This is usually caused by a multistream Ogg packet where the durations of the individual Opus packets

EVERSION - The ID header contained an unrecognized version numberĪn audio packet failed to decode properly.

EBADHEADER - A required header packet was not properly formatted, contained illegal values, or was missing altogether.

"OpusTags", or a link in a chained file was encountered that did not contain any logical Opus streams.

EINVAL - One or more parameters to a function were invalid.Ī purported Ogg Opus stream did not begin with an Ogg page, a purported header packet did not start with one of the required strings, "OpusHead" or.

EIMPL - The stream used a feature that is not implemented, such as an unsupported channel family.

EFAULT - A NULL pointer was passed where one was unexpected, or an internal memory allocation failed, or an internal library error was encountered.

EREAD - An underlying read, seek, or tell operation failed when it should have succeeded.

HOLE - There was a hole in the page sequence numbers (e.g., a page was corrupt or missing).

This makes application support for chained files with libopusfile very easy. Since libopusfile always decodes to 48 kHz, you do not have to worry about the sample rateĬhanging between links (as was possible with Vorbis). If your application is not prepared to deal with this, it can use the stereo API to ensure the audioįrom all links will always get decoded into a common format. The channel count can also change between links. Might be concurrently multiplexed with it, such as a video stream). It will decode the first Opus stream found in each link of a chained file (ignoring any other streams that Libopusfile fully supports chained files. This is commonly done in internet radio streaming, as it allows the title and artist to be updated each time the song changes, sinceĮach link in the chain includes its own set of metadata.

That is, multiple Opus files may be combined into a single, longer file just by concatenating the

Like all Ogg files, Opus files may be "chained". Although the libopusfile ABI provides supportįor the theoretical maximum number of channels, the current implementation does not support files with more than 8 channels, as they do not have A special stereo API can convert everything to 2Ĭhannels, making it simple to support multichannel files in an application which only has stereo output. The channel mappings for up to 8 channels are the same as the Opus files can contain anywhere from 1 to 255 channels of audio. 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 In general, if you are playing back the audio, you should leave it at 48 kHz, provided your audio hardware supports it. The Speex resampler is a good choice if you need Header to allow you to resample to it after decoding (the libopusfile API does not currently provide a resampler, but the The original sample rate is not preserved by the lossy compression, though it is stored in the The libopusfile API always decodes files to 48 kHz. Several additional sections are not tied to the main API.

The main API is divided into several sections:

There are built-in I/O routines provided for ANSI-compliant stdio ( FILE *), memory buffers, and URLs (includingįile: URLs, plus optionally http: and https: URLs). Libopusfile provides several sets of built-in routines for file/stream access, and may also use custom stream I/O routines provided by the embeddedĮnvironment.

Implemented as a layer on top of Xiph.Org's reference libogg and The libopusfile package provides a convenient high-level API for decoding and basic manipulation of all Ogg Opus audio streams. This is the documentation for the libopusfile C API. IF you have more questions please comment I will respond as soon as possible.
