While Microsoft appears to have a robust video capture API for Windows Phone 8, it appears that any videos captured must be stored in the application's local storage, which is not accessible from the File Explorer when the WinPhone 8 device is connected to a Windows 8 PC.
Also, the app cannot store the videos anywhere the user could easily copy them from the phone. It is limited to its own isolated file system. This stackOverflow posting explains how the Win8 phone is locked down:
Windows Phone 8: Media file access
So, I can capture and store a video, but how do I get it off the phone to somewhere a user can manipulate it?
If you want those captured video off your phone then you can email/share it using ShareMediaTask & then can get that video out off the phone.
May be its not worth your requirement but if the purpose is to get it out off phone then it will help.

I have a device with a hard-coded NFC tag that opens an Android app based on an Android Application Record (AAR). Basically it calls an Android app to open with type android.com:pkg and payload com.something.Something.
I have researched on how to launch my Windows Phone app with that existing tag, but in the end I have only found that Windows Phone can launch an app if the NFC tag is adequately programmed to open the Windows Phone app ID or the custom protocol registered in my app. But it is very important that I use the existing NFC tag which opens the Android app ID.
What is curious is that my Windows 10 Mobile detects this existing NFC tag to want to open the app when I touch it with my phone and prompts me if I want to launch an app? But the app with that ID isn't installed so I did a research on how to put this app ID on my Windows Phone app but in the end I only got deployment errors.
Android Application Records (AAR) cannot be used to launch Windows apps. Windows uses a different system to launch apps (Launch Record). The main probem is that Windows uses a different scheme to identify apps (not a Java package name as Android does). Moreover, Windows apps cannot be set to be automatically launched based on the data contained in an AAR, hence, it's not possible to build some custom filter that starts your Windows app based on that AAR.
The workaround that's currently known seems to be what's discussed in Cross platform launch records with extra data on Windows Phone and Android. Though this requires modification of the data structures on the tag side.
I am playing alittle with windows phone 8.1 app creating. Using C# and phone emulator in VS2013. I have read on microsoft's page that i should be able to see OneDrive in standard file picker (msdn.microsoft.com/en-US/en-en/library/windows/apps/dn263258.aspx):
Use the built-in Windows features.
Whenever possible, use the Windows features and UI to host or interact
with OneDrive. For instance, use the file picker provided by the
Windows.Storage.Pickers namespace for opening and saving files. As
another example, have your app use the Windows application data APIs
to save smaller pieces of data across a user's devices.
I am using standard code from tutorial like:
openPicker.FileTypeFilter.Add("*");
StorageFile file = await openPicker.PickSingleFileAsync();
and it works but there is no OneDrive to choose. I have internet connection on emulated device and i am logged in to OneDrive.
Have you integrated your file picker with the OneDrive contract?: http://msdn.microsoft.com/en-us/library/windows/apps/hh465192.aspx
You can also use the Live SDK single sign-on feature for Windows Phone here: http://msdn.microsoft.com/en-us/library/dn631823.aspx This way, your app should work for your testing purposes because you are already signed in.
I hope this helps!
I added a uri association to my WMAppManifest.xml file in my Windows Phone 8 project and I'm able to successfully launch my app from within another app using LaunchUriAsync. I've also registered the same protocol in my Windows 8 project.
// windows phone 8 uri map
<Extensions>
<Protocol Name="myprotocol" NavUriFragment="encodedLaunchUri=%s" TaskID="_default" />
</Extensions>
On Windows 8, I am able to launch the app with by a simple hyperlink using my given protocol "myprotocol:".
On Windows Phone 8, I tried typing the protocol in the browser location bar, but I get an IE error saying this type of address is not supported. This makes me concerned I won't be able to launch my app from a web page simply by using my app specific protocol in the hyperlink.
Does anybody have any experience with this? Am I just paranoid?
fyi: here's the info on URI Associations in WP8
sometimes the simple answer is often overlooked.
Yes, everything is in place to function correctly. It appears to only be a restriction with IE Mobile.
I set up a web page on my server with a link click me and was able to successfully launch my app view IE Mobile on the emulator.
I have developed an app for windows phone in windows phone 7.Everything is fine in windows phone 7.
But when i upgraded it for windows phone 8,I found that the listbox of images is not showing in a page.After debugging
I found that media library is returning null,thats why listbox of images not showing any images
After searching over internet I found that for accessing media library images we have to first open windows phone's native photo app(native pictures).So I did it ,windows phone 8 emulator.Now it is working,but every time I have to open this native photo app,then I have to open my app,then only its working..Actually I dont have windows phone device,I just installed windows phone 8 sdk and tested it..
So my question is,Is there any way to directly access the media library with out opening native photo app,so that user dont have to open his native app every time before opening my app
You don't have to worry, that problem won't affect Windows Phone 8 devices, it only concerns the emulator.
Here's how I access media library's album and pictures:

You could check on the source code to know how to achieve your goal.
I am trying to capture video using a custom app on windows phone 8.
I am following the guidelines as per the link here.
I am clueless on how to set the resolutoin for the captured video. Currently it is being recorded at a resolution of 640x480 by default.
You are using the VideoCaptureDevice class which is the Windows Phone 7.5 API for recording video. That API by design is limited to 640*480.
If you want more control over the recorded video, you should use the new Windows Phone 8 API: AudioVideoCaptureDevice which has a SetCaptureResolutionAsync method. Of course, it will require a Windows Phone 8 device.
