摘要
AVS-M是《先进音视频编码》系列标准AVS的第七部分,是无线网络与手机等移动设备视频编解码的规范和标准,高效快速的编解码器对AVS-M标准能否得到推广和应用有着极其重要的作用。介绍了AVS-M标准参考代码移植到Symbian平台的方法和要解决的问题,并针对Symbian手机平台对AVS-M标准参考代码给出几种优化方法,实现了AVS-M在NOKIA 6670上解码QCIF格式达到15帧/秒,基本上能够实现在Symbian平台的流畅播放,对推广AVS-M有很大的帮助。
AVS- M coding standard is the seventh part of advance audio and video coding standard. It is a video coding standard for wireless network, handset and other mobile devices. One key for broad application of AVS- M is to implement efficient and rapid software AVS- M encoder. Introduces the AVS - M standard reference code transplanted to the Syrnbian platform and the method to solve the problem, and Symbian mobile platform against the AVS- M standard reference code gives several optimization method. Implementation of AVS- M in 6670, NOKIA decoding QCIF format to achieve 15 frames/s. Basically, achieve a further Symbian platform fluent broadcast,it is useful to promote AVS-M.
