locmaf.dev

LOCMAF is specified in the IETF Internet-Draft draft-einarsson-moq-locmaf. The editor's copy is at https://eyevinn.github.io/locmaf-id/ and the source repository is Eyevinn/locmaf-id.

npm run build:slides:pptx Slide deck → public/slides/locmaf.pptx

Style

Theme follows the Eyevinn Technology brand (see ../../ev-marp/ for the upstream PowerPoint-aligned MARP theme):

  • LevelOne brand font, dark gradient background
  • Orange #FC9900 for primary accent (CMAF chunks, headings)
  • Cyan #61B5E5 for secondary accent (LOCMAF deltas, links)
  • White on dark for body text

The LOCMAF logo visualises the format itself: a sequence of full CMAF chunks, compressed into tiny delta blocks for the wire, then reconstructed back into identical CMAF chunks at the receiver.
