we planning use cobalt port on our embedded platform run applications amazon prime along youtube. possible use applications other youtube? if so, expected run-time footprint of cobalt? also, there licensing cost associated cobalt? cobalt can run application has been engineered run within cobalt subset of html/css/webapi. unlikely amazon prime video run out of box on cobalt, made run effort. cobalt open source, , has no licensing fee. for youtube, cobalt takes 130mb of cpu memory. gpu usage depends lot on image cache settings , ui resolution. the binary 5mb stripped , compressed, 19mb uncompressed. our icu data 2mb compressed, 6mb uncompressed. have couple different font options take varying amounts of space. can cover in 10mb of uncompressed fonts. these numbers subject significant change.
