摘要:
FFmpeg是一个开源跨平台多媒体数据解决方案,常被移植到各种嵌入式系统中。将FFmpeg移植到Android系统中,能够增加Android系统对编解码格式标准的支持,但由于目前手机处理能力低,内存小等硬件配置因素,严重影响FFm-peg对音视频流的解码效率,导致解码出的音视频数据无法同步。通过研究基于时间戳的多媒体音视频同步算法模型,将其引入到FFmpeg中,并在Android平台进行算法实验。实验证明,基于时间戳多媒体音视频同步算法模型能够有效地保证多媒体数据的同步
Abstract:
FFmpeg is an open source multi-media data solution. It is independent to platform and often be ported to a variety of embedded systems. Porting FFmpeg to Android platform will increase the codec standards supported by Android. However, the low processing power, low memory and limited hardware configuration of the mobile phone, seriously affected the codec efficiency of FFmpeg. And finally led to audio and video data can not be synchronized. By studying the timestamp-based multimedia audio and video synchronization algorithm model and introduced it into FFmpeg, this paper validated the effectiveness of it on Android platform. The experiments showed that the timestamp-based model of multimedia audio and video synchronization algorithm can effectively ensure the synchronization of multimedia data
