Hi,
Oh, yes,the trouble is in the programe. At the end of the programe , I use XvSet
to
free the video memory,but after the founction, I must do something about SetPort or
GetPort attribute, or use XFlush(), the the XV_FREE_FB will go to founction. Otherwise,
the Xvsetattribute will not be setted. I'm very bewildered about the use of these
founction.
It seems that the XvSet/Get cannot be sended to server timely.
I don't why it must be done as these.
Thanks Mark! Thanks all!
