Smile How to get the Mplayer play movies smoothly ?

Hi,all ! I'm using Mplayer to play movies . And I find that Mplayer always have a pause or jump when it finishes
playing one film and starts the next one ( I'm using the command like : mplayer -playlist your_play_list) .So I want to know is there any idea to make it play smoothly ,I don't like the pause or jump when I'm watching movies. Any idea is welcome.Thank you in advance !

You might try the -autosync option try it with a value of 30 ==> -autosync 30

from man mplayer:
Code:
-autosync <factor>
              Gradually adjusts the A/V sync based on audio delay measurements.  Specify-
              ing -autosync 0, the default, will cause frame timing to be based  entirely
              on  audio delay measurements.  Specifying -autosync 1 will do the same, but
              will subtly change the A/V correction algorithm.  An uneven video framerate
              in  a  movie  which plays fine with -nosound can often be helped by setting
              this to an integer value greater than 1.  The higher the value, the  closer
              the  timing  will  be to -nosound.  Try -autosync 30 to smooth out problems
              with sound drivers which do not implement a perfect  audio  delay  measure-
              ment.   With  this  value,  if large A/V sync offsets occur, they will only
              take about 1 or 2 seconds to settle out.  This delay in  reaction  time  to
              sudden  A/V  offsets  should be the only side-effect of turning this option
              on, for all sound drivers.
Another one to try would be -cache <kb>
Code:
-cache <kBytes>
              This option specifies how much memory (in kBytes) to use when precaching  a
              file or URL.  Especially useful on slow media.

Yes,Lindy ,it is better .But it still have pause and jump .I'm not sure if I can get it playing smoothly enough but if it show a black screen when it finishes one film ,that is also good.I mean it can pause but please don't jump.

You can try it with noaudio and if it plays smoothly you can adjust your -autosync value. Just as a wild guess you can try -framedrop...

From man mplayer:
Code:
 -framedrop  (also  see  -hardframedrop,  experimental  without  -nocor-
       rect-pts)
              Skip  displaying  some  frames to maintain A/V sync on slow sys-
              tems.  Video filters are not applied to  such  frames.   For  B-
              frames even decoding is skipped completely.
Also try closing out other apps if you have some other thing running at the same time.

Hi,Lindy. I have tried that,but it is still not good enough. Maybe only some build in media players can do it with no jump or pause. Well,thank you ,Lindy.

You can use the "-fixed-vo" mplayer command line argument to avoid the "restarting" jump between videos. It works best if all the videos are the same resolution.
