I ran into the same issue, and it took me hours to figure out what the issue was.

Thanks to this page I simply added another argument '--no-sandbox' next to '--disable-dev-shm-usage'.

So, if anyone is like me...and has no idea what to do. I went into destreamer.ts, and scrolled down to the section between lines 47-52 (where it says "async function rentVideoForLater.....". From here, you simply add the argument I mentioned above.

async function rentVideoForLater() {
    console.log('Launching headless Chrome to perform the OpenID Connect dance...');
    const browser = await puppeteer.launch({
        // Switch to false if you need to login interactively
        headless: false,
        args: ['--disable-dev-shm-usage','--no-sandbox'],;
    });
    const page = await browser.newPage();
    console.log('Navigating to STS login page...');

Thank you so much for creating this...I just downloaded my first video from Stream, and it works perfectly. Beautiful job.

Really happy you tracked this down and it now works for you. We should probably make --no-sandbox the default given the security concern it bring it's not really something to worry about for our use case. Let me try to run this with --no-sandbox on both Mac and Windows and if all goes well i'll make it the default.

On windows, after adding this flag and building it again, the error/warning is still displayed but does not terminate running. Is this expected? I don't think the download is progressing. I can see the sandbox change reflect in the transpiled file as well.

It opens Chromium and it's impossible to download the video. How to solve this issue?

@AndreaLonghitano Can you provide the logs please?

Closing due to inactivity, please try out the new code (git pull and build), we improved a lot of the logic.
