These days are studying flashcom's MP3 library. Flashcom, I am more unfamiliar. I spent a day and a half, I spent a video recording. I didn't put the speaker in the studio. I saved the speaker. I didn't hear the machine's voice for more than a year. I know very little on this aspect of the audio. I am very grateful here. I am very grateful to the selfless help of the cloud. Look at the streaming media package of the Macromedia media component, I feel that it is quite big, the following analysis It is a subclass of NetConnection based on the RTMP protocol. In the MX.Controls.streamingMedia package.

The connection queue is not as good as a queue. This makes the connection become advanced, this is not very good. If the POP comes out, the RTMPConNtion connection time is too long, and there is a new connection. That in the stack It is not always the day. And the connection does not share a level, it is possible because it is a Player service, so it is not divided into ~~~~~ Good Faint.
