This paper proposes a video watermarking algorithm of MPEG-2 based on the FFMPEG system,solving the inevitable problem of video coding and decoding during video watermarking.It transforms the watermark image and its attributes into binary bit stream working as the actual watermark embedded into the video.So that it doesn't need to provide size information of original watermark during extracting.Embed a flag sequence at the beginning of every frame that needs embedding to recognize the embedded frames,and need not to code the video again.Experimental results indicate that this watermark algorithm is convenient and sufficient,and has excellent invisibility and robustness.
