MediaElement in Windows Store App - windows-8

I am creating an app for a radio station and I am using MediaElement and MediaControls. But when I try to Stop or Pause the playback it does not work. After searching in MSDN I found that Start, Stop and Pause will not work in this case "Stop cannot be called while the timing engine drives media playback."
I manages to stop the playback by assigning null to mediaelement.Source but then the same problem appears in Start().
Can anyone explain what is going on here? Thank you!

Finally I made it work without Pause Stop and Start. I just changed the mediaelement.PlaybackRate from 0 to 1 and that seems to work perfectly

Do you use the Windows Store JavaScript or C# language?
If you make a Javascript Windows Store app, you can just use the html player. This got a play, mute and play status.
<audio controls="controls">
<source src="horse.ogg" type="audio/ogg">
<source src="horse.mp3" type="audio/mpeg">
Your browser does not support the audio element.
</audio>

play instagram video fetched from public api

I've searched a bit here on SO to find a way to show instagram video using the public api ?__a=1 method. I've found a question that have pointed me into the right direction but not at all.
after I get the user media, I'm checking in my vue app if the resource is a video or an image and if is a video I show an html5 player where I'm binding the url that is obtained form the public json api. What I'm facing is that the player will not reproduce the video, but if I use the url into the browser, an html5 player is loaded with the related video that will start playing.
The video urls returned are something like this one:
"https://scontent-mxp1-1.cdninstagram.com/v/t50.2886-16/117420353_635186773777278_7723572524374891239_n.mp4?_nc_ht=scontent-mxp1-1.cdninstagram.com&_nc_cat=106&_nc_ohc=nI6tYDeag-0AX8MtmoL&oe=5F3C077B&oh=a47046b1aabf223f16c4c66526e20e57"
I've tried to remove all the part after the .mp4 file extension but this will not work, so I suspect that all the url is needed. Is there a way that I can use to reproduce video in my app?
After many tryes unfortunately I didn't figured out how to use my own HTML5 player so I've used a simple solution. An <iframe> with the url set will let the vido play into the app, this exclude me from the ability to remove the download button or controls from the player but at the moment it's the only way I can implement to achieve my scope.
(1) Your link works okay for me in a video tag:
<video width="640" height="480" >
<source src="https://scontent-mxp1-1.cdninstagram.com/v/t50.2886-16/117420353_635186773777278_7723572524374891239_n.mp4?_nc_ht=scontent-mxp1-1.cdninstagram.com&_nc_cat=106&_nc_ohc=nI6tYDeag-0AX8MtmoL&oe=5F3C077B&oh=a47046b1aabf223f16c4c66526e20e57"
type="video/mp4">
</video>
(2) It even works okay in this random demo that uses vue.js.
With no demo page of your problem the solution is a guess...
Make sure that your own site URL starts https:// or else change the video src to http://...etc.
Make sure your server (settings?) isn't somehow blocking you from loading the file.
If still failing, show us the problem via some link to your testing page.

Safari plays audio only once when using <amp-audio>

I'm trying to have a short sound that I can play over multiple times by simply the play button on AMP. On Safari (desktop and mobile) the sound will only play once.
The sound is supposed to be triggered when the user clicks a button.
I've followed the amp documentation for the amp-audio and the audio events
<amp-audio preload="none" id="audio" controlslist="nodownload" hidden>
<div fallback><p>Your browser doesn't support HTML5 audio</p></div>
<source type="audio/mpeg" src="/media/shortSound.mp3">
<source type="audio/ogg" src="/media/shortSound.ogg">
</amp-audio>
The "native" audio button is hidden and is triggered by clicking the following button (with the on:tap event)
<div class="button" on="tap: audio.play" role="button" tabindex="0"></div>
I have also tried using absolute URLs in vain and using the pause function before play but to no avail.
Note: Unfortunately there is no .load event to circumvent the problem like with HTML5 on Safari (which is how I got to play it on Safari on the non-amp version)
Actual result: The sounds play once (the first time I click it). The rest of the time nothing happens, no message in the console either. What am I doing wrong?
I have found the issue was with the mp3 encoding of my files. It uses VBR instead of CBR, the problem doesn't happen when using CBR encoded mp3 files. To check your encoding I recommend using https://checkmate.gissen.nl/download.php
EDIT: IT was actually because Safari uses HTTPRange to get its resources instead of a classic get method.
Hopefully the loop attribute on <amp-audio> can help here: https://amp.dev/documentation/components/amp-audio/?format=websites

Vimeo autoplay not working Safari 11

I've loaded this embed code to our website on the homepage.
https://player.vimeo.com/video/254985863?autoplay=1&loop=1&autopause=0&background=1" width="1903" height="500" frameborder="0" webkitallowfullscreen mozallowfullscreen allowfullscreen>
You can see the site here
The video autoplays perfectly everywhere except Safari. In Safari it just loads the cover image. I am guessing that safari 11 thinks the video has sound but it doesn't. Is there a setting to show safari that this is a muted video?
I believe this is a very recent Safari bug, possibly in 11.0.3 or 11.0.2. I've just reported this to Apple, please do the same so that they get on it: https://www.apple.com/feedback/safari.html
It's definitely treating the video as if it has sound - if you set the 'Settings for this website' to 'allow all autoplay' then it will work - which is useless because the default is 'Stop Media with sound'
We were experiencing the same issue with Safari (only) for background video and I have been paying close attention to this thread since it was raised back in February (I did report the issue to Apple as suggested) but upon checking the live site again today this is now working correctly once again.
Neither the Vimeo videos or website code has been changed but the videos are now playing in Safari as expected (previously it was displaying a static image only). I am still running the same version of Safari as I was before, when this was an issue (11.0.3), so I can only assume that something has changed on the Vimeo embed side of things. Perhaps they have updated the mute code.
It is now working correctly again, but I can find no mention of anything changing on the Vimeo side.
on https://www.apple.com/safari/
"Stop auto-play videos.
Safari prevents unexpected and unwanted videos with audio from automatically playing while you browse. Just click the play button if you want to view them. Have a favorite site where you always want videos to play? Use per‑site settings in Safari to enable media auto-play."

Inline video in mobile Safari?

I've been attempting to find a method for playing video inline in mobile safari for awhile now.
I know this is possible and has been achieved (see link)-
http://www.raptmedia.com/project/philips-designed-play-drives-mobile-video-engagement
However, I am unable to determine how this is done. I've tried manipulating iframes but this alone doesn't seem to have any impact.
I've included a js player for cross browser compatibility and used it within an iframe, no luck in mobile:
<div class="vid"> <video id="vid01" class="video-js vjs-default-skin" controls="controls" preload="none" width="600px" height="600px">
<source src="video.mp4" type='video/mp4'/> <source src="video.webm" type='video/webm'/>
<source src="video.ogg" type='video/ogg'/> <track kind="captions" srclang="en" label="English" />
</video> <script> var myPlayer = _V_("vid01"); ` </script>` </div>
I know this is an old question, but it ranks high in my Google search and I can at least answer the question posed above, so I'll add this in case other people come across it: why does it work on that particular page?
I looked at it, and it doesn't really play inline video. On my iPhone, it preloads a ton of JPG frames and then "plays" them like a movie, while playing an mp3 audio track behind it. So they are just faking it, basically. Still not able to play the video inline on the phone.
The only solution I know is based on the drawImage function of the canvas tag... I spotted the basics here on SO but there's some fun left for the reader :D, in a few words, You hide and play the video and at the right freq You render the current frame into a canvas, some attention is needed for the audio sync. It works better than expected.
Here is a basic sample, and here another one where I try to apply some webkit based filters.
Hope it helps, have fun!
You can use something like this library to make it work: https://github.com/bfred-it/iphone-inline-video
It basically uses an audio tag to drive the video by seeking to the current time, so you can have the frames updated without having to play the video.
The good news is that iOS 10 will support this, so no more hacks are going to be needed: https://developer.apple.com/library/prerelease/content/releasenotes/General/WhatsNewInSafari/Articles/Safari_10_0.html#//apple_ref/doc/uid/TP40014305-CH11-DontLinkElementID_12

VideoJS - Autoplay in Mobile

The autoplay do not working in mobiles (Android, iOS). The autoplay work in mobiles? Exist another plugin in html5 to show videos and start automatically in mobiles?
There is a workaround for this. What I've done is dynamically append the video element, and have the autoplay setup option set to true.
The trick is to place an element in front of the video player that initiates the action to append the video element. You can't use video.js's poster since that isn't available until videojs is instantiated. I haven't tried to trigger that event manually in javascript, but that might be worth a try.
Relevant Question
As of January 24th, 2017
HTML5 video tags can autoplay on android if the video is muted. You would need to include the muted and autoplay attributes in the tag to make it work as intended.
Here is a link to the article: Autoplay on Chrome for Android as of version 53
No, autoplay does not work in mobile devices. A user action (click, etc) is required in order to begin playback in order to avoid excessive bandwidth use.
