All but two of the videos are broken for me on both Chrome and Firefox. I would love to see the rest!

I encourage people to read the original Propagator Networks paper by Alexey Radul (advisor: Prof. Gerald Sussman of SICP) referenced in the Prior Work section. It's full of fascinating ideas.

As a workaround in firefox, I was able to right-click, "save video as", and open in VLC.


Would love to know which videos are broken and any other details so I can try and fix that!


Firefox doesn't support H.265/HEVC.

bridging.mov and examples.mp4 are working as they are H.264/AVC, the other videos are H.265/HEVC


None of the videos played for me in Safari 16. =(


None of the MP4 videos play in Firefox. The MOV videos play fine.

All the videos play in Safari. I have not tried Chrome.


good to know! seems that I'm using encodings for those which Firefox does not support https://stackoverflow.com/questions/73855321/why-wont-mp4-vi...


The same thing seems to apply for Zoom background videos.


Yeah I can't see most of the videos, either. :(

I absolutely love Alexey Radul's dissertation. So interesting to see this article show up on the HN front page after I just published my own experiment with propagators yesterday: https://dthompson.us/posts/functional-reactive-user-interfac...

I need to learn more about the design decisions behind scoped propagators and why they deviate from "regular" propagators.
