decoder
decoder demonstrates decoding a ogg file and saving the results to a single file
Instructions
Install decoder
Download and install the decoder
go install github.com/pion/opus/examples/decoder@latest
Create a ogg file to decode
Encode Opus into an ogg file, or use one that you already have. This implementation doesn't support most Opus features yet, so encoding will be constrained.
ffmpeg -i $INPUT_FILE -c:a libopus -ac 1 -b:a 10K output.ogg
Decode
Demux and decode the provided ogg
file. The output audio samples will be saved to disk.
decoder `pwd`/output.ogg `audio-samples.pcm`
Play your audio
Now play the audio with the tool of your choice.
gst-launch-1.0 filesrc location=audio-samples.pcm ! audio/x-raw, format=S16LE, rate=48000,channels=1 ! autoaudiosink -v
ffplay -f s16le -ar 48000 audio-samples.pcm
