  • Stream a USB webcam to HDMI on a Raspberry Pi

    This post exists to collect my notes on displaying a USB webcam on the Raspberry Pi HDMI outputs. This is not the same as streaming the webcam (easy), and this is not for use with the Raspberry Pi camera module. This is specifically for USB UVC webcams.

  • How to make an RTMP Streaming Server and Player with a Raspberry Pi

    In this tutorial we'll use a Raspberry Pi to build an RTMP server that plays out any video stream it receives over the Raspberry Pi's HDMI port automatically. This effectively turns a Raspberry Pi into a Blackmagic Streaming Bridge.

  • The Real Cause of the Sign In with Apple Zero-Day

    The zero-day bug in Sign In with Apple actually had nothing to do with the OAuth or OpenID Connect part of the Sign In with Apple exchange, and very little to do even with JWTs. Let's take a closer look to see what actually happened.

  • Meetable: Updates for Virtual Events

    Meetable is the software that runs events.indieweb.org and a couple other event sites that I host. Over the last couple months, we've had to cancel a bunch of IndieWeb events or convert them to virtual events, and I've been watching for patterns to see if there was anything the software could do to facilitate this.

  • Making Meetable Easier to Install

    I've been working towards making Meetable more useful to others by making it easier to configure and deploy. I took a few shortcuts during the initial development that let me finish it faster, primarily by offloading authentication and image resizing to external services. While that's great for me, it means it requires setting up two additional projects if someone else wanted to get it running.

Hi, I'm Aaron Parecki, co-founder of IndieWebCamp. I maintain oauth.net, write and consult about OAuth, and am the editor of several W3C specifications. I help people learn about video production and livestreaming and dabble in product design.

I've been tracking my location since 2008 and I wrote 100 songs in 100 days. I've spoken at conferences around the world about owning your data, OAuth, quantified self, and explained why R is a vowel. Read more.
