Powerful media functions
Android 4.0 added the
powerful media functions to enrich the applications.
Low level streaming
multimedia : Android 4.0 enables the
direct path for low level media streaming with a new set of native API based on
khronos OpenMAX AL 1.0.1 (standard for media library portability). Low level
streaming allows the applications to keep complete control over the media before
passing to the presentation layer.
New Camera Functions: Android 4.0 enables the new camera functions by
which apps can take better resolution images even during the vedio capture.
Transform the images
and videos : A set of
high-performance transformation filters let developers apply rich effects to
any image passed as an OpenGL ES 2.0 texture. Developers can adjust color
levels and brightness, change backgrounds, sharpen, crop, rotate, add lens
distortion, and apply other effects
Audio Remote Control : A new set APIs for audio remote control for
media applications. The media applications can add the audio remote functions
to control the functions using the audio remote events.
New media codec and
containers : Android 4.0 adds support for additional media types and
containers to give developers access to the formats they need. For high-quality
compressed images, the media framework adds support for WebP content. For
video, the framework now supports streaming VP8 content. For streaming multimedia,
the framework supports HTTP Live streaming protocol version 3 and encoding of
ADTS-contained AAC content. Additionally, developers can now use Matroska
containers for Vorbis and VP8 content.
