android - 使用ffmpeg Android在视频中设置动态水印

Question

我正在使用此命令将图像叠加到视频中。

ffmpeg",i", inputVideoPath,"-i", imageToOverlay,"
-filter_complex",overlay=10:10","-strict", "-2","-b:a" ,"32k",
"-r","15","-preset", "ultrafast",outputVideoPath

我们可以将动态值设置为“overlay=x:y”以及“imageToOverlay”，即图像路径吗？

Answer 1

试试这个命令

 //  test with watermark.png 128x128, add it to /sdcard/videokit/
String[] complexCommand = {"ffmpeg","-y" ,"-i", "/sdcard/videokit/in.mp4","-strict","experimental", "-vf", "movie=/sdcard/videokit/watermark.png [watermark]; [in][watermark] overlay=main_w-overlay_w-10:10 [out]","-s", "320x240","-r", "30", "-b", "15496k", "-vcodec", "mpeg4","-ab", "48000", "-ac", "2", "-ar", "22050", "/sdcard/videokit/out.mp4"};
