you can use statement check sound of video 

if([[songasset trackswithmediatype:avmediatypeaudio] firstobject]==null) {     nslog(@"sound not present"); } else {     nslog(@"sound present");     //you initalise things     avassettrack *sourceaudiotrack = [[songasset trackswithmediatype:avmediatypeaudio] objectatindex:0];  }
