice of decoder (named by a string, see mpg123_decoders() or mpg123_supported_decoders()). and optional retrieval of an error code to feed to mpg123_plain_strerror(). Optional means: Any of or both the parameters may be NULL.

Parameters
decoderoptional choice of decoder variant (NULL for default)
erroroptional address to store error codes
Returns
Non-NULL pointer to fresh handle when successful.
