Downloaded content is not playing in NYT360Video player

 I'm using NYT360Video to play 360 content. But I'm facing problem while playing downloaded 360 content. Downloaded content is not playing and only audio is coming. We are using Apple FailPlay Streaming download technique. Does anyone gone through this kind of issue, or any suggestions ?
