html5-video

问题 I am attempting to play an HTML5 video within my WebView app. It works as expected on every device I have tested that is running Android 5.x, but does not work on any device running 4.x , meaning it essentially doesn't work at all. I have turned on hardware acceleration and I have set a WebChromeClient as the docs say to do, but the video still will not play. In order to support inline HTML5 video in your application, you need to have hardware acceleration turned on, and set a WebChromeClient

问题 I am programming an interactive video (kind of game) where the user make actions on a side panel and actions happens in the video. For a part, the video is waiting for user action on the panel, so it has to loop until the action has been launch by the user. So at 15 seconds, I get back to 11 seconds as long as the user has not made the action, video is designed to be a perfect loop. My loop is working, but the problem is thats it's not seamless. At 15 seconds, it stops for like a second, and

问题 Is there a good way to delete a single TextTrack added via JavaScript to a HTML5 <video> tag? The following code is a simple demo of how to add a track, but I haven't found a good way to remove one: document.querySelector('video#myVideo').addTextTrack(...); 回答1: There is no mechanism to remove an added text-track (probably a flaw (?) in the current specification. There is also an onremovetrack event but...). The only thing we can do is to disable or hide it. Make sure you keep a reference to

问题 So I have a <video> element that has its video in a <source> element found in the <video> element. I can press some buttons (each one has a data url to a local video) and these videos get loaded into the <source> element's src value. My <video> has attributes loop and muted (no controls attribute). I also have a custom play button that I target using jQuery, and use that to play the video. This solution works fine on desktop. However, I keep getting this error: Failed to execute 'play' on

问题 I want to know if it's possible to play a video when you click on an element of an image, and play another video if you click on another element of the same image ? For instance, imagine a picture of a room : - if I click on the area where the TV set is, the image disappears and video1 starts. - if I click on the chair, same thing but video2 starts instead. Is this possible using HTML5 and Javascript? If so, how am I going to do that ? Thanks a lot for reading ! 回答1: Yes, it is possible. I'm

问题 I have designed an i-phone-like screen on a web browser where I am testing this application I am in the process of building. It works great up until the point where I want to call out another set of videos. What works The application is structured so that when the user sees the screen she is directed to a channel that has a vertical video. The buttons on the top left and top right advance to the next and the previous video. <div id="topVid" class="videoContainer"> <div class=

问题 I embed a mp4 video into a webpage, using the embed src script. I can view it when I browse from iphone, but not android. I did some research and found out that I need to use html 5, which uses the tag. However, how do I find out what version of the video I have? I tried <video width="560" height="340" controls> <source src="<?php echo $video; ?>" type='video/mp4; codecs="avc1.42E01E, mp4a.40.2"'> </video> But it's not working either. Any ideas? Thank you in advance 回答1: <video id="video"

问题 I am a newbie to html5 and i was trying to include a UDP stream(UDPaddress:port) within the video tag. Is this possible. If so how can we do this? 回答1: Short answer: No, browsers generally don't support UDP. Long answer: The chapter on the video element in the standards states that the src attribute must contain valid non-empty URL potentially surrounded by spaces, which in effect means that it must contain an URI or IRI. While there is nothing in these specs that say UDP is unsupported (page

问题 I have to develop an html5 application that runs on all major browsers (Chrome, Firefox, IE9, Safari and Opera) and one of the things requested was for it to be able to play videos as well.
