问题
I currently work at a cable TV provider in Brazil which requires DVB Bitmap for some of its assets. I've searched quite alot on Google and Stackoverflow and haven't found any denial or confirmation about this.
Does AVPlayer support DVB Bitmap subtitles? If not, which subtitle types does it support?
