Webm HTML5 doesn't seem to be compatable with IOS safari -

-

i'm struggling understand why wouldn't supported. snippet follows: 

<video autobuffer="autobuffer" autoplay="autoplay" class="maskfill" loop="loop" src="/videos/maskfill.webm" type="video/webm; codecs=vp8,vorbis"></video>

is there official reason this? or there recommended alternative? i've considered moving them on mp4 i'm doubtful of lack of compression.

the answer simple: it not supported. reason ios can hardware decoding of few codecs (typically h.264 profiles).

so, recommended alternative use h.264.
