Anyone know of a way to access an audio file that is protected with Basic auth when using a BackgroundMediaPlayer in WP8.1?
I've tried using the StreamingRandomAccessStream from How to play a video stream that requires authentication? but it doesn't work with BackgroundMediaPlayer. This is because SetStreamSource() needs to be run from the background agent, and I can't use a HttpClient in a Windows Runtime Component.
EDIT (2015-04-13):
I've now tried using a Windows.Web.Http.HttpClient but it never worked properly because of an apparent bug in the HttpClient stack: https://social.msdn.microsoft.com/Forums/windowsapps/en-US/07e551c1-37c0-4bd9-9d98-aa3fc90df974/windows-phone-8-portable-httpclient-causes-outofmemoryexception-downloading-large-file?forum=wpdevelop&prof=required#5eb62907-92cd-4643-8c74-9e6c2a30e464
The SM.Mono.Net repository has a solution, but doesn't work with files over TLS, which unfortunately makes it unusable for me.

I've got a Windows Store app that's a WinRT Phone/Desktop app (i.e. not a UWP app), targeting Windows 8.1 and up.
It's been on the store for several years now, but recently it stopped being able to connect with various web APIs and websites (YouTube, as well as my own site) using HTTPS.
I have a WPF version of this app as well, and this happened on that app recently as well, and to fix it I used System.Net.ServicePointManager. Unfortunately, in my WinRT environment, System.Net doesn't include ServicePointManager. In my WPF app, I did this, and it worked just fine:
ServicePointManager.ServerCertificateValidationCallback = delegate
{
Debug.WriteLine("returning true (the ssl is valid)");
return true;
};
// our server is using TLS 1.2
ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3 | SecurityProtocolType.Tls | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls12;
In doing some research around the internet, it seems that .NET 4.6 should include ServicePointManager, but I don't see any way to change (or even see) my version of .NET in the WinRT development environment.
I looked some more and found that a StreamSocket could be used to connect with TLS1.2... but that seems primarily designed to enable bluetooth communications, or communications to a web endpoint, but only by hostname... which is insufficient for me. I need to connect to an actual website, not just the base-level domain.
Trying this, I did the following:
StreamSocket socket = new StreamSocket();
string serverServiceName = "https";
socket.Control.KeepAlive = false;
url = "inadaydevelopment.com";
HostName serverHost = new HostName(url);
await socket.ConnectAsync(serverHost, serverServiceName, SocketProtectionLevel.Tls12);
text = await ReadDataFromSocket(socket);
I can include the code for ReadDataFromSocket() if necessary, but it seems to work, reading the data from the socket as expected when I point it at https://google.com. However, I can't seem to figure out how to point the socket at anything useful. The homepage of inadaydevelopment.com isn't what I want; I'm looking to consume a web API hosted on that server, but can't seem to find a way to do that.
Since the first parameter to the ConnectAsync() method is just HostName, the second parameter (remoteServiceName) must be the way to connect to the actual API or webpage I'm trying to connect to. According to the docs, that is The service name or TCP port number of the remote network destination... I haven't seen any example values for this parameter other than https and various numeric values, neither of which is going to get me to the API endpoint or webpage I'm trying to connect to.
So, with that super-long preamble out of the way, my question boils down to this:
Is there a way for me to use System.Net.ServicePointManager in my WinRT app like I do in my WPF app? If so, how?
If not, how can I use StreamSocket to connect to the exact web service or webpage I want to connect to, rather than just the top-level host?
If that's not possible, by what other means can I consume web content using TLS1.2?
Thanks in advance for any help or advice.
Use Windows.Web.Http API instead of System.Net.Http API.
System.Net.Http does not support TLS1.2 but Windows.Web.Http does in WinRT apps.
I have an application that uses MapBox's API to stylize the underlying map which uses Google Places. This all worked perfectly fine when running in IOS 7+, but when I try testing this in IOS 8, it immediately crashes with the following error message:
Terminating app due to uncaught exception NSInternalInconsistencyException, reason: 'The layout constraints still need update after sending -updateConstraints to MapView at {0,0}-{320x444}.
RMMapView or one of its superclasses may have overridden -updateConstraints without calling super. Or, something may have dirtied layout constraints in the middle of updating them. Both are programming errors.'
I have been looking around the Web and Stack for a while but have been unable to find anything helpful unfortunately. Any suggestions?
I deleted all Mapbox framework / headers / lib from my project and reinstalled the latest (1.4.1) mapbox static library (libMapbox.a) and the Headers, and everything was ok after that without changing a line of my code.
I'm developing a hybrid app (using PhoneGap) for openHAB. At the moment I'm struggling to build a connection from my hybrid to the OpenHAB runtime. Any suggestions?
The intended way to connect to the openHAB runtime is the REST API which is described in detail in the wiki (see https://github.com/openhab/openhab/wiki/REST-API).
You could also have a look at the implementations of the native Android client (see https://github.com/openhab/openhab.android) or the greenT HTML5 application based on Sencha Touch (see https://github.com/openhab/openhab/tree/master/distribution/openhabhome/webapps/greent).
Hope this helps,
Thomas E.-E.
The openhab has a REST API implemented as a bundle. this can be accessed via the URL "http://openhabip:8080/rest/".
If you want to access the items and implemet your own UI you can use "http://openhabip:8080/rest/items" with HTTP GET, POST ,PUT.
Otherwise you can use the "http://:8080/rest/sitemaps" and use the openhab provided sitemaps.
The details are in https://github.com/openhab/openhab/wiki/REST-API
I've posted a similar question about the more general case, but this question deals specifically with RTMP.
We have an Adobe AIR app written in AS3 that can view live video streams from other parties. That being said, when trying to call BitmapData.draw() on one of those remote video streams (technically we're calling ImageSnapshot.captureImage()), we're getting a 2123 error - a security sandbox exception. I've seen a lot of people refer to a real simple configuration in the AMS that will allow this to work for RTMP streams, but they keep posting broken links, links to posts that only vaguely mention this configuration, etc. The one thing I did find is something that I'm having trouble applying:
http://help.adobe.com/en_US/FlashMediaServer/3.5_SS_ASD/WS5b3ccc516d4fbf351e63e3d11a11afc95e-7ec3.html#WS5b3ccc516d4fbf351e63e3d11a11afc95e-7fcb
To make the above work, I've tried setting audioSampleAccess and videoSampleAccess both to "/", but to no avail. On the AMS, in Application.xml, I've set these configurations:
<FolderAccess>true</FolderAccess>
<AudioSampleAccess enabled="true">*</AudioSampleAccess>
<VideoSampleAccess enabled="true">*</VideoSampleAccess>
I've also seen references to setting up a wide-open cross-domain policy file, but I've seen people emphasize that it's not necessary, and I don't see any clear mention of where on the server that policy file needs to be. I have, however, started setting NetStream.checkPolicyFile to true, and I have placed a cross-domain policy file in the root directory of the website itself (as opposed to the AMS).
Please don't just give me another link, unless it's to a quick, clear explanation. How do you configure the AMS to allow people to capture screenshots from RTMP video streams? For the above article, I've tried setting videoStreamAccess and audioStreamAccess both to "/", and even it didn't work. We also need to be able to do this for P2P RTMFP streams, but that's really a different question. Thanks.
I have following FMS code to fix that error in application.onConnect method:
client.videoSampleAccess = "/";
client.audioSampleAccess = "/";
I'm trying to port an existing web app (ActionScript 3 only project) to AIR, to run as a standalone application. One of its features is opening urls in a browser window. But calling navigateToURL(new URLRequest(url)) throws this SecurityError:
SecurityError: Error #2193: Security
sandbox violation: navigateToURL:
app:/AIRDigE.swf cannot access
http://www.youtube.com/watch?v=xCPwAr0xnGE.
at global/flash.net::navigateToURL()
when run from Flash Builder 4.
Googling doesn't really help me with this specific error number.
Adobe's reference on Security Sandboxes states that any AIR application running with Security.sandboxType==Security.APPLICATION (which my application uses) should be able to connect to any domain, but apparently that doesn't count for me.
Any ideas?
Thanks, Frank
Sorry folks, this morning I found the answer myself: the url that I passed into the URLRequest had a space in front of it (it was loaded from an xml feed that is evidently producing faulty urls).
So it seems that a url with an invalid protocol causes that error, and putting a trim() around the url fixed it.
I was getting this error because of using double backward slashes in the web link like "http:\\www.youtube.com"
Where as I supposed to use "http:*//*www.youtube.com"
try using URLRequest with navigateToURL
navigateToURL(new URLRequest("http://www.youtube.com"));
UPDATED:
navigateToURL(new URLRequest("http://www.youtube.com"),"blank");
