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

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:1.7.0'
}

Add to project's root build.gradle file:

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

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");
    }

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

No need to use accurateCut while using video compressOption
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

AccurateCut false makes video trimming faster and less accuracy(approx. 1-3secs)
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);
