Streaming mp4 in Chrome with rails, nginx and send_file

阅读更多关于 Streaming mp4 in Chrome with rails, nginx and send_file

问题 I can't for the life of me stream a mp4 to Chrome with a html5 <video> tag. If I drop the file in public then everything is gravy and works as expected. But if I try to serve it using send_file , pretty much everything imaginable goes wrong. I am using a rails app that is proxied by nginx, with a Video model that has a location attribute that is an absolute path on disk. At first I tried: def show send_file Video.find(params[:id]).location end And I was sure I would be basking in the glory

Video requiring asp.net authentication not working on iOS 10

阅读更多关于 Video requiring asp.net authentication not working on iOS 10

问题 On Safari in iOS 10 my video doesn't work, only showing the play-icon. I serve the video via an asp.net server, which checks to make sure the user has logged on and have access to the video. Only, on iOS 10 the server will respond with 401 Unauthorized! Doing some testing with the code below, I found that safari on iOS 9 sends the ".ASPXAUTH" cookie - but safari on iOS 10 doesn't! <video crossorigin="use-credentials" controls autoplay="autoplay"> <source src="/Server/GetVideo.ashx?id=123"/> <

At first, I run below javascript: <script type="text/javascript"> var options = JSON.stringify({'maxSize': 320, 'videoQuality': 6, 'noaudio': true}); ogg.encode(options); </script> Then I have below html: <video id="video1" width="500" controls="controls" > <source src="Rio2Trailer.mp4" type="video/mp4"/> <source src="Rio2Trailer.ogv" type="video/ogg"/> <source src="Rio2Trailer.webm" type="video/webm" /> The browser does not support HTML5 video. </video> I tried adding AddType video/webm .webm

Detect if ios11 device is in low power mode to prevent bad UX on normally correctly autoplaying video

阅读更多关于 Detect if ios11 device is in low power mode to prevent bad UX on normally correctly autoplaying video

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 already days of work. But there's an issue: Last week, I was testing on my girklfriend 11.2 iphone the

Gapless Transition from Video to Video using html5

阅读更多关于 Gapless Transition from Video to Video using html5

问题 I am trying to create a feature where a user can change (back and forth) between multiple videos while maintaining a single consistent audio. Think of being able to watch a concert from multiple angles but listening to a single audio. The trouble I am having with this feature is that there can not be a lag between the changes in video or the audio will no longer sync with the videos (especially true after multiple changes). I have tried two methods, both using html5 only (I would prefer not

Basically I'm doing everything as described in answer to this SO question . The problem with UiWebView was that if relative path was set to src, video for some reason couldn't be loaded

Video displayed in ReactJS component not updating

阅读更多关于 Video displayed in ReactJS component not updating

I'm new to ReactJS (0.13.1), and I've created a component in my app to display HTML5 video. It seems to work perfectly but only for the first selection. The video that is actually displayed and playing in the page doesn't change when you switch from one video to another (when this.props.video changes). I can see the <source src='blah.mp4' /> elements update in the Chrome inspector but the actually rendered video in the page doesn't change and keeps playing if it was already. Same thing happens in Safari & Firefox. All the other elements update appropriately as well. Any ideas? Anyway my
