随着网络的快速发展,对高质量视频的实时传输提出了更高的要求,然而由于智能手机处理能力低、内存小等硬件配置因素,使得嵌入式媒体播放器中的视频数据无法自适应网络状况,最终导致视频数据在传输过程中大量丢失,降低接收到的视频图像质量.在此提出基于Android的视频流自适应算法,该算法可动态探测网络带宽,自动适应网络拥塞状况,制定平滑的数据传输带宽,缓解网络拥塞,根据传输带宽控制视频编码和视频传输速率,提高视频传输质量.%With rapid development of network technology, a more critical requirement is proposed for the real-time transmission of the high-quality video. However, the video data in the embedded media player can not fit the network situation self-adaptively due to the low processing function, low memory and limited hardware configuration of the phone. It finally leads to the loss of video data in the processof transmission and the quality of video received image is lowered. A video adaptive algorithm based on Android is proposed in this paper. The algorithm can detect network bandwidth dynamically, offers smooth data transmission bandwidth, ease jamming status, control video coding and transmission rate according to the transmission bandwidth, and improve video transmission quality.
