html5-video

问题 Is there a good way to detect if a client browser allows inline media playback for HTML5 video? Update I am not trying to simply detect video support. I am trying to detect if a video can only play fullscreen or also inline. Because on the iPhone safari iOS videos only play in fullscreen, but on iPad videos may be played inline. And by inline I mean in the page without switching to fullscreen. 回答1: In iOS10 you can now have a video play inline if the playsinline attribute is added to the

问题 I'm in the process of working out what the best way is going to be to do the following: I have a bunch of CCTV footage files (MP4 files, ranging from 4MB-50MB in size), which I want to make available through a web portal. My first thought was to stream the file through Web API, so I found the link below: http://www.strathweb.com/2013/01/asynchronously-streaming-video-with-asp-net-web-api/ After implementing a sample project, I realised that the example was based on Web API 1, and not Web API

问题 I am running into a huge issue with autoplaying videos on iOS11 devices (at least tested on iphone 7 ios 11.2.5 safari ). When the change in policy about autoplaying videos arrived, our autoplaying videos stopped working. Our app heavily depend on videos. We deeply changed all the steps for users to interact with videos to make sure they're not blocked and they're now muted by default and autoplay is triggered after user gesture. so videos DO autoplay muted and we thought we were doing after

问题 I've always wondered whether whitespace before a DOCTYPE matters, but I can't seem to find any definitive information on the web. People say not to do it, but I can't see what effect it's likely to have, or even if the spec says it must be like that. I can't figure out if it triggers compatibility mode in IE or anything annoying like that. The reason is, in my (crappy asp.net) code, I would much prefer to write: <%@ Page language="c#" Codepage="65001" AutoEventWireup="true" %> <%@ OutputCache

问题 We have an intro page which plays a html5 video before the main site content is displayed. The video has a white background so it integrates seemlessly with the page background. However, in the chrome browser the whole video has a gray background. Apparently, these questions from 2011 indicate this was/is a bug in chromium. They also state the bug was gone in the latest chrome update. However, I downloaded the latest chrome version, 27.0.1453.110 m, and the problem is still there? html 5-

问题 I would like to show a small clip from a long video file that is over 10 minutes long. This segment of video would start at time offset /seek time of 90 seconds and would have a duration of 45 seconds .

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 3 years ago . I am trying to trim the length of a video within the browser, from either the beginning or the end.
