Position of watermark with Mencoder subpos subalign

My conf. now:

$cmd_mencoder = "$config[mencoder] '$video_src' -o $video_flv -of lavf -oac mp3lame -lameopts abr:br=56 -vf scale=320:240 -ovc lavc -lavcopts vcodec=flv:vbitrate=700:mbd=2:mv0:trell:v4mv:cbp:l ast_pred=3 -srate 22050 -lavfopts i_certify_that_my_video_stream_does_not_use_b_fram es -subpos 98 -subalign 2";

But.... watermark NOT CHANGE!

subpos and subalign error syntax?

thanks.

you should post in the same thread rather than create new posts...anyway you have not put the location of the sub file in your command....read my guide again for details

also you know this is not for changing the watermark image that you add from the admin pannel right?
