M4S at a glance
M4S
CMAF emerged from industry convergence between Apple's fMP4 HLS initiative and DASH-IF fragmented MP4 requirements, producing a common segment format that both ecosystems could serve from a single encode.
Xfig at a glance
Xfig
Xfig began in 1985 and accumulated decades of maintenance and export tooling, which made the .fig format a durable bridge between interactive diagram editing on Unix systems and downstream conversion to PostScript, PDF, and other outputs.
