H.264 format has been applied to the video data due to its higher compression efficiency,more friendly network adaptability,more effective abilities against mistakes and information loss. Therefore,a video player software suitable for H.264 format was designed and developed with FFmpeg toolkit. The testing result indicates the software can decode and play in various formats.%视频数据在各种数据中有着不可替代的作用，在视频数据量大，网络环境复杂的情况下，如何显示视频数据就成为重点。H.264格式因为具有更高的压缩效率，更友好的网络适应性，更有效的抗击错误和信息丢失的能力，已经被应用于视频数据中。因此设计了一款针对H.264格式的的视频播放软件，该款软件基于FFmpeg工具包进行开发，经过试验验证能够很好地进行多种格式的解码及播放。
