muxable/transcoder

This package implements a transcoding server. It accepts WebRTC signalled over gRPC and will respond with a transcoded track for each received track.

Are you interested in livestreaming video with WebRTC? Join us at Muxable!

Client SDK

For convenience if you don't want to deal with signalling and reconnection semantics, a lightweight client SDK is provided.

Example usage

import "github.com/muxable/transcoder/pkg/transcoder"

...

conn, err := grpc.Dial("localhost:50051", grpc.WithTransportCredentials(insecure.NewCredentials()))
if err != nil {
    return err
}

client, err := transcoder.NewClient(context.Background(), conn)
if err != nil {
    return err
}

transcoded, err := client.Transcode(track)
if err != nil {
    return err
}

Here, client.Transcode() accepts a TrackLocal and returns a TrackRemote. The mime type of the output track can also be specified, for example:

transcoded, err := client.Transcode(track, transcode.ToMimeType(webrtc.MimeTypeVP9))

Cloud hosting

If you are interested in using this service pre-deployed, please email kevin@muxable.com. We are exploring offering endpoints as a paid service.

Debugging

The transcoding server uses GStreamer under the hood. To view debug messages from GStreamer, set GST_DEBUG=3.
