In the past, we can enjoy the multimedia entertainment on personal computer, but now multimedia appears in handheld devices anywhere. The advances of multimedia with the network technology bring much more user experience and value-added services offerings, such as YouTube, Live Streaming, Video Conference and so on. This paper proposes an efficiently lightweight multimedia framework. The framework could be used in various Android handset systems. Just install in application layer simply and do not re-build the Android image. Out of the shackle and dependency from Android system, it could achieve downloadable purpose. The efficiently lightweight multimedia framework is based on the Stagefright Player framework which Google bring up in Android 2.2. Stagefright would be the mainstream multimedia framework in Android. Efficiently Lightweight Stagefright (EL-Stagefright) inherits Stagefright’s functions such as playback, hardware decoding, stop play and support http streaming playback etc. Add two functions in EL-Stagefright, one is a trimming function that support MP4, 3GP container format by technique of frame reference. Another is live video streaming player which contain a FLV parser and RTMP protocol in EL-Stagefright multimedia framework.
