Android screen video recording

How I should go about recording a video screen capture of an OpenGL application?

So far my plan 开发者_开发知识库of attack is to take individual screenshots then run it through a video encoder.

Does anyone here know of any sample code I can look at or has any suggestions of things I can look at?

I'm looking for the OpenGL app to capture in game footage and save it as video content.

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

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.
