Helping to make the SDL cross-platform library more attractive for mobile/Android developers, the latest SDL2 code has an initial OpenSL ES implementation. OpenSL ES is the Khronos Group’s effort as an industry-standard sound library for embedded hardware while offering up 3D positional audio support, optional integration with OpenMAX, audio effects, and other advanced sound capabilities. More details may be found on Phoronix with a diff of the merge here.
The Khronos Group just wrapped up another tour in Asia. Slides from the visit and a few photos are available online.
Android released an updated version of the Android NDK bringing it to revision 7. “Android NDK r7 includes a number of build system improvements and bug fixes, but most importantly it gives you access to two new sets of APIs”, wrote Xavier Ducrohet on the Android Developers Blog. The two new Khronos Group APIs are: OpenMAX AL 1.0.1 for Low-level streaming multimedia, which provides a direct, efficient path for low-level streaming multimedia; and OpenSL ES used for audio decoding into PCM. Release notes are available on the Android Developers website.

Google’s recently announced Android 4.0 platform, and related Ice Cream Sandwich SDK, include many new media capabilities. One very nice addition is the introduction for low-level streaming multimedia. To support this low-level streaming, the platform introduces a new native API based on the Khronos OpenMAX AL 1.0.1 API. This API is implemented on the same underlying services as the platform’s existing OpenSL ES API, so developers can make use of both APIs together if needed. Tools support for low-level streaming multimedia will be available in an upcoming release of the Android NDK. Learn more about OpenMAX AL on the Khronos Group website.
