Someone said earlier HTML5 is actually not widely viewable though so maybe i have one of the few browser brands that happens to support it (Firefox)?
Firefox supports HTML video using Ogg Theora and WebM video formats. I was one of the developers that implemented the support for those formats in Firefox. Firefox also supports H.264 on some Android Devices, Windows desktop in some builds and on Firefox OS devices. Linux support for H.264 is coming soon via GStreamer.
