Create a video hit counter like youtube.

Create a "view hit counter" like youtube, where, when a user views the video, the counter increments. But it should not increase the counter at every refresh. Mechanisms to ensure fair hits should be ensured. For example, if the user is viewing the video, 1. the counter should only increase after he has watched around 2 mins(or a duration specified by me) of the video 2. If the user refreshes the page before a specified time, the hit counter doesn't increment. So I guess, you will have to take into account his session. 3. Since there will be many videos in the website, for each video each user should have separate session, otherwise what will happen is that even if the user is viewing another video, the counter won't increase. 4. The different videos should be identified by different ids. 5. This script should work across all devices like desktops,laptops,android, ios etc. The videos will be played in the standard html5 video tags
