问题 Is it possible to get the audio from an mp4 or webm video element in HTML5? I'm trying to use https://github.com/corbanbrook/dsp.js to calculate FFTs for audio, however, I only have the mp4 and webm videos. 回答1: Not sure if this answers your question but you can run the audio of the video through the Web Audio API node graph. The code below can be demonstrated by changing the gain and filter parameters. I only tested this on Chrome. <!DOCTYPE html> <meta charset="UTF-8"> <title></title> <body

Does Android 2.1's Browser Support HTML 5 and What Video Format Does It Play?

痴心易碎 提交于 2019-12-03 03:03:18
The company I work for produces a lot of video and we want to target as many devices as possible, but the question came up of what does the Android do? I personally own an Android based phone running 2.1, but I can't seem to get the HTML 5 tag to work. Even when I can trigger the browser to playback the video it just throws a notification error that it can't. Are there guidelines to producing Android/HTML 5 compatible videos? Is it truly supported? dar The android 2.1 browser currently does not support the html5 video tag the way the iphone browser does. To get the android browser to play the

问题 I use Node.js to stream via Websocket a realtime webm video to a webpage which will play it in a tag.

问题 I need to create an app that can record video using a webcam or mobile camera (it needs to be cross platform). So far I have written a small proof of concept using webrtc getusermedia. It can record the video and playback but I am not sure how to get the file to upload back to the server. Here is a link to this sample http://jsfiddle.net/3FfUP/ And the javascript code: (function ($) { window.URL = window.URL || window.webkitURL; navigator.getUserMedia = navigator.getUserMedia || navigator

.mp4 file not playing in chrome

I want to show a video on my website. I have created a .mp4 file and using the HTML5 video tag to add it to the html. The problem is that it is not being displayed in chrome. I would also like to know how I can replay it again and again. Romualds Cirsis After running into the same issue - here're some of my thoughts: due to Chrome removing support for h264, on some machines, mp4 videos encoded with it will either not work (throwing an Parser error when viewing under Firebug/Network tab - consistent with issue submitted here), or crash the browser, depending upon the encoding settings it isn't

问题 I've got a local video file (an .avi, but could be converted) that I would like to show a client (ie it is private and can't be published to the web), but I can't figure out how to play it in IPython notebook. After a little Googling it seems that maybe the HTML5 video tag is the way to go, but I don't know any html and can't get it to play. Any thoughts on how I can embed this? 回答1: ( updated 2019, removed unnecessarily costly method ) Just do: from IPython.display import Video Video("test

HTML5 video codec support

孤街浪徒 提交于 2019-12-03 02:09:26
What codecs will be supported with the HTML5 video tag? Will it vary by browser, or is there a spec of specific codec that will be supported? According to wikipedia : The current HTML5 draft specification does not specify which video formats browsers should support in the video tag. User agents are free to support any video formats they feel are appropriate. HTML5 is in draft format though and this may change. There is an ongoing debate about the suitability of various algorithms and it seems that currently not everyone involved is able to agree on an answer. The three major contenders are Ogg

I'm about to try to fully preload a video in HTML5. I use the attribute preload=auto but it does not preload the entire video... In Chrome, the video is only preloaded up to 2% and in Safari around 50%... Is it possible to force a full preload video with javascript? function addSourceToVideo(element, src, type) { var source = document.createElement('source'); source.src = src; source.type = type; element.appendChild(source); } var video; $(document).ready(function(){ video = document.getElementsByTagName('video')[0]; addSourceToVideo( video, "http://your-server.com/clip.ogv", "video/ogv");

Mobile Safari makes multiple video requests

I am designing a web application for iPad which makes use of HTML5 in mobile safari. I am transmitting the file manually through an ASP.NET .ashx file hosted on IIS 7 running .NET Framework v2.0. The essential code looks partly like this: // If we receive range header only transmit partial file if (context.Request.Headers["Range"] != null) { var fi = new FileInfo(filePath); long fileSize = fi.Length; // Read start/end index string headerRange = context.Request.Headers["Range"].Replace("bytes=", ""); string[] range = headerRange.Split('-'); int startIndex = Convert.ToInt32(range[0]); int
