Well I have a small big problem with iframe.
<iframe src="index.php" frameborder="0" name="site" class="site"></iframe>
<iframe src="toca/player.php?volume=100" name="player" frameborder="0" class="toca"></iframe>
Simple want when the user clicks pause the volume of the iframe player to change to 0 or if the user chooses a certain volume type 50, 40, 10 ...
In case it is for a volume controller that is already encoded so it is only necessary to make it stop the volume

If you have a better way of doing this you can talk s2
