GPIO outputs flash

[mrtinvan]

Is there anyway to make GPIO outputs flash? I want an LED to flash while a media clip is playing. Could i create a output state in the gpio driver?

Yes, but its a bit convoluted
Create a second mediashow with two audio tracks. They should have a blank location and a duration of say 1 second. Use animation to turn the gpio on or off at the start of each track
At the start of the video track start this mediasshow with an open show show control command, at the end close the show.
Or you could modify the gpiodriver as you suggest.
