This paper introduces how to use Visual (C+ +) to edit ASF files and realize multimedia synchronizing play, which is based on the deeply parse of the ASF file inner structure.
The method being adopted is that using Visual C++ 6.0 to explore an ASF editing tool ,and using it to edit ASF file to realize multimedia synchronizing play ,which is based on the deeply parse of the ASF file inner structure and the script command object has been added into the ASF file successfully.
Our work is aimed to seek a method to realize VOD on a LAN by the streaming media technology in terms of RM and ASF file format. An actual VOD sample and the program code access to the video database are given.
This article first discusses the technology of COM module and the work principle of DirectShow technology, emphasizes on how to use above technology to develop the captions superposed filter used in the courseware making platform, then introduces the technology of ASF the media stream technology, discusses the ASF file format and the ASF media coding technology with emphasis, proposes an applied scheme of ASF in the courseware making platform.
At present the high- speed and wide- band web has not been popularized yet,especially in western China. The VOD by making use of the modem is hardly to get a satisfied effect although there are some video clips broadcasting on the web. In some enterprises and universities, the file downloading rate on LANs may actually be increased from hundreds Kbps to 1 Mbps or so, which makes it possible to realize VOD on such a LAN by the streaming media technology. Our work is aimed to seek a method to realize VO...
The high-speed and wide-band web is not popular at present. The VOD using modem is hardly to get a satisfactory effect although there are some video clips to broadcast on the web. But the file downloading rate on LANs of some businesses, institution and universities may actually get from hundreds MB to 1 MB or so, which makes it possible to realize VOD on such a LAN using the streaming media technology. Our work is aimed to seek a method to realize VOD on a LAN using the streaming media technology in ...
The research aim of this paper is through editing ASF file realize the synchronization of multimedia. The method being adopted is that using Visual C++ 6.0 to explore an ASF editing tool ,and using it to edit ASF file to realize multimedia synchronizing play ,which is based on the deeply parse of the ASF file inner structure and the script command object has been added into the ASF file successfully.Testified by the practice ,the method is an effect and ...
