Stream Video or Screenshots to Jpg

take screenshots
       save to jpg
             make big composite jpg of several frames (strip)
               
update strip in browser
       scroll visible (change display dimensions with JS/css)

Each frame has a timestamp, from which the display range is computed, and the browser and server are synced

Each strip corresponds to 1 sec, or a period of time which matches the network transfer rate

During playback, jpg size is altered to match playback and transfer rates, though resolution may suffer, motion is smoothest

Keep pace with
(a) buffer
(b) transfer time
(c) screenshot production (available on server)
