javascript - Local HTML5 video playback with MP4/WebM Blob chunks -

-

i'm looking way play relatively large (up 500mb) mp4/webm means of html5 video. complication video isn't available url or file sequence of blobs.

the app oriented @ desktop (chrome) , mobile (android/ios webview) offline usage. there's no ability stream video locally, i'm counting entirely on client-side js (no native platform extensions).

the video stored in resource container (storage implementation out of scope of question) , can't loaded @ once because of size, can retrieved , buffered several blob chunks.

it more convenient read chunks unparted mp4/webm instead of splitting it, guess approach requires local streaming server.

it possible split video smaller clips (~10mb) beforehand if necessary, should played seamlessly.

an approach i've tried looks that

var player = document.queryselector('video');  getblob('webm-chunk1') .then(function (chunk1) {   var url = url.createobjecturl(chunk1);    player.src = url;   player.play();    return getblob('webm-chunk2'); }) .then(function (chunk2) {   var url = url.createobjecturl(chunk2);     player.addeventlistener('ended', handler, false);    function handler() {     player.removeeventlistener('ended', handler);      player.src = url;     player.load();     player.play();   } });

here a plunker demonstrates it, works in chrome. there problem seamless playback, gap between 2 chunks noticeable. if there 2 <video> switched on ended event, ~100ms gap still there.

how can sequence of progressively loading blobs played seamless html5 video?
