Playing a video from res/raw on Android Wear

More specific: I am trying to load a video from res/raw with jcodec's FrameGrab.

FrameGrab requires a SeekableBiteChannel, so a File will work.

How can I get a video file from assets as a File?

I cannot put the video on the sd-card or anything similar, I am developing for Android Wear.

EDIT:

String videoPath = "android.resource://" + getPackageName() + "/" + R.raw.hyperlapse2;
mVideoTestUri = Uri.parse(videoPath);
Log.d("VideoPlayer", "Video uri is " + mVideoTestUri);
File file = new File(videoPath);
Log.d("VideoPlayer", "Video file is " + file+", "+file.getName()+", "+file.getAbsolutePath()+", "+file.length());

Finally I made it work. I don't know if this is something Android Wear specific or a bug, but it turns out that

String path = "android.resource://" + getPackageName() + "/" + R.raw.video_file;
File file = new File(path);

does not give access to the file on Android Wear devices.

Instead one has to convert the file into a temp file first:

InputStream ins = MainActivityBackup.this.getResources().openRawResource (R.raw.hyperlapse2);
File tmpFile = null;
OutputStream output;

try {
    tmpFile = File.createTempFile("video","mov");
    output = new FileOutputStream(tmpFile);

    final byte[] buffer = new byte[102400];
    int read;

    while ((read = ins.read(buffer)) != -1) {
        output.write(buffer, 0, read);
    }
    output.flush();
    output.close();
    ins.close();
} catch (IOException e) {
    e.printStackTrace();
}

And then it can be loaded into a videoView

mVideoView.setVideoPath(tmpFile.getPath());

Provided you are using your own video decoder or a library like ffmpeg or vitamio, since Android Wear does not support native video playback yet.

Place the video in the resource directory under a folder called raw.

String path = "android.resource://" + getPackageName() + "/" + R.raw.video_file;
File file = new File(path);

VideoView view = (VideoView)findViewById(R.id.videoView);
view.setVideoURI(Uri.parse(path));
view.start();
