fftools/ffmpeg: make specifying thread_queue_size turn on threaded input
Threaded input can increase smoothness of e.g. x11grab significantly. Before this patch, in order to activate threaded input the user had to specify a "dummy" additional input, with this change it is no longer required. Signed-off-by: Marton Balint <cus@passwd.hu>
