html5-video

问题 I use the following code to change a videos src attribute after video ended. I preload the second video I change the src to link to the second video. In IE and Firefox this works perfectly but in Chome 27.X.X the video element seems dead after changing the src . Strange thing is... if I use a breakpoint to step through the code in my .ended function it works fine! HTML <video id="vid1" preload="auto" width="640" height="480" src="/Trans/video/sleigh60.mp4" controls> </video> <div style=

问题 I want to include a recorded video (saved as a blob) to a form that will be posted. Two questions: What is the input type required to post the blob? How do I assign the blob to that input type? Some of what I've seen suggested using a input type of file. Example form: <form method="POST> <input type="text" class="hidden" name="filename"/> <input type="<UNKNOWN>" class="hidden" name="filedata"/> <input type="submit" /> </form> I'm assuming I'd do something like $("[name=filename]").val(myBlob)

问题 I'm trying to implement HTML5 Video in a site and for that I'm using VideoJS, so far it works great in Firefox and Chrome but my problem comes when I try to play the video with IE9. The player would load and when I click on the Play button, the loading image would appear and it would get stuck without doing anything. I've checked other websites and they suggest that the MIME Type that the server is sending is wrong but I've checked already that and it's not the case. Any ideas? 回答1: Have you

问题 Does Firefox 8 (win/64) Support mp4? I cannot find any mention on MDN of support for mp4 AND it's not playing mp4 files locally on server. Please advise. sleeper 回答1: Firefox does not support the mp3/mp4 technologies, as aspects of them are licensed. See the 'official' support list for Firefox here: https://developer.mozilla.org/En/Media_formats_supported_by_the_audio_and_video_elements More about why Firefox avoids it: http://en.wikipedia.org/wiki/MP3#Licensing_and_patent_issues 来源： https:/

问题 In the HTML5 spec, it suggests you put fallback material in the <video> tag for older browsers that do not support it. <video width="400" controls> <source src="mov_bbb.mp4" type="video/mp4"> <source src="mov_bbb.ogg" type="video/ogg"> Your browser does not support HTML5 video. </video> However, I cannot find anything for fallbacks when all source types are unsupported. For instance, my Chromium browser cannot play video/mp4 , but it can play video/ogg . So I would expect this to render the

问题 When viewing my web page in Firefox 31 on windows 7, the video tag shows a picture of the video first frame with dark/gray overlay. The video works with no problem. I'd like it to show without this gray/dark color on it (the color goes away once the video is played). When viewing the same page on Chrome 36 or IE , the image is white and there is no gray color on it. Here is screen shot of the same page to illustrate The HTML code uses is <video width="300" height="240" controls> <source src=

问题 I'm trying to determine whether the browser supports autoplay on load. I'm using the following code, and it works fine on Android chrome, but for Desktop Chrome none of the lines in .catch or .then get executed. The promise seems to just return Pending promises ad infinitum. Is this an actual Chrome bug or am I not understanding how Promises work here? const promise = document.createElement('video').play(); if (promise instanceof Promise) { promise.catch((error) => { // Check if it is the

问题 I was trying to capture a frame from video and drawing it in canvas using HTML5, but the below code is not working. when i click on the start button the canvas is filled with black color <video src="video2.mp4" autoplay="true" type="video/mp4" width="300" height="200" id="vid"> </video> <canvas id="cvs"> </canvas> <button onclick="start()">Start</button> <script> var video=document.getElementById("vid"); var cvs=document.getElementById("cvs"); function start(){ cvs.getContext("2d").drawImage

问题 I'm using getUserMedia() , and when implementing constraints (see below) they only work in Chrome and not Mozilla. The size in mozilla always appears stretched and ends up bigger than the one in chome. var vid_constraints = { mandatory: { maxHeight: 180, maxWidth: 320 } } var constraints = { audio: false, video: vid_constraints }; navigator.getUserMedia(constraints, successCallback, errorCallback); After reading some, it appears that MozGetUserMedia() doesn't support resolution constraints.

问题 I am building a phonegap application where i need to use video and audio streaming feature, i found that mediaelementjs seems more suitable for cross platform video and audio feature. I created one demo and its working fine on iOS & Android browsers, but when i prepared phonegap build its not playing video or audio on android device. Is mediaelement.js compatible with phonegap?if no then is there any other video\audio player plugin available which can use with phonegap, instead of using
