Play in command line BSPlayer list (.bsl) with options
 

I have a file named "playlist.bsl" like this:

video1
video2
video3

In BSPlayer's help:
bplay "playlist.bsl" [options]
2 of this options are -fs (full screen) and -ar=x:y (aspect ratio)

Well, I write << bplay "playlist.bsl" -fs -ar=4:3 >> and only video1 is viewing with these options, video2 and video3 work with default options
