- Video can be trimmed/shortened and played on the same screen
- Video can be trimmed by selecting the starting point and ending point, and it will display the video size and video duration based on the selected position
- Seekbar moves as per selected video for trimming
- After trimming, trimmed video can be played automatically and can be shared on social media
- User can record video from camera or select video from gallery
- Set the selected video in the trimming screen
- Trim the video by dragging starting point and end point
- View trimmed video on the trimming screen
- Save video, it will automatically play in next screen
- Share the video
- Whenever it is required to crop thr video, this code can help you
- Whenever you are having a limiation of video recording such as allow users to record video for 1 min, this code can help you
- Android 4.1+
- When you are developing a Social or standalone video sharing app, this code will help you to provide functinality of trimming video and sharing video with user friendly operations.
Step 1: Send Video URL To Video Trimming class
if (mVideoTrimmer != null) {
mVideoTrimmer.setMaxDuration(60);
mVideoTrimmer.setOnTrimVideoListener(this);
mVideoTrimmer.setOnK4LVideoListener(this);
//mVideoTrimmer.setDestinationPath("/storage/emulated/0/DCIM/CameraCustom/");
mVideoTrimmer.setVideoURI(Uri.parse(path));
mVideoTrimmer.setVideoInformationVisibility(true);
}
Step 2: Initializtion of trimming views as we have declared in xml files
LayoutInflater.from(context).inflate(R.layout.view_time_line, this, true);
mHolderTopView = ((SeekBar) findViewById(R.id.handlerTop));
mVideoProgressIndicator = ((ProgressBarView) findViewById(R.id.timeVideoView));
mRangeSeekBarView = ((RangeSeekBarView) findViewById(R.id.timeLineBar));
mLinearVideo = ((RelativeLayout) findViewById(R.id.layout_surface_view));
mVideoView = ((VideoView) findViewById(R.id.video_loader));
mPlayView = ((ImageView) findViewById(R.id.icon_video_play));
mTimeInfoContainer = findViewById(R.id.timeText);
mTextSize = ((TextView) findViewById(R.id.textSize));
mTextTimeFrame = ((TextView) findViewById(R.id.textTimeSelection));
mTextTime = ((TextView) findViewById(R.id.textTime));
mTimeLineView = ((TimeLineView) findViewById(R.id.timeLineView));
setUpListeners();
setUpMargins();
Step 3: To prepare video as it is trimmed by user onVideoPrepared() method is used
private void onVideoPrepared(@NonNull MediaPlayer mp) {
// Adjust the size of the video
// so it fits on the screen
int videoWidth = mp.getVideoWidth();
int videoHeight = mp.getVideoHeight();
float videoProportion = (float) videoWidth / (float) videoHeight;
int screenWidth = mLinearVideo.getWidth();
int screenHeight = mLinearVideo.getHeight();
float screenProportion = (float) screenWidth / (float) screenHeight;
ViewGroup.LayoutParams lp = mVideoView.getLayoutParams();
if (videoProportion > screenProportion) {
lp.width = screenWidth;
lp.height = (int) ((float) screenWidth / videoProportion);
} else {
lp.width = (int) (videoProportion * (float) screenHeight);
lp.height = screenHeight;
}
mVideoView.setLayoutParams(lp);
mPlayView.setVisibility(View.VISIBLE);
mDuration = mVideoView.getDuration();
setSeekBarPosition();
setTimeFrames();
setTimeVideo(0);
if (mOnK4LVideoListener != null) {
mOnK4LVideoListener.onVideoPrepared();
}
}
Step 4: Give position for seekbar fom start to end
private void setSeekBarPosition() {
if (mDuration >= mMaxDuration) {
mStartPosition = mDuration / 2 - mMaxDuration / 2;
mEndPosition = mDuration / 2 + mMaxDuration / 2;
mRangeSeekBarView.setThumbValue(0, (mStartPosition * 100) / mDuration);
mRangeSeekBarView.setThumbValue(1, (mEndPosition * 100) / mDuration);
} else {
mStartPosition = 0;
mEndPosition = mDuration;
}
setProgressBarPosition(mStartPosition);
mVideoView.seekTo(mStartPosition);
mTimeVideo = mDuration;
mRangeSeekBarView.initMaxWidth();
}
Step 5: To give permission for seekbar to start moving from start to end, setSeekBarPosition() is used
private void setSeekBarPosition() {
if (mDuration >= mMaxDuration) {
mStartPosition = mDuration / 2 - mMaxDuration / 2;
mEndPosition = mDuration / 2 + mMaxDuration / 2;
mRangeSeekBarView.setThumbValue(0, (mStartPosition * 100) / mDuration);
mRangeSeekBarView.setThumbValue(1, (mEndPosition * 100) / mDuration);
} else {
mStartPosition = 0;
mEndPosition = mDuration;
}
setProgressBarPosition(mStartPosition);
mVideoView.seekTo(mStartPosition);
mTimeVideo = mDuration;
mRangeSeekBarView.initMaxWidth();
}
Step 6: To synchronize video frames with time setTimeFrames() is used
private void setTimeFrames() {
String seconds = getContext().getString(R.string.short_seconds);
mTextTimeFrame.setText(String.format("%s %s - %s %s", stringForTime(mStartPosition), seconds, stringForTime(mEndPosition), seconds));
}
Step 7: Set Start and end point of that video using onSeekThumbs() method
private void onSeekThumbs(int index, float value) {
switch (index) {
case Thumb.LEFT: {
mStartPosition = (int) ((mDuration * value) / 100L);
mVideoView.seekTo(mStartPosition);
break;
}
case Thumb.RIGHT: {
mEndPosition = (int) ((mDuration * value) / 100L);
break;
}
}
setProgressBarPosition(mStartPosition);
setTimeFrames();
mTimeVideo = mEndPosition - mStartPosition;
}
We’d be really happy if you sent us links to your projects where you use our component. Just send an email to [email protected] and do let us know if you have any questions or suggestion regarding video trimming in Android.
P.S. We’re going to publish more awesomeness examples on third party libraries, coding standards, plugins etc, in all the technology. Stay tuned!
