    5 juin 2013, par Nitish Singla

    I want to merge IMAGE + AUDIO and convert them into video using FFMPEG library,i compiled the library successfully,and got libfmpeg.so.but getting problem to execute the ffmpeg command through java code.This is command which i am using...
    "ffmpeg -i image8.jpg -i file.m4a -acodec copy test.mp4"
    if i execute this ffmpeg command through CMD,my video.mp4 file is successfully created,but if exceute same command through my Activity,it doesnot create any file.

    MY CODE IS :

    public class Mpeg extends Activity 

    static {
    

    
    System.loadLibrary("ffmpeg");
    

    
}

    super.onCreate(savedInstanceState);
    
    setContentView(R.layout.activity_mpeg);

    File mf = Environment.getExternalStorageDirectory() ;

        String livestream = mf.getAbsoluteFile()+"smile.png";
    

    
    String folderpth = mf.getAbsoluteFile()+"RABBA.MP3";
    

    
    //String output="/home/saicomputer/game.mp4";
    

    
    String output = new File(Environment.getExternalStorageDirectory(), "video.mp4").getAbsolutePath();
    
    Log.i("Test", "Let's set output to " + output);
    

    
    String cmd="ffmpeg -i "+ livestream +" -i "+ folderpth +" -acodec copy "+ output;
    

    
     Log.e("chck plzzzzz", "after "+ cmd);
    

    
    //String jaiho="ffmpeg -i image8.jpg -i file.m4a -acodec copy test.mp4";
    

    
    try{
    

    
    Process p = Runtime.getRuntime().exec(cmd);
    

    
    }
    
catch(Exception e)

  • JavaCV record video in Android

    11 janvier 2017, par wyx

    I want to record video quiet and without preview in Android. So I choice MediaRecorder but I could record only without preview but what make me crazy is that when MediaRecorder start or stop it will with a sound dee.... I try many methods about that . But I think it perhaps sth related to the OS of the mobile. So I try JavaCV because I also want to have a Live function in my app.

    But JavaCV spent me to too much time to solve some strange problems because it’s my first time to do sth about C++ src and video.

    Just compile group: 'org.bytedeco', name: 'javacv-platform', version: '1.3' as the README.md ,I even can’t build my apk.

    Error:Execution failed for task ':app:transformResourcesWithMergeJavaResForDebug'.
    
> com.android.build.api.transform.TransformException: com.android.builder.packaging.DuplicateFileException: Duplicate files copied in APK org/bytedeco/javacpp/macosx-x86_64/libusb-1.0.dylib
    
    File1: /Users/wyx/.gradle/caches/modules-2/files-2.1/org.bytedeco.javacpp-presets/libfreenect/0.5.3-1.3/736d65a3ef042258429d8e7742128c411806b432/libfreenect-0.5.3-1.3-macosx-x86_64.jar

    And then I modified it according this issuse
    use this to repalce. It can build the apk. But the can’t run.

    So I want to know a comfortable method to achieve my goal : recode video quiet and without preview. And Live real time ?

    I found ffmpeg4android is a prefect library to run ffmpeg command. I just use it to compress videos from MediaRecorder But I don’t how to do use it to achieve my goal.

  • Read frames from a h264 video in java

    19 octobre 2014, par Shashank Tulsyan

    I am making a tool which records the user’s screen.
    It records almost every activity of the user and saves it as a h264 video.

    I also make a note of the window names.
    Then I make charts out of this data, which tells me how much time the user (me) has spend on what activity. Now I want to take this one level further.
    I want to be able to see the filtered video as well.

    Let’s say, I know I have spend 4 hrs on Netbeans, I also want to see a video showing what all I did on netbeans.

    Some sample video files

    http://neembuu.com/testdir/sat_1413633155981_direct.mkv
    http://neembuu.com/testdir/fri_1413547843213_direct.264

    I am using x264 for encoding.

    These files might be corrupt. Because encoding stops when the user shutsdown the pc or close the program. There is no handling of abrupt program exit. EOF is not written properly. This is a design decision.

    Now the problem is, none of the libraries ( jcodec , h264j ) seem to be able to decode these files.
    I want individual frames.

    Problem with h264j

    • Doesn’t support seeking
    • Randomly doesn’t work for some files, although all files have been created using the same settings ( like the sample fri_1413547843213_direct.264 , h264j doesn’t work with it. )

    Problem with jcodec.

    • Can’t handle mkv
    • Not sure how to use with raw h264 streams (<<< help would be appreciated here, so far I couldn’t find a way to handle raw h264 streams in jcodec )
    • If I used the jcodec’s MP4 muxer ( org.jcodec.samples.mux.AVCMP4Mux ) it does generate a mp4 but it is not able to read the same mp4 which it only generated
    • JCodec handles externally generated mp4 files pretty well. Can seek to any random frame and renders the frame BufferedImage beautifully, but it seems I don’t have my videos in a format which jcodec can handle.

    The encoding settings which I am using.

    x264 - --keyint 240 --sar 1:1 --output "destinationFile" --stitchable --fps 1/1 --input-res 1280x800 --input-csp rgb

    Any tip/advice. How can I make this work ?
    Thanks :D
