flash - How does youtube player work -

-

what i'm interested in video quality.

do convert each video file many separate video files, or convert file on fly when user watching video preserve space? how different video qualities made.

also, video formats works flash? 1 commonly used?

what sacrifice if use html5 instead of flash? saw youtube switching html5, player work in every browser, ie7?

how hard make youtube flash or html5 player copy?

thanks.

every video uploaded converted couple different mime types. html5 allows add videos without needing own custom flash player. can make own player using normal elements found in every browser. although html5 not supported in browsers, it's becoming more popular , (hopefully) implemented in browsers soon. i'm not sure video formats work flash, can assume do. make replica of html5 youtube player in day.

mime types - mime types different file types. different files. example, have mp3 file, convert wav file , ogg file , have 3 different mime types. read more info on mime types
