Hi this is Tim. I made this website. It's currently running on a $5 droplet on DigitalOcean so conversions will take a while. I'm testing out the waters here on HN to see if there's anyone interested in it. Please let me know if you have any questions regarding it.

Edit: I haven't chosen I license for this yet, sorry.

Why are you transcoding all the time? You could probably save your little droplet a bit of heartache by using ffprobe to check if the video is already h264 (or h265)+aac and just do -c copy in that case.

That's a great suggestion. I'll add that to my list of todos!

Did you look into using something like ffmpeg.js to do the heavy lifting client-side? Note I have no idea if ffmpeg.js supports all the features you need (ie HLS).

I didn't even know that existed, but now I will definitely take a look! Thanks for the feedback!

What did you end up using for queueing conversion jobs?

Fantastic question. I'm not even doing that yet. How embarrassing!

Right now I'm just spawning sub processes like crazy and hope they don't overwhelm my machine. In the future, I plan to use a queue and also to monetize on API queries.

I haven't looked into queues in Javascript yet. If you have recommendations, that be appreciated :)

This is really just an MVP to see how the internet crowd reacts to it. I'm glad it does in a positive way :)

Haven't used it, but "bull" shows transcoding as their example, so I assume they've run through your use case: https://github.com/OptimalBits/bull

Don't use bull, use NATS[1] - happy with it so far with the Node SDK.

[1] https://nats.io

That seems more messaging oriented than job oriented. Does it manage job concurrency limits, time outs, etc?

Why do you say not to use bull? I've been quite happy with bull in our production environments so far.

RabbitMQ is what we use at work or sns for messages to lambdas.

I think you're experiencing the Slashdot effect.
