问题 I have a high quality video which I cannot compress too much as it's going to be the base of a lot of image analysis whereby each frame will be redrawn into the canvas and then manipulated. I'm trying to preload the whole thing before playing it as I can't have the video stop, buffer and continue. Is there an event which I can listen for which signifies that the whole video has preloaded before I commence playback? Here's how I'm doing it in JS/jQuery: this.canvas = this.el.find("canvas")[0];

阅读更多关于 How to detect supported video formats for the HTML5 video tag?

I am making an application in HTML5 using the video tag, in the application the user chooses a video file and I play that file. This all happens locally because I only link to that file in the user's machine. I want to allow only formats the browser can play to be played in my application, and to show an error for unsupported formats. The problem is that different browsers can play different formats.

阅读更多关于 Is there a way to use DRM on HTML5 video?

问题 Since Flash is losing ground I would like to know if there are ways to protect html5 videos with DRM (H264, .ogg and WebM). 回答1: On the W3C FAQ on HTML5 it states: Is there support for digital rights management (DRM) in HTML5 video?
