Streaming using elevenlabs.generate is not working

[DeeRock94]

Following your recent documentation on the README, it states streaming generated audio can be done via the below:

I've attempted to achieve this with the code below

    const audioStream = await elevenlabs.generate({
        stream: true,
        voice: "Liam",
        text: "This is a... streaming voice",
        model_id: "eleven_multilingual_v2"
    });

    stream(audioStream)

This doesn't seem to work, now when I am using play() and playing it directly, with the stream: false set (or not defined), it works fine, however the second I go to stream it, it seems to throw an error in my node application:

node:internal/process/promises:288
            triggerUncaughtException(err, true /* fromPromise */);
            ^

[UnhandledPromiseRejection: This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). The promise rejected with the reason "null".] {
  code: 'ERR_UNHANDLED_REJECTION'
}

Node.js v18.12.1

Any suggestions? I've attempted to try and catch this error but I can't seem to find anything of value from it.

Update:

Okay so I've managed to get a more specific error than just "null"

node:internal/process/promises:288
            triggerUncaughtException(err, true /* fromPromise */);
            ^

Hey @DeeRock94 -- we'll follow up here. Thanks for filing this issue!

HI just an update to this, I finally managed to catch the culprit, it took 3 runs and on the 3rd I just got lucky and it decided to actually tel lme what the error was. It was due to not having MPV (https://mpv.io/) installed. I'm developing this on a Windows (Regretting not using my mac now) with hope to move this to a Linux based OS in the near future.

It seems ElevenLabs might be using MPV under the hood for the stream() method. After installing MPV and updating my PATH I managed to get this working.

That's right, awesome!
