Crate opus_embedded_sys 

Minimal bindings for opus decoder.

Focused on no_alloc use on embedded ARM platforms.

The documentation is not very well-formatted in places and you might want to look at Opus documentation instead instead. In particular, the page about Opus Decoder may be handy.

Structs

OpusDecoder

Struct big enough to contain OpusDecoder of opus-1.5.2 so it can be reserved on stack.

Functions

opus_decode^⚠

Decode an Opus packet.

opus_decoder_create^⚠

Allocates and initializes a decoder state.

opus_decoder_destroy^⚠

Frees an OpusDecoder allocated by opus_decoder_create().

opus_decoder_get_nb_samples^⚠

Gets the number of samples of an Opus packet.

opus_decoder_get_size^⚠

Gets the size of an OpusDecoder structure.

opus_decoder_init^⚠

Initializes a previously allocated decoder state. The state must be at least the size returned by opus_decoder_get_size(). This is intended for applications which use their own allocator instead of malloc. See also opus_decoder_create and opus_decoder_get_size. To reset a previously initialized state, use the OPUS_RESET_STATE CTL.

opus_packet_get_bandwidth^⚠

Gets the bandwidth of an Opus packet.

opus_packet_get_nb_channels^⚠

Gets the number of channels from an Opus packet.

opus_packet_get_nb_frames^⚠

Gets the number of frames in an Opus packet.

opus_packet_get_nb_samples^⚠

Gets the number of samples of an Opus packet.

opus_packet_get_samples_per_frame^⚠

Gets the number of samples per frame from an Opus packet.

opus_strerror^⚠

Converts an opus error code into a human readable string.
