As3 simple player [Author: qingren]

[Knowledge point]
1. Construct the video netconnection and netstream;
2. Use soundtransform to control the volume. (This consumes some energy. In As2, setvolume can be used, but as3 won't work );
3. Pause pause () and Resume playback of paused video streams using resume ();
4. onmetadata is used to receive video information (for example, the total video time data. duration );
5. Use NetStatusEvent. NET_STATUS to start and end the video stream. If the value of info. code is "NetStream. Play. Stop", you can replay or Play a new video;
// The above is just some of the most basic video knowledge. I hope you will be able to get something from as3. this will be my greatest pleasure.

[STEP]
Step 1: Create the play button and pause button. The instance names are play_btn and pause_btn;
Step 2: draw two long Rectangles and convert them into video clips. The instance names are jzjd_mc and bfjd_mc, respectively, and serve as the loading and playing progress bars;
Step 3: Right-click the database and select "new video". In the displayed dialog box, click "video (subject to the control of ActionScript)" and drag it to the scenario. The instance name is vid;
Step 4: pull two dynamic texts in the scenario. The instance names are bftxt (display playback time) and zcdtxt (display total time );
Step 5: Draw a long rectangle and convert it into a video clip. As the volume bar, the Instance name is ylt_mc;
Step 6: Draw a small circle and convert it into a video clip. As the volume slider, the Instance name is ylhk_mc;
Step 7: Write the following code on the frame:
