[FLEX] Video player problems

1

Well Ive been trying to make a small flv player in flex, came across 2 problems.

  1. How would you make a slider to control the video (Is it called a scrubber?)?

  2. How do you change the icon of a button at runtime? (For the play/ pause button, changing the labels I can do, the icons have stumped me).

I couldn’t find an example of a mp3/flv player online made in flex that has either of these, so I havn’t got a clue how to proceed.

Thanks.
