I have been trying to play a simple smooth streaming video following the steps under
http://smf.codeplex.com/documentation "Building a Windows Phone Player". I have followed the steps exactly and am even using the Big Buck Bunny example. I'm using Visual Studio 2010, the libraries in microsoft-smf-binwp7-2.2012.0605.0.zip from smf.codeplex.com, and Microsoft.Web.Media.SmoothStreaming v1.1.837.146. I'm debugging on a windows 7 phone (and I have tried release as well), but the video never plays. The view loads, the player controls are visible, no time is set on the player and the play button is visible. I never get a MediaOpened or MediaPluginRegistered event. I have even tried setting AutoLoad and AutoPlay to true and clicking on the play button.
The only exception I get after the Loaded event is the following:
FileNotFoundException
File or assembly name 'System.Windows.debug.resources, Version=2.0.5.0, Culture=en-US, PublicKeyToken=7cec85d7bea7798e', or one of its dependencies, was not found.
As a side note, I have tried exactly the same thing on a Windows 8 Phone build to debug on a Windows 8 phone and it works just fine. Please help!

I'm creating a windows app , windows 8.1 app, using visual studio 2013.
i want to add a background music to it.
how to add it?
Do you mean music while the app is playing or music running when the app is in the background?
For both you'll set up a MediaElement running the music file you want to play.
Since the MediaElement will only play while it's in the visual tree you need to play a small trick to keep it running through all of the app's pages: instead of running the app out of a top-level page, create a root page with the MediaElement and a child frame, then run the app's pages out of the child frame. See my blog entry Frame of reference: keeping the music playing across pages for more details.
To play music when the app is in the background you'll need to declare the background audio task, set the MediaElement to BackgroundCapableMedia, and wire up SystemMediaTransportControls. See the How to play audio in the background documentation on MSDN for details.
My Windows Phone XNA game calls Guide.BeginShowKeyboardInput to get the user's name. While the Guide's input screen is shown, if the user presses the Home or Search (hardware) buttons, the game is deactivated as usual - but if the user then presses the Back (hardware) button, the game should resume but it doesn't. Instead it shows the "Resuming..." message until Windows Phone gives up trying to resume the game and kills the process.
Please note:
My app is failing Microsoft certification because of this problem - I really need to fix it!
This only happens in my game when the Guide input screen is shown - when it's not shown, the game
resumes properly after being deactivated.
This problem only occurs when the game is run on WP7.x (verified problem on WP7.5 and
WP7.8) - although the game seems to resume properly on WP8 devices.
I've created a blank XNA game project, called Guide.BeginShowKeyboardInput and tested it using WP7.x devices, and this problem-behavior doesn't occur.
I've tested the game without enabling Music & my Trial License manager (they use timers) and it still does this.
Exact same behavior occurs in the emulator (resume-failure on WP7.x emulators, works fine on WP8
emulator)
I used threads to asynchronously download content during the loading screen - but they already completed and exited.
I don't believe other threads are running, although this seems like
it could be a thread-blocking issue.
Any other ideas on what could be blocking the game from resuming when the Guide.IsVisible or how to debug/resolve this problem?
The solution to this issue was simply to NOT use SuppressDraw when dealing with any operation that passes control outside of the app, e.g. Launchers, Choosers and the Guide.
Have you tried calling "Guide.EndShowKeyboardInput" in either the Deactivating or closing events?
So that the guide is closed before the app suspends, you do get 10 seconds to suspend so this might be worth looking into.
If you want the guide to re-show on resume, then in your state saving code just have a flag and open the guide if it's set.
I am developing apps for window phone 7 using phonegap. I am facing the problem when launching the apps in emulator. I can see the splashscreen but not the index page. I just see the white blank screen after splashscreen. While running on emulator I got message "this computer do not have required graphics processing unit configuration."
I test with other in built apps with visual studio for window phone. It work fine.
What is the problem? With my graphics or something else.
Did you set up your app to launch index.html. If you have change the tree it's not a problem. You can change it in CordovaLib, CordovaView.xaml, CordovaView.xaml.cs. In this one, you will find StartpageUri. Be sure that is pointing on your file
Flash CS6 won't display any AS3 projects while debugging anymore. When compiling for debugging it turns up white in the default "debug window" inside of Flash. If I right-click in the debugger window it says "Movie not loaded". No compiler errors are shown. The resulting swf file only runs if opened with the Flash Player from Finder.
This applies for all projects that I know have been working fine up until now. I've also tested to create a new, blank FLA on which I only draw a rectangle with the same result.
If, however, I select a Flash Player version prior to 10 (falling back to AS2) as the target for the test file containing only a rectangle, it does compile and show up fine.
I've uninstalled Flash and Flash Builder (and deleting any trace of the applications in the Library folders) and then reinstalled it multiple times without any result. I've also tried to uninstall Flash Player and Flash Player Debugger to no avail. For this I'm following the advice on Adobe's site and are using their Flash Player uninstaller applications, but it doesn't seem to uninstall all instances of the Players...
I believe the problem lies in the version of Flash Player Debugger that Flash uses internally to display the swf when debugging and it seems to somehow persist between re-installations. Is there a sure-shot way to reset this entirely?
Has anybody encountered this problem before?
I finally found the problem myself. It seems like the Chrome extension called FlashFirebug randomly causes these issues. When I deactivated the extension Flash started working properly again.
I was wondering if the format is really supported. I am developing a simple WP7 application which contains a MediaElement such as the one shown bellow:
For the sake of testing, I subscribed for the MediaFailed event and it fires always.
If I try to open the file in the browser, it opens successfully. If I put the same MediaElement in a regular SL application - it runs. If I give some .wmv file to the MediaElement in the WP7 app - it runs. (http://files.ch9.ms/ch9/5baa/ea2aeba2-9dcc-4565-942a-9e6101655baa/DevKid_ch9.wmv).
Got any ideas?
One thing to watch is that video won't play if you're connected using USB to the Zune software.
I just tried your video using this IronRuby script - it plays fine.
For more help, you can check out the Channel9 application on codeplex - that works well.
Windows Phone 7 supports the MP4 container, but only supports a certain set of codecs. I believe this list is a pretty accurate list of what's supported.
It seems that you can't play mp4 files when Zune is running. However, you can still debug your application by connecting to your phone using WPConnect.exe which by default is installed to C:\Program Files\Microsoft SDKs\Windows Phone\v7.0\Tools\WPConnect. You'll need to close Zune before running WPConnect, but after you have run it, you should be able to F5 in Visual Studio and the the debugger running your code on the phone.
One other thing to keep in mind is that Windows Phone 7 requires the file (or URL) extension to match with the codec, so for mp4 files you need to have file name ending with .mp4, otherwise it won't play.
