Recently, many people have been writing questions about the most popular and mature streaming media production, playback, and server-side technologies related to QuickTime pro, Microsoft Windows Media Encoder 7, and realproducer plus, I have no time to answer the questions one by one. I will sort them out below. Please take a look. Although none of the above are the latest versions of these software, it is undeniable that Microsoft Windows Media Encoder 8 and QuickTime 5.0 are only in the test phase, so the comparability is not too strong, wait until a series of their supporting software keeps up. Because some of the more professional terms do not know how to translate, so simply keep the original state, presumably better express the original intention.
