How to order video on the educational resource network vod?
Compared with traditional video formats such as AVI and MPEG, streaming media adopts streaming transmission system, so users can watch the video without waiting for the whole file to be downloaded, and only after a few seconds or more startup delay. In view of all aspects of streaming media, I made a summary for you, hoping to help you make good use of this excellent technology. The connection protocols of these streaming media files are not common HTTP or FTP, so they cannot be downloaded by conventional software such as FlashGet and Netants. In fact, this situation is normal, because the protocols followed by streaming media have not been unified, and Microsoft's MMS and realNetworks' RSTP are still competing.

StreamBox VCR: the main force of streaming media file download

Specialty: downloading streaming media files such as ASF, RM, WMA and RA. Take them to the local area and play them.

File size: 1865KB

This software can download streaming media files such as ASF, RM, WMA, RA, etc. and play them locally, which will not affect the viewing because of the slow network speed. Of course, the biggest advantage is that you can save those "streaming" programs that you can't save. When you run StreamBox VCR for the first time, a "Set Account" dialog box will pop up, and you need to fill in the name, email address and password used for registration. Enter the main interface of the software through it. Note: you must fill in the form when you use it for the first time, but don't worry, this program will not reveal privacy. Please wait patiently and don't be prompted again (unless the registry key has been deleted).

StreamBox VCR can analyze the real download links of streaming media files behind RSTP and MMS addresses, and finally download the files to the local hard disk. At present, StreamBox VCR supports downloading streaming media files in RM(Real Media), ASX (Microsoft Streaming Media File), SMIL (Synchronized Multimedia Integration Language, Real Media Content), PLS(MP3 Streaming Media File), MOV(Quicktime File) and other formats, and also supports breakpoint continuation!

Streambox VCR not only supports on-demand streaming media programs, but also supports live streaming media programs, both of which can be downloaded at the same time! Because of its unique analysis technology, ASF files hidden behind ASX and RM files hidden behind SMIL files can be found and downloaded.

The interface of StreamBox VCR is very refreshing, but it can't be started in real time in the browser because there is no seamless link with IE browser, and there is no option about it in the right-click menu. Apart from this defect, StreamBox VCR is almost perfect in other aspects. When using StreamBox VCR, the address of streaming media should be obtained first. Many friends don't even know how to do this step. It's actually quite simple. Right-click the previous link in the browser to start RealPlayer or Media Player, and then select the copy shortcut (as shown in figure 1). Then we can see many icons in the StreamBox VCR interface, and their specific meanings are shown in Figure 2. After clicking Add, StreamBox VCR will automatically use the contents of the clipboard as the download address.

Remind everyone that if you use broadband network, you must set the network bandwidth correctly, otherwise the download speed of StreamBox VCR will be greatly reduced. When we add a new project, the links in the tab bar are used to set the network bandwidth (as shown in Figure 3). With these simple steps, StreamBox VCR will work hard for us, and all the status will be clear at a glance.

Auxiliary tool 1:ASF recorder

Specialty: a tool specially used to download streaming media files in ASF and WMV formats.

File size: 368KB (including source code)

ASFRecorder (the running interface is shown in Figure 4) can not only download ASF back, but also support ASX file, the index format of ASF file, find out the real stream hidden in ASX, and even set up a proxy. It is very powerful and easy to use. Just select Open URL under the File menu and enter the address of the streaming media program, and you can return to the main interface and press the triangle symbol to start downloading. ASFRecorder uses unique technology to simulate normal playback, and then reassembles the streaming media data modulated by the streaming media server into files. So its appearance has seriously threatened the copyright of streaming media files such as ASF. After Microsoft put pressure on the software author, the development of this software has stopped. Fortunately, the author disclosed the source code of this software.

ASFRecorder's interface is not as good as StreamBox VCR, but because of its special working principle, it can often download streaming media that StreamBox VCR cannot explore.

Auxiliary tool 2: SDP

Specialties: In the case that Streambox VCR and ASFRecorder are unsuccessful in downloading, trying this software may make you feel that the future is bright.

File size: 2474KB

The streaming download project is the latest streaming media software launched by ASF/WMV. Its biggest feature is that it can find the real download address and download streaming media in the most hidden way. Unfortunately, the streaming download project does not support multi-thread download and continuous transmission. If you can bear it without multithreading download, then it is really uncomfortable without the continuation function. After all, hundreds of megabytes of streaming media files will inevitably make mistakes in the transmission process.
