We avoid this by adding ## dummy dependencies for each header file. Too bad gcc doesn't do ## this for us directly. ## Some versions of gcc put a space before the ':'.

The libopusfile package provides a convenient high-level API for decoding and basic manipulation of all Ogg Opus audio streams. libopusfile is implemented as a layer on top of Xiph.Org's reference libogg and libopus libraries. libopusfile provides several sets of built-in routines for file/stream access, and may also use custom stream I/O routines provided by the embedded environment. There are built-in I/O routines provided for ANSI-compliant stdio (FILE *), memory buffers, and URLs (including URLs, plus optionally and URLs). \section Organization The main API is divided into several sections: - \ref stream_open_close - \ref stream_info - \ref stream_decoding - \ref stream_seeking Several additional sections are not tied to the main API. - \ref stream_callbacks - \ref header_info - \ref error_codes \section Overview The libopusfile API always decodes files to 48 kHz. The original sample rate is not preserved by the lossy compression, though it is stored in the header to allow you to resample to it after decoding (the libopusfile API does not currently provide a resampler, but the the Speex resampler is a good choice if you need one). In general, if you are playing back the audio, you should leave it at 48 kHz, provided your audio hardware supports it. When decoding to a file, it may be worth resampling back to the original sample rate, so as not to surprise users who might not expect the sample rate to change after encoding to Opus and decoding. Opus files can contain anywhere from 1 to 255 channels of audio. The channel mappings for up to 8 channels are the same as the Vorbis mappings. A special stereo API can convert everything to 2 channels, making it simple to support multichannel files in an application which only has stereo output. Although the libopusfile ABI provides support for the theoretical maximum number of channels, the current implementation does not support files with more than 8 channels, as they do not have well-defined channel mappings. Like all Ogg files, Opus files may be "chained". That is, multiple Opus files may be combined into a single, longer file just by concatenating the original files. This is commonly done in internet radio streaming, as it allows the title and artist to be updated each time the song changes, since each link in the chain includes its own set of metadata. libopusfile fully supports chained files. It will decode the first Opus stream found in each link of a chained file (ignoring any other streams that might be concurrently multiplexed with it, such as a video stream). The channel count can also change between links. If your application is not prepared to deal with this, it can use the stereo API to ensure the audio from all links will always get decoded into a common format. Since libopusfile always decodes to 48 kHz, you do not have to worry about the sample rate changing between links (as was possible with Vorbis). This makes application support for chained files with libopusfile very easy.*/ # if defined(__cplusplus) extern "C" { # endif # include # include # include # include /**@cond PRIVATE*/ /*Enable special features for gcc and gcc-compatible compilers.*/ # if !defined(OP_GNUC_PREREQ) # if defined(__GNUC__)&&defined(__GNUC_MINOR__) # define OP_GNUC_PREREQ(_maj,_min) \ ((__GNUC__<<16)+__GNUC_MINOR__>=((_maj)<<16)+(_min)) # else # define OP_GNUC_PREREQ(_maj,_min) 0 # endif # endif # if OP_GNUC_PREREQ(4,0) # pragma GCC visibility push(default) # endif typedef struct OpusHead OpusHead; typedef struct OpusTags OpusTags; typedef struct OpusPictureTag OpusPictureTag; typedef struct OpusServerInfo OpusServerInfo; typedef struct OpusFileCallbacks OpusFileCallbacks; typedef struct OggOpusFile OggOpusFile; /*Warning attributes for libopusfile functions.*/ # if OP_GNUC_PREREQ(3,4) # define OP_WARN_UNUSED_RESULT __attribute__((__warn_unused_result__)) # else # define OP_WARN_UNUSED_RESULT # endif # if OP_GNUC_PREREQ(3,4) # define OP_ARG_NONNULL(_x) __attribute__((__nonnull__(_x))) # else # define OP_ARG_NONNULL(_x) # endif /**@endcond*/ /**\defgroup error_codes Error Codes*/ /*@{*/ /**\name List of possible error codes Many of the functions in this library return a negative error code when a function fails.

Seeking is implemented for all built-in stream I/O routines, though some individual sources may not be seekable (pipes, live HTTP streams, or HTTP streams from a server that does not support Range requests). op_raw_seek() is the fastest: it is guaranteed to perform at most one physical seek, but, since the target is a byte position, makes no guarantee how close to a given time it will come. op_pcm_seek() provides sample-accurate seeking. The number of physical seeks it requires is still quite small (often 1 or 2, even in highly variable bitrate streams). Seeking in Opus requires decoding some pre-roll amount before playback to allow the internal state to converge (as if recovering from packet loss). This is handled internally by libopusfile, but means there is little extra overhead for decoding up to the exact position requested (since it must decode some amount of audio anyway). It also means that decoding after seeking may not return exactly the same values as would be obtained by decoding the stream straight through.

The general functions, op_read() and op_read_float() return 16-bit or floating-point output, both using native endian ordering. The number of channels returned can change from link to link in a chained stream. There are special functions, op_read_stereo() and op_read_float_stereo(), which always output two channels, to simplify applications which do not wish to handle multichannel audio. These downmix multichannel files to two channels, so they can always return samples in the same format for every link in a chained file. If the rest of your audio processing chain can handle floating point, the floating-point routines should be preferred, as they prevent clipping and other issues which might be avoided entirely if, e.g., you scale down the volume at some other stage. However, if you intend to consume 16-bit samples directly, the conversion in libopusfile provides noise-shaping dithering and, if compiled against libopus 1.1 or later, soft-clipping prevention. libopusfile can also be configured at compile time to use the fixed-point libopus API. If so, libopusfile's floating-point API may also be disabled. In that configuration, nothing in libopusfile will use any floating-point operations, to simplify support on devices without an adequate FPU. \warning HTTPS streams may be be vulnerable to truncation attacks if you do not check the error return code from op_read_float() or its associated functions.

This lets us operate on the full, valid range of granule positions in a consistent and safe manner. This full range is organized into distinct regions: [ -1 (invalid) ][ 0 ... OP_INT64_MAX ][ OP_INT64_MIN ... -2 ][-1 (invalid) ] No one should actually use granule positions so large that they're negative, even if they are technically valid, as very little software handles them correctly (including most of Xiph.Org's). This library also refuses to support durations so large they won't fit in a signed 64-bit integer (to avoid exposing this mess to the application, and to simplify a good deal of internal arithmetic), so the only way to use them successfully is if pcm_start is very large. This means there isn't anything you can do with negative granule positions that you couldn't have done with purely non-negative ones.

The noise shaping filters were designed by Sebastian Gesemann, and are based on the LAME ATH curves with flattening to limit their peak gain to 20 dB. Everyone else's noise shaping filters are mildly crazy. The 48 kHz version of this filter is just a warped version of the 44.1 kHz filter and probably could be improved by shifting the HF shelf up in frequency a little bit, since 48 kHz has a bit more room and being more conservative against bat-ears is probably more important than more noise suppression. This process can increase the peak level of the signal (in theory by the peak error of 1.5 +20 dB, though that is unobservably rare). To avoid clipping, the signal is attenuated by a couple thousandths of a dB. Initially, the approach taken here was to only attenuate by the 99.9th percentile, making clipping rare but not impossible (like SoX), but the limited gain of the filter means that the worst case was only two thousandths of a dB more, so this just uses the worst case. The attenuation is probably also helpful to prevent clipping in the DAC reconstruction filters or downstream resampling, in any case.*/ # define OP_GAIN (32753.0F) # define OP_PRNG_GAIN (1.0F/0xFFFFFFFF) /*48 kHz noise shaping filter, sd=2.34.*/ static const float OP_FCOEF_B[4]={ 2.2374F,-0.7339F,-0.1251F,-0.6033F }; static const float OP_FCOEF_A[4]={ 0.9030F,0.0116F,-0.5853F,-0.2571F }; static int op_float2short_filter(OggOpusFile *_of,void *_dst,int _dst_sz, float *_src,int _nsamples,int _nchannels){ opus_int16 *dst; int ci; int i; dst=(opus_int16 *)_dst; if(OP_UNLIKELY(_nsamples*_nchannels>_dst_sz))_nsamples=_dst_sz/_nchannels; # if defined(OP_SOFT_CLIP) if(_of->state_channel_count!=_nchannels){ for(ci=0;ci<_nchannels;ci++)_of->clip_state[ci]=0; } opus_pcm_soft_clip(_src,_nsamples,_nchannels,_of->clip_state); # endif if(_of->dither_disabled){ for(i=0;i<_nchannels*_nsamples;i++){ dst[i]=op_float2int(OP_CLAMP(-32768,32768.0F*_src[i],32767)); } } else{ opus_uint32 seed; int mute; seed=_of->dither_seed; mute=_of->dither_mute; if(_of->state_channel_count!=_nchannels)mute=65; /*In order to avoid replacing digital silence with quiet dither noise, we mute if the output has been silent for a while.*/ if(mute>64)memset(_of->dither_a,0,sizeof(*_of->dither_a)*4*_nchannels); for(i=0;i<_nsamples;i++){ int silent; silent=1; for(ci=0;ci<_nchannels;ci++){ float r; float s; float err; int si; int j; s=_src[_nchannels*i+ci]; silent&=s==0; s*=OP_GAIN; err=0; for(j=0;j<4;j++){ err+=OP_FCOEF_B[j]*_of->dither_b[ci*4+j] -OP_FCOEF_A[j]*_of->dither_a[ci*4+j]; } for(j=3;j-->0;)_of->dither_a[ci*4+j+1]=_of->dither_a[ci*4+j]; for(j=3;j-->0;)_of->dither_b[ci*4+j+1]=_of->dither_b[ci*4+j]; _of->dither_a[ci*4]=err; s-=err; if(mute>16)r=0; else{ seed=op_rand(seed); r=seed*OP_PRNG_GAIN; seed=op_rand(seed); r-=seed*OP_PRNG_GAIN; } /*Clamp in float out of paranoia that the input will be > 96 dBFS and wrap if the integer is clamped.*/ si=op_float2int(OP_CLAMP(-32768,s+r,32767)); dst[_nchannels*i+ci]=(opus_int16)si; /*Including clipping in the noise shaping is generally disastrous: the futile effort to restore the clipped energy results in more clipping.
