HTTP Archive suggests that only 1% of mobile pages (tested) are using video, but video’s contribution to the average mobile page size is now over 5% (up from negligible 18 months ago).
What should developers / web owners be doing to reduce the impact of video on a) mobile page size and b) mobile page performance?
Are there any guidelines, standards and/or tools to help keep developers / web owners on the straight and narrow?
For example, are there certain bitrates appropriate for mobile device / mobile network v mobile device / WIFI? And should sites detect device / connection and serve up the appropriate video at the right bitrate?
I am researching/writing an article for ClickZ on this subject.
