Android App to Append Mp4 Videos or Merge Audio files with video files on your Android device. Code is written in kotlin and supports RxJava2.
It has two basic features:
- Append multiple Mp4 Videos into single video file
- Mp4 Video Audio Overlay (Mux/Merge)
Note: Only Mp4 and AAC format files are supported.
Append Usage:
val videoPaths = arrayListOf<String>(video.path, video2.path)
val appendExample = AppendExample(videoPaths)
//This will append video files together in a sequence they were added. Output will be a single video file.
appendExample.append()
.subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())
.subscribeBy(
onNext = {
if (TextUtils.isEmpty(it)) {
showToast(getString(R.string.message_error))
} else {
Log.i(TAG, "Output Path: $it")
showToast(getString(R.string.message_appended) + " " + it)
}
},
onError = {
it.printStackTrace()
},
onComplete = {}
)
Merge Usage
val mergeExample = MergeExample(video.path, audio2.path)
//This will merge audio and video files together in a single video file.
mergeExample.merge()
.subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())
.subscribeBy(
onNext = {
if (TextUtils.isEmpty(it)) {
showToast(getString(R.string.message_error))
} else {
Log.i(TAG, "Output Path: $it")
