Embedding Youtube videos not working with Node-webkit

I have an embedded youtube video in my nw.js app. The preview for the correct video shows up properly but when I click to play it I am met with the following error:
An error occurred, please try again later
All of the videos in the app get this error, except for one that gets this puzzling error:
The following video contains content from the International Basketball Federation
When I click these videos, I can see the first split second of the video before the error shows up.
I tried enabling/disabling the webkit plugin in the manifest:
"webkit": {
"plugin": true
}
and I tried using the Javascript Player API as suggested by in this post. However I still get the same errors.
How can I get these videos to play properly?
Here is the HTML (I'm using angularJS and the video is in a modal window) that displays the video:
<script type="text/ng-template" id="myModalContent.html">
<object width="100%" height="600px" data={{video}}>
</object>
</script>
I also tried copying this example using the Javascript Player API and even tried using the same video as the example but I'm still getting the same error.
Thank you very much for your time. Let me know if you need anything else from me or if I am being unclear.
Ok so the issue was the ffmpegsumo.dll. At first I tried replacing it with the dll from chrome 39 and 42 and that did not fix my issue. After replacing the file with the ffmpegsumo.dll from Chrome 38.0.2125.122, my issue was fixed and videos played as expected.
Chrome 38.0.2125.122 ffmpegsumo.dll 32 bit
Chrome 38.0.2125.122 ffmpegsumo.dll 64 bit
You need the flash plugins in the plugins directory at the same root level as the package.json NPSWF32_13_0_0_214.dlland NPSWF32_14_0_0_125.dll. This with the above will enable Flash.
Had the same problem in Linux 64 bits using Yeoman Node Webkit Generator (https://github.com/Dica-Developer/generator-node-webkit/wiki/Getting-Started)
Just fixed it by adding the so lib:
$ cp nwjs/nwjs-v0.12.0-linux-x64/libffmpegsumo.so dist/Linux64_v0.12.0/

Ruby on Rails capture webcam video and audio

Is there any gem out there that can interact with users webcam to capture video and audio and upload it to the server?
Have you heard about navigator.getUserMedia()? That could the trick. More info: http://www.html5rocks.com/en/tutorials/getusermedia/intro/
They talk about it in the Mobile Web Development course in Udacity (lesson 10).

Have you tried headshot ?
I just tried it yesterday, but ran into some trouble with the flash player, not beeing able to set permissions for camera use
try it out, its easy to add to your application, maybe you'll make it work.
and better backup your files before.

Submission and video related query using Xcode

Des anyone know what is meant by this - I could understand if I was using a piece of media embedded but I'm viewing a quicktime file through the web using a webview so any clarification would be great?
main pages for videos are incorrectly formatted for iPhone
Thanks :-)
They required that a sample URL was submitted - the video format was fine. Hope this helps anyone with similar issue come back.

MediaPlayer.Play method throwing DRM exception?!

I'm trying to add background music to my XNA 4-based Windows game. When I do
Song bgm = Content.Load<Song>("bgm");
MediaPlayer.Play(bgm);
in the MyGame.LoadContent method, I get an InvalidOperationException with the message "Song playback failed. Please verify that the song is not DRM protected. DRM protected songs are not supported for creator games." The song is in MP3 format and is not protected. I tried using a WAV instead and the result was the same.
It seems I'm not the only one having this problem. But the closest thing I've found to a solution is "use XACT".
Any ideas?
Edit: Also, why is my code snippet not syntax highlighted? It's highlighted in preview.
The problem in my case was that I had uninstalled Windows Media Player. For what it's worth, I'm running Windows 7 Professional 64-bit. I reinstalled WMP via the Windows Features dialog and the problem went away immediately. I didn't even have to restart.
The problem for me was that I was missing the ID_CAP_MEDIALIB capability in my WMAppManifest.xml.
<Capability Name="ID_CAP_MEDIALIB"/>
Hope this helps.

Buffering in Blackberry

Currently I am working on the application for which I have to use audio buffering. Please tell me how I can achieve this task as I am trying myself.
read this Buffer and play streamed media
Also, there's a great example in the Blackberry SDK, which shows buffered playback of a MP3 file.
Take a look in the 'samples' folder of JDE/Eclipse Plugin.
