Before finishing loading an
AVAsset instance, if its
content property is not
nil, set the value of this property to
true if it supports random access to arbitrary ranges of bytes of the resource.
If this property is not
true for resources that must be loaded incrementally, loading of the resource may fail. Such resources include anything that contains media data.
If byte range access is supported portions of the resource can be requested more than once.
