Android Extract Decode Encode Mux Audio

Question

I am trying to adapt the code found in ExtractDecodeEditEncodeMuxTest.java in order to extract audio and video from a mp4 recorded via Cordova\'s device.capture.captureVideo

Answer 1

Turns out the above code works fine - as long as you're not trying to mux the same file you're extracting, at the same time.

:-)

I had a previous version of this that extracted, then muxed tracks to the same file, and forgot to change that in this version.

This little method saved the day lol.

private String getMuxedAssetPath() {
    String muxedAssetPath = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM) + "/" + CAMERA_DIRECTORY + "/muxedAudioVideo.mp4";

    File file = new File(muxedAssetPath);
    if (!file.exists()) {
        try {
            file.createNewFile();
        } catch (IOException e) {
            e.printStackTrace();
            muxedAssetPath = null;
        }
    }

    return muxedAssetPath;
}
