Sample

For source code example, check the sample app directory. On first launch, you will have to set SRT server IP in the settings menu.

Quick start with a FFmpeg SRT server

FFmpeg has been used as an SRT server+demuxer+decoder for the tests. Check how to build FFmpeg with libsrt in SRT CookBook. Tells FFplay to listen on IP 0.0.0.0 and port 9998:

ffplay -fflags nobuffer srt://0.0.0.0:9998?mode=listener

On StreamPack sample app settings, set the server IP to your server IP and server port to 9998. At this point, StreamPack sample app should successfully sends audio and video frames. On FFplay side, you should be able to watch this stream.

API

Captures your camera and microphone frames. Streams them to a SRT server. It is that simple:

// Prepare A/V configurations
val audioConfig = AudioConfig.Builder()
                      .setStartBitrate(128000)
                      .setSampleRate(48000)
                      .setNumberOfChannel(2)
                      .build()

val videoConfig = VideoConfig.Builder()
                    .setStartBitrate(1000000) // 1 Mb/s
                    .setResolution(Size(1280,720))
                    .setFps(30)
                    .build()

val streamer = CameraSrtLiveStreamer.Builder()
                .setContext(getApplication())
                .setServiceInfo(tsServiceInfo)
                .setConfiguration(audioConfig, videoConfig)
                .build()
...
// where to display preview
streamer.startPreview(surface)
...
// Connect to a SRT server
streamer.connect(ip, port)
...
streamer.startStream()
...
// Stops and cleans stream
streamer.stopStream()
...
streamer.disconnect()
...
streamer.stopPreview()
...
streamer.release()
