How to hold last frame in mediaplayer in Windows phone 8.1..?

I am using mediaElement to play videos in an app in Windows phone 8.1. When I am moving to next channel by pressing the right
arrow (which I have placed), its showing the first frame of the video before moving on to next video.
I actually want to show the frame at the time when the video was switched to next channel. How can I do this..?

Hi Jose,
Well, if you have a media file you can get its thumbnail from its StorageFile using StorageFile.GetThumbnailAsync method:
https://msdn.microsoft.com/en-us/library/windows/apps/windows.storage.storagefile.getthumbnailasync.aspx
If you really need to grab the first frame from a video in your MediaElement, you have to write an MFT in C++ to do this. Please refer to this thread and read Rob's suggestion for details:
https://social.msdn.microsoft.com/Forums/windowsapps/en-US/b3245a6c-23b5-4fff-a26b-1c0a8a87437c/grabbing-a-video-frame-to-make-a-thumbnail-in-a-c-xaml-windows-store-application?forum=winappswithcsharp

How can I transfer photos from an old Windows phone to an iPhone without a PC/Mac?

My mother has used a Windows phone for the last three years and has just upgraded to an iPhone. She doesn't have a PC or Mac. I have tried using MS OneDrive, which automatically uploads pictures taken with the Windows phone, similar to the iCloud Photo Library. However, using the iOS app to access those pictures, they have been shrunk down to a tiny fraction of their original size. They are unusable, a blurry, pixilated mess. And you can only save one at a time to the iPhone camera roll. Is there any other way to do this? I obviously want the full size photos to be copied over to the iPhone, en masse.
Thanks for any help.

I was going to suggest Dropbox but apparently they announced a Windows Phone app in November and it isn't out yet. The following appears to be a 3rd party app that will work to get things from a Windows phone to Dropbox and may be worth investigating: http://betanews.com/2014/03/06/theres-finally-a-great-dropbox-client-for-windows -phone/

How to create an S/MIME message in Windows Phone 8?

Hi!
I am communicating with a backend that requires me to create on the Phone a message that follows the S/MIME standard. I have stored a public key in the IsolatedStorage on the phone, but I am not sure how to build the S/MIME message since there doesn't seem
to exist any support for this in Phone 8 .NET framework.
Does anyone have suggestions on how to accomplish this? There seems to be very little X509 support in Phone 8. I have talked to a fellow developer that did the Android app, and they used Bouncy Castle SMIME libraries (javamail) but these have not been ported
to the C# version of Bouncy Castle.
Any ideas? I have never built an S/MIME message before, but as far as I can tell it is a simple header-body design where the body can have a nested structure, and the body can also be encrypted.
I ahve checked the
http://social.msdn.microsoft.com/Forums/en-US/netfxnetcom/thread/74e4711e-1f66-43a7-9e3b-bc9cfbcd1b73/ post, and they use cms classes that doesn't exist in Phone 8... :(
best regards

If you want S/MIME support on Windows Phone, take a look at MimeKit (https://github.com/jstedfast/MimeKit) and MailKit (https://github.com/jstedfast/MailKit).
MimeKit is a very fast and robust MIME parser implementation written in C# that uses BouncyCastle for the low-level cryptography and supports both S/MIME v3.2 and PGP.
MailKit builds on top of MimeKit to add SMTP, POP3, and IMAP support.
Both projects are completely open source and free for commercial use.

How to open a web browser from an windows phone app

Hi everyone,
I am pretty new to Windows Phone 7, and now what I am trying to do is to create a simple app. When a user click to start this app, a browser will open and show the content of a webpage from a specific address.
I tried to use a webbrowser object, but it seems like that doesn't sport cookies. So I need my app to open a real web browser (maybe IE mobile) to do the job.
Thank you.

copying from stackoverflow: "If you want to embed a browser window inside your application then use the WebBrowser control. Add an instance of the WebBrowser control to your form then you can reference it in code using the name you
give it. (Default name is "webBrowser1")"

How can I import a file into my Windows Phone 8.1RT App?

Hi All,
I'm running into a bit of an issue associating my app with a custom file type. Users create a file using my app and upload it to their OneDrive for sharing. So I then want to give the users the ability to download the file from a share link and
have that file open automatically in my app. I've got the appropriate declarations set and file type associations, but I'm getting a file access exception when I try to open the file. Whats the best way to import a file into my app? Here's
the code I've got so far:
protected override async void OnFileActivated(FileActivatedEventArgs args)
var path = args.Files[0].Path;
var name = args.Files[0].Name;
StorageFile newFile = await StorageFile.GetFileFromPathAsync(path);
await newFile.CopyAsync(ApplicationData.Current.LocalFolder, name.Substring(0, name.Length - 4));
The path comes back as
C:\Data\Users\DefApps\APPDATA\Local\Packages\microsoft.microsoftskydrive_8weke\LocalState\OpenWithTempFolder\e68c261-db3b-472d-a8b7-93427450\File Name.extension
and the exception is
Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))
Clearly I'm trying to access the file in an inappropriate way, so what's the best way to get the file into my app's local storage?

You have the StorageFile in arg.Files[0] already. Just use that rather than getting its path and then trying to create a new StorageFile from it.
var path = args.Files[0].Path; // <= Path is unnecessary and unhelpful
var name = args.Files[0].Name;
await args.Files[0].CopyAsync(ApplicationData.Current.LocalFolder, name.Substring(0, name.Length - 4));
See my blog entry Skip the path: stick to the StorageFile for more details.

How do I sync my data from a windows phone to an iPhone 4 iOS 7.1.2

i need help syncing my data from a windows phone to a iPhone.

Assuming you have your Windows Phone data synced to Microsoft's Outlook.com, or even Gmail,
You can setup the Outlook.com or Gmail account in Settings->Email, Contacts, Calendars->Accounts->Add Account
And it will download all data from there. Email, contacts, etc..
Other than that, you will have to export all your data from the Windows phone, and then use iTunes to Sync whatever is relevant onto the iPhone.

How to start a loop back proxy in Windows Phone 8 and have all app and internet traffic routed via it

I want to develop a proxy in windows phone 8 that will handle all data traffic emanating from phone(i.e. browser and Apps). The following procedures were carried out
a) Edited the Wifi settings http proxy and port to the loop back proxy running in the phone(i.e. 127.0.0.1) and the port in which we brought up the loop back proxy
b) We browsed pages and no request landed on the loop back proxy in the phone
Loop back proxy in phone is built using StreamSocketListener
Another observation is that:
If we edit Wifi settings http proxy and port to a http/https proxy running on server then when we browse pages from windows phone we are getting the requests to server. Why is this difference?
Is there a limitation to run http/https proxy on mobile phone as loop back proxy.
But there are apps in the market for windows phone that behaves as HTTP proxy like
http://www.windowsphone.com/en-us/store/app/smartproxy/75da629b-c0f3-4999-86a3-9559181d1299
Any help on the same would be appreciated

Hi,
Thanks for your reply and we have used StreamSocketListener waiting on a port and ip is given as loopback.The same settings are done for Wifi access point but when we browse any page in IE the requests are not landing on to the loop back proxy.Any idea on
the same would be highly appreciated

How can I hold a frame of a clip?

I want to hold the first frame of a clip, then play the clip, then hold the last frame. Seems like there's some time remapping tools somewhere but I can't figure this out.
I can't just take a screen shot and set that as the still because this is one window in the video and there's other stuff going on.
Basically there are going to be four windows each with a video track. One will play, then freeze and the next will begin.
Any thoughts on how to do this? I don't want to have to go into After Effects if I can help it.
Thanks!

To get a still of a clip in the timeline, go to the frame you want to freeze, select 'f' to match frame back to that clip and frame in the Viewer, select Sift+N' to create a Freeze of that frame, insert that into the Sequence.
... same for freeze at end.
You said there's four windows - you mean on one screen? ... then I'd create 4 sequences, possibly of the same duration each; one each for the 4 frames you want. They would each start with a freeze, roll on, then freeze at the end. Make these SEQs longer than you need.
One at a time, put them into the Viewer (don't double-click them) and edit them onto 4 tracks of master SEQs.
Apply sizing and motion to each of those. Control-click the clips in the timeline and select 'Open In Viewer' to see their motion tabs.
This method helps separate the roll off/to a freeze from the editing & motion (resizing/zooming etc.)
Hope that helps.
Neil.

How do I loop back from the first frame to the last frame?

Hi there,
I'm currently working on the framework for a product viewer.
I have:
a movie clip called 'viewer_mc' which contains the images take from different angles of the product. The actionscript generates a script on the last frame of this that returns it to frame 1.
a button instance called 'autoplay_btn' which plays through the movie clip from whatever the current frame is, and stops on frame 1.
a left and right button which serve to move the movie clip frame, to give the appearance that the product is rotating.
I have succeeded in getting it to:
have the movie clip play through once, return to frame 1 and stop.
have the buttons return functions when held down, that move the frame in the movie clip using nextFrame and prevFrame commands. The right button successfully loops round to frame 1 and continues functioning to give the appearance of continual rotation.
The last problem I am experiencing is getting the left button to act in the corresponding manner, going from the first frame to the last and continuing to function.
Here is my actionscript so far:
import flash.events.MouseEvent;
var lastFrame:Number = viewer_mc.totalFrames;
var thisFrame:Number = viewer_mc.currentFrame;
var backFrame:Number = viewer_mc.currentFrame-1;
1. This is the part that gets it to play through once before returning to the first frame. I think perhaps the problem I am experiencing is because of the 'viewer_mc.addFrameScript(lastFrame-1, toStart)' part i.e. although I'm holding the left button, its returning to this script and therefor getting bounced back immediately to the first frame. However, there is no flicker on the screen which you might expect if this were the case
Note - as this is a generic product viewer which I can use as a template I am using lastFrame etc. as opposed to typing the value in
function toStart (){
          viewer_mc.gotoAndStop(1);
viewer_mc.addFrameScript(lastFrame-1, toStart);
2. This is the functionality for the autoplay_btn that will play through a rotation / return the viewer to the initial (frontal) view of the product (frame 1).
autoplay_btn.addEventListener(MouseEvent.MOUSE_DOWN, autoplay);
function autoplay (ev:MouseEvent):void{
          var startFrame:Number = viewer_mc.currentFrame;
          viewer_mc.gotoAndPlay(startFrame);
3. This is the functionality of the right button, which when held, moves the movie clip to the next frame via the 'rotateRight' function based on the 'nextFrame' command. It loops back round to the first frame due to the 'viewer_mc.addFrameScript(lastFrame-1, toStart)' script generated on the last frame of the movie clip, as is desired.
right_btn.addEventListener(MouseEvent.MOUSE_DOWN, rightDown);
function rightDown(e:Event){
    stage.addEventListener(MouseEvent.MOUSE_UP,stoprightDown); //listen for mouse up on the stage, in case the finger/mouse moved off of the button accidentally when they release.
    addEventListener(Event.ENTER_FRAME,rotateRight); //while the mouse is down, run the tick function once every frame as per the project frame rate
function stoprightDown(e:Event):void {
    removeEventListener(Event.ENTER_FRAME,rotateRight); //stop running the tick function every frame now that the mouse is up
    stage.removeEventListener(MouseEvent.MOUSE_UP,stoprightDown); //remove the listener for mouse up
function rotateRight(e:Event):void {
    viewer_mc.nextFrame();
4. This is the functionality of the left button, which when held, moves the movie clip to the prev frame via the 'rotateRight' function based on the 'prevFrame' command. And this is where the problem lies, as although it works for getting the movieclip back to frame 1, it does not loop round to the last frame and continue functioning, as is wanted.
left_btn.addEventListener(MouseEvent.MOUSE_DOWN, leftDown);
function leftDown(e:Event){
    stage.addEventListener(MouseEvent.MOUSE_UP,stopleftDown); //listen for mouse up on the stage, in case the finger/mouse moved off of the button accidentally when they release.
    addEventListener(Event.ENTER_FRAME,rotateLeft); //while the mouse is down, run the tick function once every frame as per the project frame rate
function stopleftDown(e:Event):void {
    removeEventListener(Event.ENTER_FRAME,rotateLeft); //stop running the tick function every frame now that the mouse is up
    stage.removeEventListener(MouseEvent.MOUSE_UP,stopleftDown); //remove the listener for mouse up
I'd imagine it is probably my logic for this part that is really letting me down - I can do a similar function in actionscript 2, but am trying to learn actionscript 3 just to move with the times as it were, and struggling a bit. Still this is only a few days in!
function rotateLeft(e:Event):void{
          if(thisFrame==1){
                    gotoAndStop(viewer_mc.totalFrames-1);
          } else{
          viewer_mc.prevFrame();
Any help you can give me would be gratefully received. For an example of the effect I am trying to achieve with the autoplay button etc. I recommend:

function leftDown(e:Event){
    stage.addEventListener(MouseEvent.MOUSE_UP,stopleftDown); //listen for mouse up on the stage, in case the finger/mouse moved off of the button accidentally when they release.
    addEventListener(Event.ENTER_FRAME,rotateLeft);//while the mouse is down, run the tick function once every frame as per the project frame rate
function stopleftDown(e:Event):void {
    removeEventListener(Event.ENTER_FRAME,rotateLeft); //stop running the tick function every frame now that the mouse is up

The definition of the rotateLeft function is where the problem lies I think - I've taken out my poor attempts at doing the logic from the previous post. If I were to write it out long-hand the statement I want to write is: 'If you get to frame 1 and function rotateLeft is called go to the end of the movie clip'.
The reason I have to use the viewer_mc.totalFrames-1 definition in the addFrameScript call is the addFrameScript function is 0 based i.e. if you want to call frame 1 of the movieclip you have to return a value of 0 in the addFrameScript (or such is my understanding of it anyway). As such, the last image in the movie clip will need to be the view obtained at 360 degree rotation, which is of course the same view as at 0 degree rotation. As a consequence, the last frame in the movie clip is superfluous for the user, but necessary for the overall effect to be achieved. And, in addition, to keep up the effect of a 360 degree view when the rotateLeft function is called it needs to skip that last frame to go to the lastFrame-1 (or totalframes-1), or in other words, the view of the image prior to completing the full 360 rotation.
the variables thisFrame and lastFrame are defined at the very top of the script. Like you said they might need to be defined or called on again elsewhere.
