ffplay -f video4linux2 -framerate 30 -video_size hd720 /dev/video0

sample script above doesn't work: "Segmentation fault"

i can use mplayer:

mplayer -tv alsa:input=1:driver=v4l2:width=720:height=540 -vf screenshot -vo x11 tv:// 

three options are related to video input setting:
1) driver=v4l2
2) video size: width=720:height=540
3) input=1, in xawtv, this option is specified as 
"Video Source = Composite1"

what are their corresponding options in ffplay?
/dev/video0 doesn't seem to be needed on command line

i needn't specify channel, i use remote control to change channel.

Thanks!
