Get frame numbers in HTML5 Video

Question

I am trying to capture each frame number of the video however it looks like there is no way of achieving it. So I started my own clock to match the frame numbers of the video but they never match and the difference keeps increasing as the video progress.

Please have a look at my bin. http://jsbin.com/dopuvo/4/edit

I have added the frame number to each frame of the video from Adobe After Effect so I have more accurate information of the difference. The Video is running at 29.97fps and the requestAnimationFrame is also set to increase the number at the same rate, however I am not sure where this difference is coming from.

Sometimes they match and sometimes they don't. I also tried doing it offline but I get the same results. Any help.

Answer 1

I found something on github for this. https://github.com/allensarkisyan/VideoFrame

I have implemented it in this fiddle: https://jsfiddle.net/k0y8tp2v/

var currentFrame = $('#currentFrame');
var video = VideoFrame({
    id : 'video',
    frameRate: 25,
    callback : function(frame) {
        currentFrame.html(frame);
    }
});

$('#play-pause').click(function(){
    if(video.video.paused){
        video.video.play();
        video.listen('frame');
        $(this).html('Pause');
    }else{
        video.video.pause();
        video.stopListen();
        $(this).html('Play');
    }
});

EDIT: updated fiddle to new video so it works again.

EDIT: As pointed out, the video is 25fps, so I updated it, and while I was there removed reliance on jQuery.
Non jQuery version:
https://jsfiddle.net/k0y8tp2v/1/

var currentFrame = document.getElementById('currentFrame');
var video = VideoFrame({
    id : 'video',
    frameRate: 25,
    callback : function(frame) {
        currentFrame.innerHTML = frame ;
    }
});

document.getElementById('play-pause').addEventListener('click', function(e){
    if(video.video.paused){
        video.video.play();
        video.listen('frame');
        e.target.innerHTML = 'Pause';
    }else{
        video.video.pause();
        video.stopListen();
        e.target.innerHTML = 'Play';
    }
});
