Android-video-trimmer

Helps to trim local videos with many customizations on Android applications using exoplayer2 and FFmpeg Demo app.

How to use

For a working implementation, please have a look at the Sample Project

1. Include the library as local library project.

• Add the dependency to your app build.gradle file
• Take a look at light weight version of this library Android-video-trimmer-litr

dependencies {
   implementation 'com.github.a914-gowtham:android-video-trimmer:1.7.3'
}

• Add to project's root build.gradle file:

allprojects {
	repositories {
		maven { url 'https://jitpack.io' }
	}
}

2. Create a global variable for ActivityResultLauncher

    //Java
    ActivityResultLauncher<Intent> startForResult = registerForActivityResult(
            new ActivityResultContracts.StartActivityForResult(),
            result -> {
                if (result.getResultCode() == Activity.RESULT_OK &&
                        result.getData() != null) {
                    Uri uri = Uri.parse(TrimVideo.getTrimmedVideoPath(result.getData()));
                    Log.d(TAG, "Trimmed path:: " + uri);
                   
                } else
                    LogMessage.v("videoTrimResultLauncher data is null");
            });

    //Kotlin
    val startForResult = registerForActivityResult(ActivityResultContracts.StartActivityForResult()) { 
    result: ActivityResult ->
        if (result.resultCode == Activity.RESULT_OK &&
                        result.getData() != null) {
                Uri uri = Uri.parse(TrimVideo.getTrimmedVideoPath(result.getData()))
                Log.d(TAG, "Trimmed path:: " + uri)
         }else 
          	LogMessage.v("videoTrimResultLauncher data is null");
    }   

3. Add the code for opening Trim Activity.

TrimVideo.activity(String.valueOf(videoUri))
//        .setCompressOption(new CompressOption()) //empty constructor for default compress option
          .setHideSeekBar(true)
          .start(this,startForResult);

Customization

Video Compress:

.setCompressOption(new CompressOption(frameRate,bitRate,width,height))  //pass empty constructor for default compressoption

• FrameRate Recommeded frameRate is 30
• BitRate Bitrate Can be between 150k to 1000k or 1M to 10M.Lower bitrate can reduce the quality and size of the video. Use 1M for better quality output
• Width Width of the video output video.
• Height Height of the video output video.Use TrimmerUtils.getVideoWidthHeight(this,Uri.parse(videoUri)); method to get the width and height of the video

1. No need to use accurateCut while using video compressOption
2. Video compressing process will take more time

.setCompressOption(new CompressOption(30,"1M",460,320))
//You could divide the width and height by 2. when try to compress a large resolution videos ex:Taken from camera
/*int[] wAndh=TrimmerUtils.getVideoWidthHeight(this,Uri.parse(videoUri));
    int width=wAndh[0];
    int height=wAndh[1];
    if(wAndh[0]>800){
      width/=2;
      width/=2;
     .setCompressOption(new CompressOption(30,"1M",width,height))   
     }else
     .setCompressOption(new CompressOption(30,"400k",width,height))   
   */

Video Trim Accuracy:

.setAccurateCut(true) //default value is false 

1. AccurateCut false makes video trimming faster and less accuracy(approx. 1-3secs)
2. AccurateCut true makes video trimming slower and high accuracy

Hide Player Seekbar:

.setHideSeekBar(true) //default value is false 

Custom TrimTypes

TrimType Default:

TrimVideo.activity(videoUri)
          .start(this,startForResult);

TrimType Fixed Duration:

TrimVideo.activity(videoUri)
          .setTrimType(TrimType.FIXED_DURATION)
          .setFixedDuration(30) //seconds
          .start(this,startForResult);

TrimType Minimum Duration:

TrimVideo.activity(videoUri)
          .setTrimType(TrimType.MIN_DURATION)
          .setMinDuration(30) //seconds
          .start(this,startForResult);

TrimType Min-Max Duration:

TrimVideo.activity(videoUri)
          .setTrimType(TrimType.MIN_MAX_DURATION)
          .setMinToMax(10, 30)  //seconds
          .start(this,startForResult);
