Discover a fatal weakness of the RM video file on the web page, that is, you must download all the RM files locally, then start playing, so that the web is open, and if you are not careful, Realone will prompt you to connect timeout. By testing in the LAN, you can find a 20m more video file, you can also be barely connect, about twenty seconds, will be completely downloaded to the local hard drive, and then start playing. One more than 50 M files, in any case, REALONE prompts to connect timeowment. So if you want to include a relatively large RM file on the web, it is indeed a problem. Solutions Of course, that is, increase the code in the background, so that the RM file can be played online. But this does increase the complexity of the problem because more things are required on the server.
ASF is a data format, audio, video, image, and control command script, etc., through this format, transmitted in the form of network packets, and implements streaming multimedia content. Among them, the content transmitted on the network is called ASF Stream. ASF supports any compression / decompression encoding method, and can use any underlying network transport protocol, with great flexibility. For video files in the ASF format, it is generally played with Microsoft's Media Player. This player supports ASF's stream file format on the Internet, you can play with real-time playback, no need to completely download it.
Speaking here, you should understand the difference between the RM format video file and the ASF format video file on the network. So for big video files, or translate into an ASF format, so that users can play with a problem of waiting for too long while downloading.
