| 摘 要： | 由于无线网络具有数据传输速率低、带宽不稳定、误码率高等缺点,所以如果想在无线网络上传输清晰流畅的视频流数据,必须有先进的视频压缩技术和高效健壮的传输协议的支持。H.264作为首选的视频压缩标准,但在手机视频的实际应用中,还存在诸多手机的播放器本身并不支持H.264编码格式的视频播放。以此为据,阐述了将开源H.264解码器移植到Symbian手机中的实现过程以及需要注意的几个实际问题,对其他手机平台提供了可借鉴的经验。

| Abstract: | Because of the low data transmission speed,unstable bandwidth,and high data bit error rate of wireless networks,it is necessary to get the support of the advanced video compressed technology and efficient transmission protocal if the clear and fluent transmission of video streaming data is needed.Although H.264 is the first recommended video compressing standard,many media players in smrat phone don′t support the H.264 coding mode in the actual video application of cellphones.The process to realize the transplantation of H.264 decoder into Symbian smart phones and the practical problems to which people should pay more attention are elaborated. |
