createSingleVideo() - Failed to launch the browser process #38

Open simon-online opened 1 month ago

I have a batch process that uses WVC to generate a whole lot of different videos on a Ubuntu 22.04.4 LTS server. Occasionally when I make the first call to createSingleVideo() I get the following errors and it hangs:

TROUBLESHOOTING: https://pptr.dev/troubleshooting

    at ChildProcess.onClose (file:///home/genie/generator/worker/node_modules/@puppeteer/browsers/lib/esm/launch.js:258:24)
    at ChildProcess.emit (node:events:529:35)
    at ChildProcess._handle.onexit (node:internal/child_process:292:12)

This keeps happening occasionally and stops the batch process from running. Otherwise everything runs fine if this error doesn't occur on the first call to createSingleVideo().

I have wrapped the call to createSingleVideo() in a try catch but it doesn't seem to catch this error or return from the function call. Is there some way I can catch this error and retry?

Any idea what might be causing it or what I can do to troubleshoot it?

This is running on node v18.20.4 and web-video-creator v0.0.34

Also this is the config that I'm using.

wvc.config({
  frameFormat: 'png',
  numBrowserMin: 10,
  numBrowserMax: 12,
  numPageMax: 1,
  mp4Encoder: VIDEO_ENCODER.CPU.H264
});

I'll try enabling a display device on the VM to see if that helps improve reliability.
