Does QMC2 already have the feature to record videos, using MAME -aviwrite, -mngwrite and -wavwrite commands?
I searched about this all the frontend and in "The 'ultimate' guide to QMC2", but I didn't found any mention of this.
I'm considering write a request for this feature in the bug tracker, but I just need to know if this feature is already available in any way in the QMC2.

•To record an AVI/MNG/WAV:
mame <game> –aviwrite <filename>.avi
mame <game> -mngwrite <filename>.mng
mame <game> -wavwrite <filename>.wav

To exemplify one of the countless uses of this feature, here is an video someone made using this commands some time ago to simulate how the N64DD would work at normal speed.
