Coming In WP8.1: Video Editing, Screen Recorder, SDCard APIs, Possible Miracast Support And More

WIndows Phone 8.1 new APIs

The leaked Windows Phone 8.1 SDK revealed lots of new features in the upcoming Windows Phone 8.1 platform. Exploring the SDK and its documents reveals more and more new features. WP8.1 will support media editing(video editing) API, screen recording API, SD card API to developers enabling them to create new set of apps.

Also, Microsoft is planning to add External Display support that would allow a user to share their phone screen from their Windows Phone device to a nearby device, either wirelessly or using a cable. However, Microsoft has mentioned in the document that if the required work is completed before the release, the phone may also be multi-screen aware and could wirelessly share its content with an external display, such as a big screen TV, by using Miracast.

Read about the above new APIs in detail after the break.

Screen recorder:

Windows Phone (code-named “Blue”) provides APIs that you can use to create an app that records images or videos of the phone’s screen activity. This way games can upload and share in-game activities. This feature is enabled through enhancements to the Windows.Media.Capture APIs already available to Windows Store apps.

Media Editing:

Windows.Media.Editing provides a set of Windows Runtime APIs that can be used to create a simple or rich editing application for the phone. This can be a simple video trimmer or a more complex timeline editing application that allows effects to be added via Microsoft Media Foundation Transforms (MFTs). A core concept of the editing API framework is that editing a media file does not alter any existing source media files. The goal of the APIs is to create a new composition, called a Clip, which contains defined chunks of source clips for audio and video. The properties of this clip are defined by capturing a set of user input. A simple examples of this the basic trim operation where a source clip is loaded and the user picks a new beginning and endpoint in the video, which defines a Clip or MediaClip.

External Display Support:

External Display features would allow a user to share their phone screen from their Windows Phone (code-named “Blue”) device to a nearby device, either wirelessly or using a cable, without having to understand the complexities of the technologies leveraged to accomplish it. With Windows Phone (code-named “Blue”), a developer or RSP can mirror the phone screen to a PC via USB cable. If the required work is completed before the release, the phone may also be multi-screen aware and could wirelessly share its content with an external display, such as a big screen TV, by using Miracast.

SD card:

Windows Phone 8 support read-only access to the SD card; Windows Phone (code-named “Blue”) provides read/write access. An app can only see and work with files when it has registered as a handler for that file type. Apps can’t see the Photos, Music, or Video folders, even when those folders are also stored on the SD card.
