Function VTMultiPassStorageCreate

pub unsafe extern "C-unwind" fn VTMultiPassStorageCreate(
    allocator: Option<&CFAllocator>,
    file_url: Option<&CFURL>,

Available on crate features VTMultiPassStorage and objc2-core-media only.

Creates a VTMultiPassStorage object using a temporary file.

The returned VTMultiPassStorage object may be used to perform multi-pass encoding; see kVTCompressionPropertyKey_MultiPassStorage. Call CFRelease to release your retain on the created VTMultiPassStorage object when you are done with it.

Parameter fileURL: Specifies where to put the backing file for the VTMultiPassStorage object. If you pass NULL for fileURL, the video toolbox will pick a unique temporary file name.

Parameter timeRange: Gives a hint to the multi pass storage about valid time stamps for data.

Parameter options: If the file did not exist when the storage was created, the file will be deleted when the VTMultiPassStorage object is finalized, unless you set the kVTMultiPassStorageCreationOption_DoNotDelete option to kCFBooleanTrue in the options dictionary.
