- *
- * Note that (your build of) libmpg123 does not necessarily support all these.
- * Usually, you can expect the 8bit encodings and signed 16 bit.
- * Also 32bit float will be usual beginning with mpg123-1.7.0 .
- * What you should bear in mind is that (SSE, etc) optimized routines may be
- * absent for some formats. We do have SSE for 16, 32 bit and float, though.
- * 24 bit integer is done via postprocessing of 32 bit output -- just cutting
- * the last byte, no rounding, even. If you want better, do it yourself.
- *
- * All formats are in native byte order. If you need different endinaness, you
- * can simply postprocess the output buffers (libmpg123 wouldn't do anything
- * else). The macro MPG123_SAMPLESIZE() can be helpful there.

- I used to have a check here that prevents building for a library with conflicting large file setup
- (application that uses 32 bit offsets with library that uses 64 bits).
- While that was perfectly fine in an environment where there is one incarnation of the library,
- it hurt GNU/Linux and Solaris systems with multilib where the distribution fails to provide the
- correct header matching the 32 bit library (where large files need explicit support) or
- the 64 bit library (where there is no distinction).
-
- New approach: When the app defines _FILE_OFFSET_BITS, it wants non-default large file support,
- and thus functions with added suffix (mpg123_open_64).
- Any mismatch will be caught at link time because of the _FILE_OFFSET_BITS setting used when
- building libmpg123. Plus, there's dual mode large file support in mpg123 since 1.12 now.
- Link failure is not the expected outcome of any half-sane usage anymore.
-
- More complication: What about client code defining _LARGEFILE64_SOURCE? It might want direct access to the _64 functions, along with the ones without suffix. Well, that's possible now via defining MPG123_NO_LARGENAME and MPG123_LARGESUFFIX, respectively, for disabling or enforcing the suffix names.

-/** \defgroup mpg123_output mpg123 output audio format
- *
- * Functions to get and select the format of the decoded audio.
- *
- * Before you dive in, please be warned that you might get confused by this.
- * This seems to happen a lot, therefore I am trying to explain in advance.
- * If you do feel confused and just want to decode your normal MPEG audio files that
- * don't alter properties in the middle, just use mpg123_open_fixed() with a fixed encoding
- * and channel count and forget about a matrix of audio formats. If you want to get funky,
- * read ahead ...
- *
- * The mpg123 library decides what output format to use when encountering the first frame in a stream, or actually any frame that is still valid but differs from the frames before in the prompted output format. At such a deciding point, an internal table of allowed encodings, sampling rates and channel setups is consulted. According to this table, an output format is chosen and the decoding engine set up accordingly (including optimized routines for different output formats). This might seem unusual but it just follows from the non-existence of "MPEG audio files" with defined overall properties. There are streams, streams are concatenations of (semi) independent frames. We store streams on disk and call them "MPEG audio files", but that does not change their nature as the decoder is concerned (the LAME/Xing header for gapless decoding makes things interesting again).
- *
- * To get to the point: What you do with mpg123_format() and friends is to fill the internal table of allowed formats before it is used. That includes removing support for some formats or adding your forced sample rate (see MPG123_FORCE_RATE) that will be used with the crude internal resampler. Also keep in mind that the sample encoding is just a question of choice -- the MPEG frames do only indicate their native sampling rate and channel count. If you want to decode to integer or float samples, 8 or 16 bit ... that is your decision. In a "clean" world, libmpg123 would always decode to 32 bit float and let you handle any sample conversion. But there are optimized routines that work faster by directly decoding to the desired encoding / accuracy. We prefer efficiency over conceptual tidyness.
- *
- * People often start out thinking that mpg123_format() should change the actual decoding format on the fly. That is wrong. It only has effect on the next natural change of output format, when libmpg123 will consult its format table again. To make life easier, you might want to call mpg123_format_none() before any thing else and then just allow one desired encoding and a limited set of sample rates / channel choices that you actually intend to deal with. You can force libmpg123 to decode everything to 44100 KHz, stereo, 16 bit integer ... it will duplicate mono channels and even do resampling if needed (unless that feature is disabled in the build, same with some encodings). But I have to stress that the resampling of libmpg123 is very crude and doesn't even contain any kind of "proper" interpolation.
- *
- * In any case, watch out for MPG123_NEW_FORMAT as return message from decoding routines and call mpg123_getformat() to get the currently active output format.

- *
- * Functions querying and manipulating position in the decoded audio bitstream.
- * The position is measured in decoded audio samples, or MPEG frame offset for the specific functions.
- * If gapless code is in effect, the positions are adjusted to compensate the skipped padding/delay - meaning, you should not care about that at all and just use the position defined for the samples you get out of the decoder;-)
- * The general usage is modelled after stdlib's ftell() and fseek().
- * Especially, the whence parameter for the seek functions has the same meaning as the one for fseek() and needs the same constants from stdlib.h:
- * - SEEK_SET: set position to (or near to) specified offset
- * - SEEK_CUR: change position by offset from now
- * - SEEK_END: set position to offset from end
- *
- * Note that sample-accurate seek only works when gapless support has been enabled at compile time; seek is frame-accurate otherwise.
- * Also, really sample-accurate seeking (meaning that you get the identical sample value after seeking compared to plain decoding up to the position) is only guaranteed when you do not mess with the position code by using MPG123_UPSPEED, MPG123_DOWNSPEED or MPG123_START_FRAME. The first two mainly should cause trouble with NtoM resampling, but in any case with these options in effect, you have to keep in mind that the sample offset is not the same as counting the samples you get from decoding since mpg123 counts the skipped samples, too (or the samples played twice only once)!
- * Short: When you care about the sample position, don't mess with those parameters;-)
- * Also, seeking is not guaranteed to work for all streams (underlying stream may not support it).
- * And yet another caveat: If the stream is concatenated out of differing pieces (Frankenstein stream), seeking may suffer, too.
