  • FFMPEG command on Android Jave Process does not fully execute

    8 novembre 2014, par user2491598

    The issue I am having is very strange. I have an FFMPEG executable binary library installed on my Android and I am trying to execute this command

    ffmpeg -loop 1 -i /storage/emulated/0/image.jpg -i /storage/emulated/0/input.mov -filter_complex '[0:v][1:v] overlay' -shortest /storage/emulated/0/output.mp4

    and my JAVA code looks like

    try {
    
            Runtime.getRuntime().exec("chmod 700 " + mFfmpegPath);
    
            cmd.add(mFfmpegPath);
    
            cmd.add("-loop");
    
            cmd.add("1");
    
            cmd.add("-i");
    
            cmd.add("/storage/emulated/0/image.jpg");
    
            cmd.add("-i");
    
            cmd.add("/storage/emulated/0/pizza.mov");
    
            cmd.add("-filter_complex");
    
            cmd.add("'[0:v][1:v] overlay'");
    
            cmd.add("-shortest");
    
            cmd.add("-vcodec");
    
            cmd.add("-libx264");
    
            cmd.add("-strict");
    
            cmd.add("experimental");
    
            cmd.add("/storage/emulated/0/output22.mp4");
    

    
            final ProcessBuilder pb = new ProcessBuilder(cmd);
    
            pb.redirectErrorStream();
    
            final Process p = pb.start();
    
            Log.i("FFMPEG","stdError= " + getSTD(p.getErrorStream()));
    
            p.waitFor();
    
            return run;
    
        } catch (IOException e1) {
    
            // TODO Auto-generated catch block
    
            e1.printStackTrace();
    
        } catch (InterruptedException e) {
    
            // TODO Auto-generated catch block
    
            e.printStackTrace();
    
        }

    For some reason I the execution does not fully finish and it stops. It does not even create an output file in my Android storage. Here is the log file from the process stream

  • FFMPEG scale and crop in single command

    26 mars 2016, par The Hungry Androider

    I’m using FFMPEG on Android using the following lib : http://writingminds.github.io/ffmpeg-android-java/

    This is the command I’m using :

    "-i " + path + " -vf scale=480:360,crop=360:360:0:00 -strict -2  -preset ultrafast " + fileOutPath

    My goal of this is to scale the image down to 480x360, then crop it to 360x360 from (0,0) (top left corner). HOWEVER, what ends up happening is that it crops from the vertical-center. So for example if you were to take a vide of three blocks on top of each other filling the entire screen, the crop would eventually show just the middle block, whereas I desire the top block.

    Any ideas as to what I’m doing wrong ?

    My ultimate goal from all of this is to get a square video of size 360x360.

  • Why calling libav* library doesn't have same quality as ffmpeg command line ?

    10 mai 2016, par seaguest

    I am using the ffmpeg 3 to do the video format conversion, it works fine when I use the command line mode, but when I call the libav* library, I get a audio quality loss problem (there is a lot of noises in the audio).

    Here are the two files :

    mv.webm - original file
    mv2.mp4 converted with libarary , a lot of noises

    Here is the probe information for the mv.webm :

    $ ffprobe mv.webm

    I checked the log printed by command line mode and calling code mode, the setting looks like the same, here are the logs :

    Checking the setting section, crf=23.0 for both (the rest are exactly the same), but the output bitrate are different (the audio for calling code mode has a lot of noises), how is that possible ?

    Why the command line mode and use libav* library mode with same setting, but have different output ?
    What should I do to call libav* library to get lossless video conversion ?
