QuickTime SDK 簡介

 

 

Quicktime是Apple公司的多媒體轉碼器，現在最新版是7.3。 編解碼的檔案格式以mov結尾。 Quicktime SDK提供了2500多個編程介面，並且實現了MAC OS和windwos平台的相容。QT SDK的結構與其他(如windwos media sdk)不同，以time為主線,來檢索和編排媒體資料。當然，QT SDK也能夠轉換time與Frame之間的比例，擷取每個video frame或audio sample的資料。目前最新的SDK 7.3 for windows

 

 

 

QT SDK主要包括一下幾個部分或工具集合:

1, tool sets:

1> movie toolbox:  is used to initialize QuickTime; open, play, edit, and save movies; and manipulate time-based media.

2> the Image Compression Manager:  is a device-independent and driver-independent means of compressing and decompressing image data.

3> the sequence grabber: is a framework for components that capture and record samples from real-time sources, such as video cards or audio inputs.

4> QuickTime streaming API: send and receive real-time streams using standard protocols such as RTP and RTSP.

5> QuickTime VR,

6> sprite toolbox,

7> wired movies API,

2， components

1> Movie controller components :   used to play movies and can provide a standard user interface.

2> Media handler components :  handle a particular type of media data, such as video, sound, Flash,or text

.3> Data handler components:  access data from a particular kind of data source, such as local files,URLs, pointers, or handles

4> Image compressor components :compress or decompress image data.

5> Image compression dialog components : let the user specify the parameters for compression operations.

6> Video digitizer components : are used to control video digitization by external devices such as video capture cards.

7> Movie data-exchange components (also known as movie import and movie export components): move different types of data into and out of QuickTime movies. QuickTime can play any type of  media file for which it has an importer or create any type for which it has an exporter.

8> Video output components: convert the visual output of QuickTime movies into video streams for devices other than displays.

9> Graphics import and export components: provide a single API that lets you work with a wide variety of image file formats.

10> Music components : process and synthesize MIDI-like music tracks in QuickTime movies.

11> Effects and transitions components : implement visual filters, effects, and transitions. (Effects components are implemented as a special type of image compressor component.)

 

 

 

 

由上可見QT功能的強大，不僅支援許多video,audio，而且支援image,image sequence .不僅支援encoding,decoding,還有grab.

 

 

 

 

Quicktime 資料存放區方式:

 

 

 mov file--->movie--->tracks(time, media,)--->samples
