Script to monitor live streams and send an Amazon SNS if the stream is down (and possibly take restorative action)

Future:
 Black detect: ffmpeg -i out.mp4 -vf blackdetect -f null -
 Note the following doesn't seem to fully work without looking at the debug logs
 On live ffmpeg -y -i rtmp://cp30129.live.edgefcs.net/live/videoops-videoops@50541 -vf blackdetect -t 10 -loglevel debug -f null -

How to setup a practically free CDN

I've been using [Backblaze][bbz] for a while now as my online backup service. I have used a few others in the past. None were particularly satisfactory until Backblaze came along.

It was - still is - keenly priced at a flat $5 (£4) per month for unlimited backup (I've currently got just under half a terabyte backed-up). It has a fast, reliable client. The company itself is [transparent about their operations][trans] and [generous with their knowledge sharing][blog]. To me, this says they understand their customers well. I've never had reliability problems and everything about the outfit exudes a sense of simple, quick, solid quality. The service has even saved the day on a couple of occasions where I've lost files.

Safe to say, I'm a happy customer. If you're not already using Backblaze, [I highly recommend you do][recommend].

FWIW: I (@Rondy) am not the author of the content presented here, which is an outline from Edmond Lau's book. I've just copy-pasted it from somewhere and saved as a personal gist, before it got popular on newsnews.ycombinator.com. I don't remember where exactly the original source is from and neither could find the author's name, so I cannot give him/her the proper credits.
