I didn't update my blog in a few days. In the past few days, I think some details of the X project in addition to the collective activities of the Weekend Party Organization. MS NetMeeting is basically excluded by me. First, NetMeeting is basically a component of H.323 complete package; in detail in the H.323 protocol, the audio of the online conference is a mixture of multi-audio, and video is the earliest connection video, want to be A multi-channel video in a meeting is impossible. I have designed an implementation, establish a web conference between 3 sets of Win2000 machines A, B, and C. At the machine A, B has a camera, then open two browser processes on the machine C (Net Meeting COM Object, because Net Meeting can only run an instance, so you want to open two net meetings at the same time. Yes), in two processes respectively connect A, B, which can see the mutual visibility of the conference call in the process on the three machines, but the key is that the video is the communication of the communication established. . So this program is unlikely - that is, how many processes are taken, while switching of Windows processes is also an important issue. In order to separate multiple channels, I want to take two ways, first of all, programming Net Meeting's CODEC, that is, the method I mentioned in the previous blog. Second, if I can change the port number of each Net Meeting instance, then I can separate multiple signals, but this is usually impossible, and the port of Net Meeting should be fixed.
Maybe I will split H.323 components into several parts to solve this problem.
