Instance Attribute Details
- (AVAssetResourceLoader) resourceLoader (readonly)
The resource loader associated with the asset. (read-only) During loading, the resource loader object may be asked to assist in the loading of a resource. For example, a resource that requires decryption might result in the resource loader being asked to provide the appropriate decryption keys. You can assign a delegate object to the resource loader object and use your delegate to intercept these requests and provide an appropriate response.
- (NSURL) URL (readonly)
The URL with which the asset was initialized. (read-only)
Class Method Details
+ (Array) audiovisualMIMETypes
Returns an array of the MIME types the AVURLAsset class understands.
+ (Array) audiovisualTypes
Returns an array of the file types the AVURLAsset class understands.
+ (Boolean) isPlayableExtendedMIMEType(extendedMIMEType)
Returns a Boolean value that indicates whether the asset is playable with the given codec(s) and container type.
+ (AVURLAsset) URLAssetWithURL(URL, options:options)
Returns an asset for inspection of a resource referenced by a given URL.
Instance Method Details
- (AVAssetTrack) compatibleTrackForCompositionTrack(compositionTrack)
Returns an asset track from which any time range can be inserted into a given composition track. You insert the track into using insertTimeRange:ofTrack:atTime:error: (AVMutableCompositionTrack). This method is the logical complement of mutableTrackCompatibleWithTrack:.
- (Object) initWithURL(URL, options:options)
Initializes an asset for inspection of a resource referenced by a given URL.
