Research on the Synchronized Transmission Algorithm of Embedded FFmpeg Multimedia Data

In order to achieve synchronized transmission among FFmpeg multimedia data streams on Android platform, this paper analyzed the time information of multimedia data stream and provided the elements which composed it. Then the author proposed a new method to implement the synchronized transmission of multimedia on Android platform. The synchronized transmission algorithm combined negative feedback control mechanism, without acquiring exact time of the system, but just only focus on timestamp of the audio and video data, this guaranteed the multimedia data synchronization. Finally, this new method has been transplanted and implemented on Android.
