dca is a audio file format that uses opus packets and json metadata.
This package implements a decoder, encoder and a helper streamer for dca v0 and v1.
There's also a standalone command you can use here
Encoding
// Encoding a file and saving it to disk
encodeSession := dca.EncodeFile("path/to/file.mp3", dca.StdEncodeOptions)
// Make sure everything is cleaned up, that for example the encoding process if any issues happened isnt lingering around
defer encodeSession.Cleanup()
output, err := os.Create("output.dca")
if err != nil {
// Handle the error
}
io.Copy(output, encodeSession)Decoding, the decoder automatically detects dca version aswell as if metadata was available
// inputReader is an io.Reader, like a file for example
decoder := dca.NewDecoder(inputReader)
for {
frame, err := decoder.OpusFrame()
if err != nil {
if err != io.EOF {
// Handle the error
}
break
}
// Do something with the frame, in this example were sending it to discord
