appendImmediately

TypeScript

appendImmediately(pixelBuffer: _CoreVideo_CVReadOnlyPixelBuffer, presentationTime: _CoreMedia_CMTime): boolean

Swift declaration

func appendImmediately(_ pixelBuffer: CVReadOnlyPixelBuffer, with presentationTime: CMTime) throws -> Bool

Appends the pixel buffer synchronously if the input is ready for more media data. - Parameter pixelBuffer: The pixel buffer to be appended. - Parameter presentationTime: The presentation time for the pixel buffer to be appended. - Returns: Returns true if the append was successful, false if the input was not ready for more media data. - Throws: An error if the underlying writer failed.
