使用ffmpeg添加视频水印，附为封面图

使用ffmpeg添加视频水印，视频包含封面图，水印作为封面图附加。

像这样的命令

ffmpeg -ss 0 -t 60 -i .\test2.mp4 -i logo_gray20p.png 
 -filter_complex "[0:V]overlay=x=W-w-20:y=10[out]"  -f mp4 test2_out.mp4

视频添加水印使用了“Stream #1:0: Video: png”，而不是logo_gray20p.png。输出信息包含“Stream #0:2 (png) -> overlay (graph 0)”。

输出

访问FFMPEG：如何为视频添加水印？

参考这篇文章，效果很好

代码修改为

 ffmpeg -ss 0 -t 60 -i .\test2.mp4 -i logo_gray20p.png  -filter_complex "[0:v][1:v]overlay=x=W-w-20:y=10[outv]" -map [outv] -map 0:a  -f mp4 test2_out.mp4
