Using the HTML5 <video> tag, the video plays when the image is clicked in iOS 7 and below, but in iOS 8.1 it plays when the app starts -

i implementing video feature in application using html5 <video> tag. want video play when image clicked. it's working in versions ios 7, in ios 8.1, video starts playing automatically after app initialization

i implemented following way:

<div style="margin-top:40px;">   <img src="images/play-video-screen.jpg" onclick="video()" value="loading video...." />        </div> <div>     <video controls autoplay="true" id="welcomevideo" src="video.mp4" style="display:none;width:2px">         <source type="video/mp4" >    </video> </div> <script>     function video() {         document.getelementbyid('welcomevideo').style.display="block";                var videoel = document.getelementsbytagname('video')[0];         var sourceel = videoel.getelementsbytagname('source')[0];         sourceel.src = 'video.mp4';         videoel.load();     } </script>

if remove autoplay="true", video doesn't play @ all, when image clicked.

as matt gibson wrote, may want brush on html video , audio. places start:

mozilla developer network - using html5 audio , video

safari developer library - ios specific considerations

(my rep isn't high enough post more 2 links, google search "html video tag" more.)

as code: there few things going on here want change work properly. of these not necessary working, more style advice.

starting @ top:

  1. set id image file container.
  2. set explicit width , height values (based on video file's dimensions) video container. (these can set in js using videoel.setattribute("width","___px") , videoel.setattribute("height","___px") if size variable video video.)
  3. remove autoplay property , width style declaration.
  4. set variables in js each of elements you're touching; image container, video, , source elements. -- note i've called var once in function. video element 1 "need" for, calling other elements once each, find practice define them in own variables, in case decide manipulate of these elements later. also, getelementbyid 1 of fastest methods can use grab elements dom, use when can.
  5. .load() video did, .play() it.

your code should resemble following:

<div id="videoimg" style="margin-top:40px;">     <img src="images/play-video-screen.jpg" onclick="video()" value="loading video...." /> </div> <div>     <video width="620" height="465" controls id="welcomevideo" style="display:none;">         <source id="video1" type="video/mp4">     </video> </div> <script>     function video() {         var videoel = document.getelementbyid('welcomevideo'),             sourceel = document.getelementbyid('video1'),             videoimg = document.getelementbyid('videoimg');         videoimg.style.display="none";         videoel.style.display="block";         sourceel.src = 'video.mp4';         videoel.load();         videoel.play();     } </script>

tested on ipad(3) running ios7.1.2. should work in ios8 fine.
