Create(VTDecompressionSession+VTDecompressionOutputCallback, CMVideoFormatDescription, VTVideoDecoderSpecification, CVPixelBufferAttributes)

public static VideoToolbox.VTDecompressionSession Create (VideoToolbox.VTDecompressionSession.VTDecompressionOutputCallback outputCallback, CoreMedia.CMVideoFormatDescription formatDescription, VideoToolbox.VTVideoDecoderSpecification decoderSpecification, CoreVideo.CVPixelBufferAttributes destinationImageBufferAttributes);
static member Create : VideoToolbox.VTDecompressionSession.VTDecompressionOutputCallback * CoreMedia.CMVideoFormatDescription * VideoToolbox.VTVideoDecoderSpecification * CoreVideo.CVPixelBufferAttributes -> VideoToolbox.VTDecompressionSession

参数

formatDescription
CMVideoFormatDescription
decoderSpecification
VTVideoDecoderSpecification
destinationImageBufferAttributes
CVPixelBufferAttributes

返回

适用于

Create(VTDecompressionSession+VTDecompressionOutputCallback, CMVideoFormatDescription, VTVideoDecoderSpecification, NSDictionary)

注意

This overload requires that the provided compressionOutputCallback manually CFRetain the passed CMSampleBuffer, use Create(VTDecompressionOutputCallback,CMVideoFormatDescription,VTVideoDecoderSpecification,CVPixelBufferAttributes) variant instead which does not have that requirement.
