QuickTime SDK 简介

 

Quicktime是Apple公司的多媒体编解码器,现在最新版是6.5.  编解码的文件格式以mov结尾. Quicktime SDK提供了2500多个编程接口,并且实现了MAC OS和windwos平台的兼容.QT SDK的结构与其他(如windwos media sdk)不同,以time为主线,来检索和编排媒体数据.当然,QT SDK也能够转换time与Frame之间的比例,获取每个video frame或audio sample的数据.

 

QT SDK主要包括一下几个部分或工具集合:

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.)

 

Quicktime 数据存储方式:

 

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