  • fastest ffmpeg without caring about quality

    31 mai 2019, par RedDeath

    I would like to convert any video into .mp4 as fast as possible without caring about quality loss. I have used the next commands with which I have been able to finish the process in 37 seconds for a 10 second video.

    -vcodec h264
    
-crf 32
    
-preset ultrafast

    However 37 seconds is still too long for a 10 seconds video. Is there any improvements that I can do to the command in order to reduce the execution time ?

    Edit (Extra info) :

    I’m using FFmpeg Android (implementation 'com.writingminds:FFmpegAndroid:0.3.2') even though commands usually work for any FFmpeg (with a few variants depending on the FFmpeg version).

    The command used in my case which gave me the fastest result so far is :

        mFfmpeg.execute(
    
        arrayOf(
    
            "-i" , videoCopy?.path,
    
            "-vcodec", "h264",
    
            "-crf", "32",
    
            "-preset", "ultrafast",
    
            "-y", uploadFile?.path), 
    
        object : ExecuteBinaryResponseHandler() { ... }

    Which for regular FFmpeg command would be

    "-ffmpeg -i {video?.path} -vcodec h264 -crf 32 -preset ultrafast -y {uploadFile?.path}"

    Where video is my original video File and uploadFile is the File where I want to save the result into.

    In a Samsung J3 (SM-J320M, you can find its specifications online) such command takes the aforementioned 37 seconds.

    After executing such command the first onProgress message returned by FFmpeg prints :

  • Issue in concatenating two video files using FFMPEG

    12 mai 2014, par intrepidkarthi

    I am trying to concatenate two mp4 files taken from gallery. I am getting issue with process execution failure. I have added the code and the error log. Using the ffmpeg library taken from guardian project.

    I am running this in Samsung Galaxy S3 device.

    The error is thrown in this particular line.

    ProcessBuilder pb = new ProcessBuilder(cmds);
    
pb.directory(fileExec);
    
Process process = pb.start();  

    When I replace the last line above with this,

    Process process = Runtime.getRuntime().exec("chmod 777 "+cmds.toArray(new String[cmds.size()]));

    It works with out the exception as shown below. But the output doesn’t seem to come.

    File concatenation Code :

        File fileVideoOutput = new File(getApplicationContext()
    
            .getExternalFilesDir("test") + "hello.mp4");
    
    fileVideoOutput.delete();
    

    
    File fileTmp = getApplicationContext().getCacheDir();
    
    File fileAppRoot = new File(getApplicationContext()
    
            .getApplicationInfo().dataDir);
    

    
    try {
    
        FfmpegController fc = new FfmpegController(fileTmp, fileAppRoot);
    

    
        ArrayList<clip> listVideos = new ArrayList<clip>();
    
        Clip clip = new Clip();
    
        clip.path = video1;
    
        fc.getInfo(clip);
    
        clip.duration = clip.duration;
    
        System.out.println("Clip1 duration " + clip.duration);
    
        listVideos.add(clip);
    

    
        Clip clip2 = new Clip();
    
        clip2.path = video2;
    
        fc.getInfo(clip2);
    
        clip2.duration = clip2.duration;
    
        System.out.println("Clip2 duration " + clip2.duration);
    
        listVideos.add(clip2);
    

    
        Clip clipOut = new Clip();
    
        clipOut.path = fileVideoOutput.getCanonicalPath();
    

    
        fc.concatAndTrimFilesMP4Stream(listVideos, clipOut, false, false,
    
                new ShellUtils.ShellCallback() {
    

    
                    @Override
    
                    public void shellOut(String shellLine) {
    

    
                        System.out.println("fc>" + shellLine);
    
                    }
    

    
                    @Override
    
                    public void processComplete(int exitValue) {
    

    
                        if (exitValue &lt; 0)
    
                            System.err.println("concat non-zero exit: "
    
                                    + exitValue);
    
                    }
    
                });
    
    } catch (Exception e1) {
    
        e1.printStackTrace();
    
    }

    Here is my ffmpeg commands as given in the ffmpeg tutorial page.

    ffmpeg -i input1.mp4 -c copy -bsf:v h264_mp4toannexb -f mpegts intermediate1.ts
    
ffmpeg -i input2.mp4 -c copy -bsf:v h264_mp4toannexb -f mpegts intermediate2.ts
    
ffmpeg -i "concat:intermediate1.ts|intermediate2.ts" -c copy -bsf:a aac_adtstoasc output.mp4

    FFMPEG library doesn’t seem to be working as expected. When I add commands and create output file using "touch" shell command file is being created. Still I am unable to see the output from ffmpeg as expected.
