Video window configuration
Move the mouse to the bottom right of the video window. You will see an arrow indicating that this window is resizable. Drag the window to the size you want.
The blue bar to the right of the video is the volume bar, showing the volume of the microphone and speaker.
To configure the volume:
Right click on the video window and choose -> setting-> microphone
Check other user's audio/video
The webcam icon is visible after a user's name in the userlist if he/she has already published their audio/video.
(see #2 in picture 1)
To see that user's video, click the icon.
After you've published your video, other users will see a webcam icon next to your name.
2). How to use video chat in private chat
If you would rather publish your video only to a specific user rather than the whole chat lobby, activate a private chat window by double clicking his/her username first. The "Publish my video" webcam icon will appear in the menu above the input area.

Using this method, no users apart from the user you specified will be able to view your video.
If the receiver wants to show their video to you, they will also need to click the "Publish my video" button to publish their video.
