Sarxos api webcam issue - api

I am trying to access webcam by using sarxos api for webcam. When I run the program, I get the JNI error and exception in main thread like this:
NoClassDefFoundError: com/github/sarxos/webcam/WebcamPanel
How can I solve that error?

i have solved this error on my own. this was caused by not calling the open function of the webcam. i was trying to capture without opening the stream from webcam.

Unable to connect my Chromecast with my custom receiver

I'm following this guide: https://codelabs.developers.google.com/codelabs/cast-receiver#4 to create a custom receiver. Unfortunately when I try to use the cactool for testing: https://casttool.appspot.com/cactool/ I always get and error regarding my device id: Failed to cast, please try again later. In the browser I get:
My application id: 8FEE03DD
Status: Published
Chromecast serial id: 8917AD6D304
Any idea?
The "is_device_registered" error is caused by the Cast Debug Logger calls which don't work to run in a browser (since it isn't running on the Chromecast device and thus can't find it).
After many iterations and testing I have noticed the following common causes for "Failed to cast. Please try again" while using the code labs setup:
Chromecast caches the application data, so if you for instance updates the Receiver App URL the device has to be restarted before the new URL is used
Ngrok session times out (solved by restarting ngrok and updating the Receiver App URL in the Cast Developer Console)
Observe if you see GET requests from the Chromecast in the http-server console (my CC gen 3 has 'Linux armv71' etc in User-Agent). If so, the Receiver App is configured correctly and your issue is with the code (HTML, js, etc)

Access violation Error in IAP Simulation

I am trying to add IAP to a windows phone 8.1 app. I am currently trying to test it by using the WMAPPMANIFEST.
I can run code to get the listings from the file successfully, but whenever i try to simulate buying a product, the application crashes with the error
Exception thrown at 0x69E02F47 (Windows.ApplicationModel.Store.TestingFramework.dll) in G.exe: 0xC0000005: Access violation reading location 0x00000000.
Has someone experienced this error before, what is the solution?

Do not play songs from phone music library on device in WP8.1

I develop the music application for Windows Phone 8.1. I use BackgroundTask and access to phone music library. Application work fine on emulator with virtual sd-card, but do not work on device. When trying playback on device, an error occur:
Failed with error code System.UnauthorizedAccessException: Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))
This problem code, which errors occured. Code placed in foreground app for simplycity:
BackgroundMediaPlayer.Current.SetUriSource(new Uri("C:\\Data\\Users\\Public\\Music\\Ballroom\\Juan Camus - Now That The Love's Gone.mp3"));
BackgroundMediaPlayer.Current.Play();
Does anyone know how to solve this problem?
Using SetUriSource from the background task does not work when pointing to files that are not packaged with the app. If you want to play files from the user's library or SD card, you need to use SetFileSource or SetStreamSource instead. You can get the file from a path by calling StorageFile.GetFileFromPathAsync(path).
Unfortunately, this is not documented, so a lot of people will probably run into this (especially since the sample uses SetUriSource). What makes it even worse is the fact that using SetUriSource does work in the simulator and even on the phone, when deploying from VS. But it stops working when submitting to the store. So people will find out very late that their app does not work...
