在ffmpeg监护人项目中使用叠加视频过滤器（android）

Question

First, im a beginner in FFMPEG so please bear with me.

Im using this library and successfully combined an audio and a video :D

However, i keep failing when i tried to insert an image/watermark over a video.

This is the code im using :

public MediaDesc combineVideoAndImage (MediaDesc videoIn, MediaDesc image, MediaDesc out, ShellCallback sc) throws Exception
    {
        ArrayList<String> cmd = new ArrayList<String>();

        cmd.add(ffmpegBin);
        cmd.add("-i");
        cmd.add(new File(videoIn.path).getCanonicalPath());

        cmd.add("-vf");
        cmd.add("movie=" + new File(image.path).getAbsolutePath() + " [logo];[in][logo] overlay=10:10 [out]");

        cmd.add("-strict");
        cmd.add("-2");

        File fileOut = new File(out.path);
        cmd.add(fileOut.getCanonicalPath());

        execFFMPEG(cmd, sc);

        return out;
    }

Those code will generate this cmd :

ffmpeg -i VIDEONAME.mp4 -vf "movie=LOGONAME.png [logo];[in][logo] overlay=10:10 [out]"
-strict -2 OUTPUTNAME.MP4

I have tested this CMD on ubuntu 13.10 64bit, with latest FFMPEG installed and t succeed.

But it does not in my android project. It does not catch/throw any error/exception, the program running normally and the file is created but has nothing in it (0 byte)

Any help is appreciated. Thanks for your help :D

Answer 1

Try with following command

ffmpeg -i input.mp4 -i watermark.png -filter_complex "overlay=10:10" -codec:a copy output.mp4

i have tested it on android and it is working perfect.
