给视频添加水印，水印按视频的宽和高的较小值缩放。

图片合成视频
ffmpeg -loop 1 -t 3 -i last.png -loop 1 -t 3 -i tail_watermark.png -filter_complex "[0]boxblur=5[v0];[1]fade=in:st=0:d=3:alpha=1[v1];[v0][v1]overlay=(W-w)/2:(H-h)/2:shortest=1" -y output.mp4

给视频加上动图水印(APNG)

ffmpeg -i E9NESE0WW0YE1179_org.mp4 -filter_complex "movie=watermark.png:loop=0,setpts=N/(40*TB)[animation];[animation][0]scale2ref=iw/5:main_h*ow/main_w[wm][vid];[vid][wm]overlay=W/56:W/56:shortest=1[out];[out]scale=trunc(iw/2)*2:trunc(ih/2)*2[rs]" -map "[rs]" -map 0:a -c:v libx264 -b:v 512k -c:a copy -movflags +faststart -y output.mp4

每4秒隔1秒显示水印

ffmpeg -i E9NESE0WW0YE1179_org.mp4 -filter_complex "movie=watermark.png:loop=0,setpts=N/(40*TB)[animation];[animation][0]scale2ref=iw/5:main_h*ow/main_w[wm][vid];[vid][wm]overlay=W/56:W/56:shortest=1:enable='lt(mod(t, 5), 4)'[out];[out]scale=trunc(iw/2)*2:trunc(ih/2)*2[rs]" -map "[rs]" -map 0:a -c:v libx264 -b:v 512k -c:a copy -movflags +faststart -y output.mp4

使用图片给视频加上动态水印

ffmpeg -i E9NESE0WW0YE1179_org.mp4  -loop 1 -framerate 40 -i watermark%2d.png -filter_complex "[1][0]scale2ref=iw/5:main_h*ow/main_w[wm][vid];[vid][wm]overlay=W/56:W/56:shortest=1:enable='lt(mod((t\), 5), 4)'[out];[out]scale=trunc(iw/2)*2:trunc(ih/2)*2[rs]" -map "[rs]" -map 0:a -c:v libx264 -b:v 512k -c:a copy -movflags +faststart -y output.mp4
