M4S w skrocie
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.
HEIC w skrocie
HEIC
HEIC became widely recognized when Apple adopted HEIF-based image storage in its consumer ecosystem, turning a standards-driven container family into an everyday format users actually encountered.
