So, I'm building a website on which users can upload an watch videos.
I'm using the standard HTML5 video player (<video...> <src>...
)
Currently, I use multiple sources: MP4, OGG and WEBM, for cross-browser compatibility
Due to the fact that maintaining three formats is both CPU intensive (converting) as well as eating away precious disk space, I started searching the need to find out whether it's really needed to support this three formats
According to the chart I found on Wikipedia (http://en.wikipedia.org/wiki/HTML5_video), OGG and MP4 should be sufficient, as all browsers seem to be supporting at least one of these formats
... or am I missing something?
For a comprehensive answer see: http://diveintohtml5.info/video.html There's a compatibility matrix toward the bottom that is beginning to be outdated, but was authoritative at the time the article was written.
