Studying different ways to serve video to study the performance aspects of video delivery. Let's begin by modifying both the bitrate and the width of the video.
To do this, use the indexparam.html, and add width and br parameters to the url:
indexparam.html?width=960&br=1000 will give bitrate 1MBPS and width of 960.
The base video is a 38s clip of Big Buck Bunny.
38s, 98.1MB, 20.5 MBPS, mov,mp4,m4a,3gp,3g2,mj2
We can now run tests for this video at varying bitrates and widths with webpagetest to see how they load.
What I see is that above 1920 - test fail on the G4. above 1900, test fail on the Alcatel 1x. This is a GPU limitation on how big a file these devices can process.
