Get thumbnails preview on the Videojs player's time line out of the box with this state of art plugin that extracts key frames from H264 mp4 on the fly and displays them as still images, so that you do not have to pre generate and store them separately. To generate the thumbnails plugin uses byte-range http requests so your mp4s must be accessible via http. The key frames occur naturally when there is a big change in the scene, however you can user settings during the encoding process to increase the frequency of their appearance. The plugin is part of the series of state of art plugins by Easy-Bits.com based on http multistreaming and javascript mp4 parsing.
