OK, objections anyone? The I'll modify the patch accordingly. I'm happy with that and I don't mean to be nitpicking but as far as "ffplay -loop -1 -autoexit" is concerned the situation would then be the same as in my original patch with "ffplay -loop -autoexit", just with the additional (useful) option to specify a loop count.
