ANDROID: MoviePlayerGI does not stop reliably

[eighteight]

I play and stop the MoviePlayerGI repeatedly.

1. Start player -- everything seems fine.
2. Stop player -- everything is fine.
3. Start player -- the image is black (but I can hear the sound).
4. Stop player -- stop does not work (I hear the sound after attempted stop)
5. Start player === item 1 scenario, except that at this point I still hear the audio from the player started on 3.

This is how I start the player:

float AugmentedTheatreApp::playMovie(const fs::path &moviePath)
{
    try {
        mMovie = cinder::android::video::MovieGl::create( moviePath );
        mMovie->setVolume(mVolume);
        mMovie->setLoop(true);
        mMovie->play();
    }
    catch( ci::Exception &exc ) {
        console() << "Exception caught trying to load the movie from path: " << moviePath << ", what: " << exc.what() << std::endl;
        mMovie.reset();
    }
    
    mVideoTexture.reset();
    return mMovie->getDuration();
}

Stopping the movie player:

void AugmentedTheatreApp::stopMovie()
{
    if (mMovie) {
        mMovie->stop();
    }
    if (mVideoTexture)
        mVideoTexture.reset();
}

The console output

5. Same as 1.

@eighteight have you found a solution to this? I'm seeing weird behaviour as well. first play and stop works, but after that play has no effect.

@gaborpapp Sorry, I don't remember, and I am not at my computer. Let me get back to you in a few days.

I found that you cannot call start() after stop() with Android MediaPlayer, you would need prepare() between the two. I'm using pause() now as a workaround.
