We recommend using VideoJS as your HTML5 video player because it has extensive functionality and a plugin system.

VideoJS plugins

Example

https://github.com/spodlecki/videojs-event-tracking#positioning
Track Overall Percentile (1st, 2nd, 3rd, and 4th) of Completion. This event triggers each quarter of a video.

player.on('tracking:first-quarter', (e, data) => {
    logVideoEvent(e.type, data, 25);
});
player.on('tracking:second-quarter', (e, data) => {
    logVideoEvent(e.type, data, 50);
});
player.on('tracking:third-quarter', (e, data) => {
    logVideoEvent(e.type, data, 75);
});
player.on('tracking:fourth-quarter', (e, data) => {
    logVideoEvent(e.type, data, 100);
});

function logVideoEvent(eventName, eventData, progress) {
    const mult = 1000000; // turn seconds into microseconds to get rid of decimals
    eventData.meta = {
        progress: progress,
        currentTime: this.player.currentTime() * mult,
        duration: this.player.duration() * mult,
    };
    console.log(eventName, eventData.meta);
    mobilelocker.logEvent('Video', e.type, action, eventData);
}
