• is there a way to auto trim parts of my video when a specefic color or text shows up on those parts

  10 novembre 2022, par Yousif K Al Ameen 1

  I play a game and record it, but unfortunately many parts of that recording is when my internet connection gets lost for several seconds. During that period it only shows a text that says "connection lost". Then the game resumes normally in few seconds after the connection is back.
Is there a software or a way that allows me to auto trim these connection lost periods from my viedeo ? Please help I need to trim a lot of these periods so that I can post cool gaming videos online without the "connection lost" scenes included.

  


  I tried searching on youtube and found some ffmpeg, python, and opencv methods but none of which is suitabal or easy to apply for my situation

  


• FFmpeg RTSP Recording : Video Timestamp Does not Match With Recorded MP4 File Timestamp [closed]

  26 avril 2024, par lastpeony4

  I'm currently testing by streaming a 30 fps example flv video using a local Happy-Time RTSP server.

  


  This is the flv file i am streaming with RTSP :

  


  

  


  I recorded the video with below ffmpeg command :

  


  ffmpeg -i rtsp://127.0.0.1:6555/test30fps.flv -c copy test30fps.mp4


  


  The resulting video appears visually satisfactory, yet there's a discrepancy between the displayed time on the video and the actual duration of the video file. Although the MP4 file duration is correct (endRecordingTimeMs-startRecordingTimeMs= mp4 file duration), the time displayed within the video does not synchronize precisely with the file's time. Notably, this disparity escalates as the video progresses.

  


  I anticipate the time text overlaid on the video and the file's time to align seamlessly. However, a few seconds of divergence are noticeable, gradually expanding over the video's duration.

  


  

  


  Why does this occur and is there any way to fix this ?

  


• 'Source code does not match byte code' Android Studio

  26 août 2020, par Connoe

  I'm developing an Android video editing app using FFmpeg libraries in Android Studio version 4.01. When I try to debug, the debugger steps into the decompiler and flashes, 'Source code does not match byte code' across multiple steps through the decompiled code. The debugger also seems to be jumping around the decompiled code semi-randomly, for example : here, where logSlowDispatch is false but the debugger steps into the contents of the if statement anyway without checking and flashes 'Source code does not match byte code'. I've looked at alot of posts about this problem and have tried many of the suggested solutions from invalidate cache/restart to a fresh install of Android Studio to no avail. I've read that redundant or outdated gradle dependencies might have something to do with this, but removing some of these dependencies hasn't helped :

  


  apply plugin: 'com.android.application'

android {
    compileSdkVersion 29
    defaultConfig {
        applicationId "com.example.capstoneapplication"
        minSdkVersion 21
        targetSdkVersion 29
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        ndkVersion "21.3.6528147"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])

    implementation 'com.android.support.constraint:constraint-layout:2.0.0'

    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'

    implementation 'com.writingminds:FFmpegAndroid:0.3.2'

    implementation 'org.florescu.android.rangeseekbar:rangeseekbar-library:0.3.0'

    implementation 'com.intuit.sdp:sdp-android:1.0.6'
}


  


  My code seems to be running properly and executing the ffmpeg command on the desired video between these jumps to the decompiler, but the video does not save. Here is a snippet from the java class that might be causing this :

  


      @Override
    public boolean onOptionsItemSelected(MenuItem menuItem){
        if(menuItem.getItemId()==R.id.trim){
            final AlertDialog.Builder alertDialog = new AlertDialog.Builder(com.example.capstoneapplication.VideoTrimmer.this);

            LinearLayout linLay = new LinearLayout(com.example.capstoneapplication.VideoTrimmer.this);
            linLay.setOrientation(LinearLayout.VERTICAL);
            LinearLayout.LayoutParams layPar = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
            layPar.setMargins(50, 0, 50, 100 );
            final EditText input = new EditText(com.example.capstoneapplication.VideoTrimmer.this);
            input.setLayoutParams(layPar);
            input.setGravity(Gravity.TOP|Gravity.START);
            input.setInputType(InputType.TYPE_TEXT_FLAG_CAP_SENTENCES);
            linLay.addView(input,layPar);

            alertDialog.setMessage("Enter Video Name");
            alertDialog.setTitle("Change Video Name");
            alertDialog.setView(linLay);
            alertDialog.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    dialog.dismiss();
                }
            });
            alertDialog.setPositiveButton("Submit", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    fileName = input.getText().toString();

                    try {
                        snipVideo(videoDurBar.getAbsoluteMinValue().intValue(), videoDurBar.getSelectedMaxValue().intValue(), fileName);
                    } catch ( FFmpegNotSupportedException e) {
                        e.printStackTrace();
                    }


                }
            });
            alertDialog.show();
        }
        return super.onOptionsItemSelected(menuItem);
    }

    private void snipVideo( int min, int max, String fileName) throws FFmpegNotSupportedException {

        File destFolder = new File("storage/emulated/0" + "/EditingApeSnippedVideos");
        if(!destFolder.exists()){
            destFolder.mkdir();
        }
        String fileExtension = ".mp4";
        destination = new File(destFolder, fileName + fileExtension);
        inputVideoPath = getPathFromUri(getApplicationContext(),uri);


        command = new String[]{"-ss", "" + min/1000 , "-y", "-i", inputVideoPath, "-t", ""+ (max-min)/1000 ,"-vcodec", "mpeg4", "-b:v","2097152","-b:a", "48000", "-ac","2","-ar","22050", destination.getAbsolutePath()};

        //testing command
        //command = new String []{"-y", "-i", inputVideoPath, "-ss", "00:00:02" , "-to", "00:00:03", "-c", "copy", destination.getAbsolutePath()};
        final FFmpeg ff = FFmpeg.getInstance(this);
        ff.loadBinary(new FFmpegLoadBinaryResponseHandler() {

            @Override
            public void onStart() {

                Log.i("VideoTrimmer","onStart");
            }

            @Override
            public void onFinish() {
                Log.i("VideoTrimmer","onFinish");
            }

            @Override
            public void onFailure() {
                Log.i("VideoTrimmer","onFailure");
            }

            @Override
            public void onSuccess() {
                Log.i("VideoTrimmer","Success");
                try {
                    ff.execute(command, new ExecuteBinaryResponseHandler());
                } catch (FFmpegCommandAlreadyRunningException e) {
                    Log.i("VideoTrimmer","FFmpegAlreadyRunning Exception");

                }
            }
        });
    }


  


  Has anyone found a solution to this debugger issue ?
