Sorry if this is the wrong place for this, but I didnt see a dedicated category for the aiortc client and didn’t want to create an issue in the repo.
I am wondering if there is any way to simply loop the input file being used. I poked around the aiortc repo a bit but I am not great with python, but it looks like the media player provides simple start/stop functionality. I’m not sure if just issuing a stop/start would reset the timestamps/frames used by the underlying player process.
I am trying to write a light-weight test client for load testing, and I want each client to run indefinitely and actually provide valid audio data while active. This will help me to profile and generate load graphs as I connect/disconnect different numbers of clients. I was hoping to just be able to use a simple 16 second mp4 sample for this rather than needing to use some larger ~30 min audio sample.
I also tried something like this, but it didn’t quite work:
let producer = null;
for (let i = 0; i < 3; i++) {
console.log(`Playback count: ${i + 1}`);
const stream = await worker.getUserMedia({
video: false,
audio: {
source: 'file',
file: testFilePath,
},
});
const track = stream.getAudioTracks()[0];
if (!producer) {
producer = await sendTransport.produce({
track,
paused: false,
codecOptions: {
opusFec: true,
opusDtx: true,
opusMaxPlaybackRate: 48000,
},
});
} else {
await producer.replaceTrack({track});
}
await Promise.delay(18000);
track.stop();
stream.close();
}
producer.close();
sendTransport.close();
recvTransport.close();
It did work if I instead created an entirely new producer instead of using replaceTrack but that introduces additional code-paths (managing the producers in my server application code) that I don’t really want involved in this testing scenario.
Just wondering if you had any thoughts/suggestions on this.
Thanks, this client is really cool and exactly what I needed for automated testing.
