To clarify a number of points: - Chrome (and other browsers) support MPEG-DASH via javascript through the Media Source Extensions (MSE) (which Safari actually supports[1]) - Firefox does not "bundle" H.264 (because of licensing) but has recently supported it where the OS provides it[2]. - HLS and MPEG-DASH are fairly similar in theory, but in practice HLS requires complete (with header/metadata) chunks whereas MPEG-DASH can "arbitrarily" chunk a video file and just feed into a MSE video stream. Both work with manifest files detailing different resolutions/qualities and chunk sizes + offsets.
