HTML5 Play Movie From Multiple Parts Without Flashing Screen

I have a video tag and a movie cutted in parts of 10 seconds each, with name: 1.webm, 2.webm ....... 1535.webm. I tried to make a js code which find when the video is ended and pla

Solution 1:

It becomes very difficult if you are changing the src of the video as it will load the entire video once src changes and hence you are facing flashing screen effect. It seems impossible to get seamless video by using video parts yet you can try it this way:

Pre-load all the videos using different elements for each video and set preload="auto" attribute to all the elements. You need to play with the visibility of the elements in such a way that you will play one video at a time. First video will be autoplayed. As the ended event fires, just change the visibility of the next element to be true and previous element to be false(Do not use dispay:block/display:none as I have observed that in some mobile devices, video tags having style display:none are not being pre-loaded by browser). Also maintain some background to the video just to avoid white background flash effect.

Refer this snippet:

var my_video = document.getElementById("my_video");
var my_video2 = document.getElementById("my_video2");
document.querySelector("#my_video").addEventListener("ended", nextVideo, false);

function nextVideo() {
  my_video2.play();
  my_video2.setAttribute('class', '');
  my_video.setAttribute('class', 'hidden');
}

.hidden {
  position: absolute;
  top: -10000px;
  left: -10000px;
}
video {
  background: black;
}

<video id="my_video" width="640" height="480" preload="auto" autoplay controls>
  <source src="test.mp4" type="video/mp4">
</video>
<video id="my_video2" width="640" height="480" preload="auto" controls class="hidden">
  <source src="test2.mp4" type="video/mp4">
</video>
<button type="button" onclick="nextVideo()">Next</button>

Solution 2:

May be this will help you we make two video tags and set first 10 sec movie on first video tag, second movie on second video tag and third on again first video tag this process done one by one.

check my link http://jsfiddle.net/qoch687a/2/

There is timeupdate event which triggers every sec and we check duration

video.ontimeupdate = function timeUp(e){

    if(parseInt(e.originalTarget.duration - e.originalTarget.currentTime)==1){
        document.getElementById("my_video1").src=videos[1];
        document.getElementById("my_video1").play();
        document.getElementById("my_video1").onloadeddata = function(){
            clearInterval('intTime');
            intTime = setTimeout(function(){document.getElementById("my_video").style.display="none";
            document.getElementById("my_video1").style.display="block";},1000);

        };
    }

}
