Play mplayer smoothly

**GlassFish** · 04-12-2009

Hi
I am new to linux and I use the Mplayer to play movies and other videos. But the find a problem with MPlayer, it pauses and jumps when it is finished. When I play one video and press the next button it pauses for a long time. I use the terminal to play mplayer, this is the command

Code:

mplayer -playlist your_play_list

So, is there any other option to make mplayer play smoothly. I do not like when the mplayer jumps and pauses, its frustrating. Any idea of how to fix the problem. Am I right with the command and its options or I should try something else. Any solution will be appreciated.

Hello
I think you should try the -autosync option, and it would be much better to try it with value 30.
The following is the output of the man pages

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.

Alternatively one more option is to try -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.

Hope this solves your problem.

Hi
I tried your options, it is much better now. But the pause and the jump problem still persist. I am not sure that I can play the videos smoothly with mplayer, now it is showing a blank screen when I when the video is stopped. Any help or advice on this. But thanks it is much better than before. Do you know any more option which i can use with the command so that it can play the videos more smoothly. Any help will be appreciated.

Hi
Ok, you can try the option noaudio, and if the mplayer plays the videos smoothly the just adjust your -autosync value. I am not sure but you can also try -framedrop. Here is the code for it

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.

Check that you have not application running at the same time when then mplayer is running.
