Difference of OpenCore and Stagefright

Question

MY Understanding:

1) OpenCore / Stagefright both are multimedia frameworks in Android.

2) OpenCore was replaced with Stagefright.

What i do not understand?

Where can i find information like which version supports which media framework?

For example: I am not sure if Jelly Bean has support for both OpenCore and Stagefright?

Kindly Help!!!.

Answer 1

OpenCore was a multimedia framework developed by a company, Packet Video. OpenCore has been with Android from the first releases viz., Cupcake till the last release of Froyo.

In the later releases of Froyo, Stagefright was introduced under a build flag BUILD_WITH_FULL_STAGEFRIGHT. There was an additional control to enable/disable the Stagefright player through a system property.

Please have a look at line no. 629 of this file: https://android.googlesource.com/platform/frameworks/base/+/android-2.1_r2/media/libmediaplayerservice/MediaPlayerService.cpp

From GingerBread i.e. Android 2.3 onwards, only Stagefright is present in the AOSP distribution. Hence, JellyBean also has only the Stagefrght player.
