Helps to trim local videos with many customizations on Android applications using exoplayer2 and FFmpeg Demo app
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.gradlefile - Take a look at light weight version of this library Android-video-trimmer-litr
// 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.gradlefile:
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))
.setHideSeekBar(true)
.start(this,startForResult);TrimVideo.activity(String.valueOf(videoUri))
.setHideSeekBar(true)
.start(this,startForResult);- Fastest processing, No losses in quality((no compression), will be low accurate(2-3 secs)
TrimVideo.activity(String.valueOf(videoUri))
.setAccurateCut(true)
.setHideSeekBar(true)
.start(this,startForResult);- Faster processing, No losses in quality(no compression), accurate trimming.
.setCompressOption(new CompressOption(frameRate,bitRate,width,height)) //pass empty constructor for default compressoptionFrameRateRecommeded frameRate is 30BitRateBitrate Can be between 150k to 1000k or 1M to 10M.Lower bitrate can reduce the quality and size of the video. Use 1M for decent quality outputWidthWidth of the video output video.HeightHeight of the video output video.UseTrimmerUtils.getVideoWidthHeight(this,Uri.parse(videoUri));method to get the width and height of the video
- Video compressing process will take more time and duration will be accurate
TrimVideo.activity(String.valueOf(videoUri))
.setCompressOption(new CompressOption(30,"1M",460,320)) //pass empty constructor for default compress values
.setHideSeekBar(true)
.start(this,startForResult);
//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))
*/.setHideSeekBar(true) //default value is false TrimVideo.activity(videoUri)
.start(this,startForResult);TrimVideo.activity(videoUri)
.setTrimType(TrimType.FIXED_DURATION)
.setFixedDuration(30) //seconds
.start(this,startForResult);TrimVideo.activity(videoUri)
.setTrimType(TrimType.MIN_DURATION)
.setMinDuration(30) //seconds
.start(this,startForResult);TrimVideo.activity(videoUri)
.setTrimType(TrimType.MIN_MAX_DURATION)
.setMinToMax(10, 30) //seconds
.start(this,startForResult);-dontwarn com.gowtham.library**
