a_leonov

I try to use complete amx module, I cant to make it works. One preview image works without problems. I wont understand how mxa-mp fils 10 slots of its preview images. As I can knew from amx module, its periodically switching matrix and save frames of each input. But I didn't find any sign in command that mean any slot exept first. So how it works? ))
