Issue with offthreadvideo extracting frames on lambda with preflight request differences.

[JonnyBurger]

From message posted on Discord by jonnyburger

hmm, thanks for posting!
that seems problematic actually, something that might have gone under my radar and might have just surfaced it

offthreadvideo should not try to extract frames when there is a preflight request
normally there is no preflight request except when the domains differ

but I just realized that on lambda this is different
the website is hosted on S3 but the asset is proxied through localhost

I'll file that! currently I am a bit slower because I am going to react conf but I'm trying to get it this fixed in a new update soon

did you delete the original message? I cannot read it anymore 🤔

In my situation, sometimes the video gets generated but sometimes it doesn't. My guess is the RAM usage.

IDK if this helps but these are my below configs -

Please note that we didn't face this situation in lambda, but it happens in a ubuntu pm2 server, we are trying to have an instance of g4dn.xlarge, with 6GB ram within the pm2 (reserving the remaining RAM for basic operations like ls

We'll still investigate the issue until the end, but I am closing the issue because OffthreadVideo doesn't have the problem as described in the title.

OffthreadVideo does reply to preflight requests correctly (if there are any) and immediately.

This issue is just the same as https://remotion-git-delay-render-proxy-docs-remotion.vercel.app/docs/troubleshooting/delay-render-proxy
