问题 Hi I am trying to center the iframe for a Youtube video in Twitter Boostrap 3, currently it is left aligned. I have used the following html: <div class="embed-responsive embed-responsive-16by9"> <iframe class="embed-responsive-item" src="http://www.youtube.com/embed/zpOULjyy-n8?rel=0" align="center" id="videothumbnail"></iframe> </div> CSS: #videothumbnail{ height: 50%; width: 50%; float: center;} 回答1: Use classes col-xs-12 text-center .

问题 As the title says, I'm searching for cross-browser and mostly cross-platform solution for displaying html5 videos of different size resolutions . My main issue is that if a high resolution video is accessed from a standard/low definition device, it will not be played as the native video application can't handle it; this is mostly true on older/low-budget android devices, which have a standard or low display resolution. My best guess was to filter the video source file based on the device

问题 my HTML5 video autoplay is not working. <video preload="auto" autoplay="true" loop="loop" muted="muted" volume="0" id="myVideo"> I also tried without the ="true" value, and it doesn't work either.

问题 I have a video of a specified width and height, double clicking on which makes it go full screen using videoElement.webkitRequestFullScreen() . By default the video does not have any controls. But for some reason, on going full screen, the default controls pop up. Here is what I'm doing : <video id="videoId" width="320" height="240" autoplay="autoplay" ondblclick="enterFullScreen('videoId')" src="Blah.mp4"></video> And the enterFullScreen(...) function is defined as : function enterFullScreen

问题 On an Ionic project I am recording videos with cordova capture plugin which in fact is based on Apache media-capture plugin. Android users can choose video dimensions, but on iOS there are no buttons for that. I am testing with an iPhone 5 which records in 1920x1080, but with my Ionic app videos are 480x360, notice also aspect ratio is 4:3 no 16:9. I want at least a 720p video dimensions . I read plugin documentation and there are only three options; duration and limit. Does it means is not

问题 I have a mkv file. It's video codec is avc and audio codec is ac3. How can i put it into a html5 video tag? I use the <source src="01.mkv" type="video/x-matroska" codecs="a_ac3, avc"> but in safari 5 or chorome4 it doesn't works. 回答1: Your <source> tag is malformed. You need to put the codec information inside the value of the type attribute instead, eg: <source src="01.mkv" type='video/x-matroska; codecs="a_ac3, avc"'> The type attribute contains a full MIME specification, and codecs is an

问题 I am creating a Video Sniffing Framework where I have to sniff different browsers' HTML5 Video playing capability. For that I used the canPlayType() method which is giving me three possible results: the empty String (when unable to run the video) "maybe" "probably" I need to know the exact difference between "maybe" and "probably". Please let me to know if anyone can resolve my confusion. Thanks in advance. 回答1: probably means that the browser can play the media type described. maybe means

问题 I want to make a video call with webrtc. I have two streams, one is local and the second one is remote stream. In Chrome, I mute my video tag in order not to hear my voice which leads to echo. My HTML tag is like; <video style="position:absolute;right:5px;bottom:5px;display: inline;" class="localVideo" autoplay="autoplay" muted="true" src="mediastream:3ffffe01-da89-44d9-b9cf-454b11ec6a6a" height="25%" width="25%"></video> In Firefox muted="true" property not working, so that I hear my own

问题 I have Disable cache tick removed and still request is made on each video loop iteration(Only on chrome). What Initiator: Other mean in chrome inspector network section? First time the video is loaded from the host, but after that all requests are loaded from Other . Each iteration video size is the same, not (from cache) . Is that mean the browser download it every time? Can it be avoided somehow without saving the video in localStorage(I saw it in similar question), because this solution
