opus-ada

Ada 2012 bindings for the Opus audio codec.

Status

Only the encoder and decoder have been binded. The TODO shows some few functions that are yet to be binded. Some other functions like opus_encoder_get_size, opus_encoder_init, opus_decoder_get_size, and opus_decoder_init will never be binded at all. Other function may or may not be binded in the future. These are: opus_repacketizer_*, opus_multistream_*, and opus_packet_*.

Tasking

The Opus.Encoders.Encoder_Data and Opus.Decoders.Decoder_Data are not designed to be used by multiple tasks.

TODO

• Write some tests for Opus.Encoder.Encode and Opus.Decoder.Decode
• Bind opus_decode_float and opus_encode_float
• Bind opus_decoder_get_nb_samples and opus_pcm_soft_clip

Dependencies

In order to build the library, you need to have:

• An Ada 2012 compiler

• Alire package manager

• Ahven 2.x for the unit tests
