I have tried the -mc 0, thing seems better!
but according to the manual:
>>you may have to switch to basic A/V sync with the -mc 0 option, or
put this in >>your ~/.mplayer/mencoder config file, as long as you are
only working with good >>sources
my wmv is of coz not a good source, also, i may also need to encode
other files such as mov, 3gp, mpeg automatically via command line, is
it safe to use "-mc 0" in all the conversion ?
another choice I found is to get the correct framerate first, and
encode using this as the "ofps", is this choice better than using "-mc
0" if I need to handle various files with unknown framerate?
p.s. in order to get the FR, i use -identify -vo null -benchmark
test.wmv, the mplayer play the file once (real time) and return the
average fps, is it possible to get the FR faster?
sorry for too many questions....
