Info-beamer hosted OS 14 release thread

Updated to 240515-125a8c:

  • Allow YUVJ420P and YUVJ422P video frame format.
  • Added a way to remotely show a small text overlay on demand. Could be used for another ‘second factor’ auth in the future or as a way to recover account access. This isn’t used yet.

Known issues:

  • The PoE issue from above
  • There’s still sometimes an annoying flickering of the last two frames when info-beamer is briefly stopped while switching setups. I’m not sure why that happens as nothing info-beamer is doing should cause that. It seems almost as if double buffering swaps between buffers while DRM/KMS is shut down. Odd.
