ffmpeg-按持续时间向视频添加、缩放和设置多水印的可能性
ffmpeg-按持续时间向视频添加、缩放和设置多水印的可能性,ffmpeg,Ffmpeg,我有一个视频/path/to/video.mp4 现在我想每6秒放置一个水印。我使用命令作为： "ffmpeg" -i /path/to/video.mp4 -i /path/to/watermark-1.jpg \ -i /path/to/watermark-2.jpg \ -i /path/to/watermark-3.jpg \ -i /path/to/watermark-4.jpg \ -i /path/to/watermark-5.jpg \

我怎么了？您必须分别缩放每个水印
"ffmpeg" -i /path/to/video.mp4
-i /path/to/watermark-1.jpg \
-i /path/to/watermark-2.jpg \

显式设置映射时，仅输出映射流。让FFmpeg在此处自动选择流 必须分别缩放每个水印
