Use whatever gets the job done. As for scaling and cropping, to the best of my knowledge, ffplay(1) supports all the options that ffmpeg(1) does. Here is what I for example use when capturing my Famicom: ffplay -sws_flags fast_bilinear -framerate 60 -video_size 1920x1080 -vf crop=iw-360:ih,scale=-1:1080 $DEV.
