I’m running headless Chromium with Puppeteer in my Azure Web App Service’s container:
const browser = await puppeteer.launch({
headless: true,
executablePath: await this.browserDownloader.getPath(),
handleSIGINT: false,
args: [
'--no-sandbox',
'--disable-setuid-sandbox',
'--disable-web-security',
'--disable-site-isolation-trials',
'--user-data-dir=.',
'--use-gl=egl',
'--enable-features=sharedarraybuffer',
'--enable-features=VaapiVideoDecoder',
],
});
Here are the details obtained by running lscpu through SSH in my Azure Web App Service:

As far as I know, Azure Web App Service containers don’t have GPUs. Right?
I’m using Chromium to open my basic React app, which uses Zoom’s Web SDK to extract video streams from meetings. It works as expected!
However, when streams are started and being extracted, Zoom’s Web SDK is giving me the following logs:
> VP9?: false AMD?: false AMDdecodecheck: true isenbaleHD:true enable720p?: false capacityfor720: false
> Can't subscribe to 720p video stream, will downgrade to 360p stream
I suspect this is because my machine and the Chromium running on it don’t support the VP9 codec.
I also think that hardware-accelerated video decoding might be needed for higher resolution streams, but I’m not sure.
My question is:
Is it possible to enable hardware acceleration (and/or the VP9 codec) in Chromium on a machine with no GPU running an AMD EPYC 7763 CPU on Linux?
If not, are there alternative ways to simulate hardware acceleration or VP9 in a browser running on Linux?
Are there any configurations, command-line flags, or software decoding options in Chromium that I can use to achieve this?
Any insights or suggestions would be greatly appreciated.
What I’ve tried:
I tried running the code locally in Google Chrome on my Windows machine with an AMD Ryzen 5 3600 6-Core Processor CPU and an NVIDIA GTX GeForce 1660 Ti GPU. I received the following log from Zoom’s Web SDK:
VP9?: true AMD?: false AMDdecodecheck: true isenbaleHD:true enable720p?: true capacityfor720: true
No downgrading happened, and the stream was perfectly extracted in 720p!
I checked chrome://gpu/ and saw this:
