Starting from 1.8.0 this library is using media3 for media transcoding. Previously it was using ffmpeg which is deprecated now.

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

// replace x.y.z with latest available jitpack version
dependencies {
   implementation 'com.github.a914-gowtham:android-video-trimmer:x.y.z'
}

• 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))
          .setHideSeekBar(true)
          .disableCompression()   // to disable compression ui. enabled by default
          .start(this,startForResult);

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);

Proguard Rules

-dontwarn com.gowtham.library**
-keep class com.gowtham.library** { *; }
-keep interface com.gowtham.library** { *; }

Development roadmap:

1. Currently, compression only reduces the bitRate to reduce the file size. converting video to the selected resolution is in under development - DONE
2. Showing file size estimation in toolbar subtitle - to be worked
