February 20, 2026

Watch this episode again on YouTube.

  • Dan used BirdNET and rtsps streams to turn Loud Birds In Your Local Neighborhood into numbers...

    • ... and post them to Bluesky at

  • Eli appears as a challenger from Stream.place and talks to us about bringing video to Content-Addressed Specs, and DASL to the Atmosphere

    • ... and totally does not tease us about video on demand (VOD) on Stream.place

    • Also, C2PA for media, for verifying content authenticity and establishing provenance chains -- that some news organizations, like BBC Labs, are experimenting with

    • and there's the S2PA -- the simple standard for provenance and authenticity -- which is a fork of C2PA, because maybe the goals/needs of decentralized social media are aligned with Adobe's C2PA which came from the top-down root cert provider x.509 model, versus a lets-encrypt bottom-up model that's much more in line with our ATproto world

    • and Jess Wetherhead talked about the problems with C2PA on The Verge in Reality is Losing the Deepfake War.

    • ... and this is in conjunction with !

      Like ATProto has content provenance and content signing. But there this hasn't extended into video. I'm really excite to hear that @stream.place is riffing on this and building some specs to provide video signing w/ ATproto identity.

    • Eli's super excited to hopefully have this launched by the time of ATmosphere Conference in March!

    • Everyone using Stream.place is using one big-ass server that Eli's running, but the whole thing has been designed from the start to be able to self-host

    • ... it looks like we might get a contemporary version of something like SMIL:

      • Doing it together

      • We're going to talk about Permissioned and Private Data!

        • Rudy announced private data/posts that will only show up to people in Blacksky. The data for those posts is held in Blacksky application database.
