Hello,I am a developer of IOS：
when I switch video url to change TV program,the problem occurs frequently,I have confused about this for a long time and I don't know what to do,this is my code,very simple:
when I switch the video url，I create a new VLCMedia giving to player.media

NSURL *url=[NSURL URLWithString:staticUrl];

VLCMedia *media=[[VLCMedia alloc]initWithURL:url];

[media addOptions:mediaOptions];

[player stop];
player.media=media;

[player play];

I want to ask how to solve this problem by myself or next version of IOS will fix this problem? Thanks!!!
