probably need some kind of keep-alive events as well? as live feed are generally silent in terms of user activities.

The function we need in player:

1.    Play button
2.    Time Line
3.    Volume Tuneup
4.    Full Screen
5.    Throw Something
6.    Comments
7.    Share

The function will display only in no_full screen:

5.    Throw Something
6.    Comments
7.    Share

Myself comment:
1. The share button will be displayed at the right of the player. (Make a button to append some share button.)
2. The play button and fullscreen button can append at the top of time line so that the div only puts time line and volume tune. (If this is unnecessary, we can ignore it.)

Request for top/parent postMessage APIs like

• vid
• video start
• timestamp when original live started
• damaku w/ timestamp

, then I can create examples like "Hanzi Machine Gun" w/o mess up the project.
