Capture Android Screen And Create Video Programmatically

In Android/Java, Is there any code example to capture the screenshot of a computer with good frames per second programatically and create video? I'd like a tutorial or full source

Solution 1:

Check the following link https://code.google.com/p/java-remote-control/

in this project the owner has created a java remote control i.e. he has captured the images from the remote computer and transfer to server and convert it to movies with different format all you need to understand what he has done and implement the same for all your needs. you can access the full source code with SVN client from the following URL

http://java-remote-control.googlecode.com/svn/trunk/

Also you can look for the Remote class in java which provides createScreenCapture method

Solution 2:

There is an app called Telecine that is open source that allows you to record screens - the code can be found at https://github.com/JakeWharton/Telecine. All credit is to Jake Wharton.

If you need an example, you can find one at Commonsware's github page - Mark Murphy has provided a sample app for both screen capture and screen recording using the MediaProjection APIs.

Solution 3:

you can capture the screen via using DDMS as adb runs and has permission to the framebuffer:

Solution 4:

As of Android 4.4, there is a screen recording feature accessible via adb.

http://developer.android.com/tools/help/adb.html#screenrecord

The screenrecord command is a shell utility for recording the display of devices running Android 4.4 (API level 19) and higher. The utility records screen activity to an MPEG-4 file, which you can then download and use as part of a video presentation. This utility is useful for developers who want to create promotional or training videos without using a separate recording device.

Solution 5:

Try this application from the market

** Does not work on Galaxy Nexus or Tegra 2/3 yet **

EDIT 28/11/2014

Lollipop has been released and provides a new Screen recording API

Screen capturing and sharing

Android 5.0 lets you add screen capturing and screen sharing capabilities to your app with the new android.media.projection APIs. This functionality is useful, for example, if you want to enable screen sharing in a video conferencing app.

The new createVirtualDisplay() method allows your app to capture the contents of the main screen (the default display) into a Surface object, which your app can then send across the network. The API only allows capturing non-secure screen content, and not system audio. To begin screen capturing, your app must first request the user’s permission by launching a screen capture dialog using an Intent obtained through the createScreenCaptureIntent() method.

For an example of how to use the new APIs, see the MediaProjectionDemo class in the sample project.
