Preventing no-audio AVPlayer from pausing background audio

I understand that based on AVAudioSession category AVPlayer will pause background audio currently played by other app when starting its playback. I wonder if this is the expected behavior regardless of the type item/content being played?

I'm asking as in my case showing video with no sound. The video files contain no audio track. AVPlayer itself is also set to muted. It just a little weird to me that I still have to change to AVAudioSession category even though I do not produce audio. So I want to know if that is by design or if there is something that I miss. For example, could I set up AVPlayer with no audio session so that it knows not to worry about audio or something like that.

No. Just set the audio category to "Ambient" so that it doesn't step on any other audio:

AVAudioSession *session = [AVAudioSession sharedInstance];
if (session) {
    NSError *setCategoryError = nil;
    BOOL success = [session setCategory:AVAudioSessionCategoryAmbient error:&setCategoryError];
    if (success) {
        NSError *activationError = nil;
        [session setActive:YES error:&activationError];
    } else {
        NSLog(@"Failed to set music category to ambient. May interrupt other audio.");
    }
}
