At first, I?m from Germany and my English is not the best but i?ll give it a try

I?m searching a Backlight-Time-Control Plugin. A small Command in a line of a Screen, that define a amount of time in that the Background-light fades to an minimum/maximum value.
for Example: Winamp... It starts playing. Then, after e.g. 5sec the Backround fades out to the seted minimum value. The speed can set by an other value (seconds)
The command Could look like this:
$dll(btc.dll,0,5,3,12)
btc.dll - backlight-time-control
0 - 1/0 (fade in / fade out)
5 - begin after 10sec
3 - timescale (after 3sec it reached the min/max Value)
12 - % minimum/maximum brightness (depending on the 1. Value)
I do not know if it is possible at all, but when, anyone can give it a try
I would develop it by myself but i?m not able to do this because it exceeds my skills


Thx Fr33man
