# ohos-ffmpeg-java

## Introduction
This Project is Audio/Video Processor, It is a Java wrapper around an ffmpeg command line binary and sox command line binary for use in openharmony applications. For ease of developer use, we've included the FFMPEG and Sox binaries embedded in the project.

## Usage instructions
Sample code on how to Trim video with ffmpeg apis.
```java
        String input_video_file_path = ResUtil.getMediaInputFilePath(ctx, "samplevideo.mp4");
        String output_trimmed_file_path = "/storage/emulated/0/Android/data/org.ffmpeg.ohos.sample/files/Music/trimsamplevideo.mp4";
        try {
            Clip clip_trim = new Clip(input_video_file_path);
            clip_trim.startTime = "00:00:04";   //Starting time in second
            clip_trim.duration = 8; //Duration in seconds
            new FfmpegController(ctx, new File("/tmp")).trim(clip_trim, true, output_trimmed_file_path, new ShellUtils.ShellCallback() {
                @Override
                public void shellOut(String shellLine) {
                    Log.d(TAG, " shellOut shellLine=" + shellLine);
                }

                @Override
                public void processComplete(int exitValue) {
                    Log.i(TAG, " processComplete");
                }
            });
            return true;	//success
        } catch (Exception e) {
            Log.e(TAG, " Got Exception=" + e.getMessage());
            return false;	//failure
        }
```
Sample code to Mix two audio files with fading effect.
```java

 String input_audio_file_path1 = ResUtil.getMediaInputFilePath(ctx, "imperialmarch60.wav");
        String input_audio_file_path2 = ResUtil.getMediaInputFilePath(ctx, "pinkpanther60.wav");
        String output_audio_file_path = "/storage/emulated/0/Android/data/org.ffmpeg.ohos.sample/files/Music/mixedaudio.wav";
        try {
            SoxController soxc = new SoxController(ctx, null, new ShellUtils.ShellCallback() {
                @Override
                public void shellOut(String shellLine) {
                    Log.d(TAG, " shellOut shellLine=" + shellLine);
                }

                @Override
                public void processComplete(int exitValue) {
                    Log.i(TAG, " processComplete");
                }
            });
            new CrossfadeCat(soxc, input_audio_file_path1, input_audio_file_path2, 20, output_audio_file_path).start();
            return true;
        } catch (Exception e) {
            Log.e(TAG, " Got Exception=" + e.getMessage());
            return false;
        }	 
```

## Installation instruction
Solution 1.	For using ohos-ffmpeg-java module in sample app, include the below library dependency to generate hap/ohos-ffmpeg-java.har:
	Add the dependencies in entry/build.gradle as below:

    dependencies {
      implementation project(path: ':library')
    }

Solution 2. Using the ohos-ffmpeg-java library har, make sure to add ohos-ffmpeg-java.har file in the entry/libs folder and add the below dependency in build.gradle.
	Modify the dependencies in the entry/build.gradle file.

	dependencies {
		implementation fileTree(dir: 'libs', include: ['*.jar', '*.har'])
	}
