In This file video faster 1-2 secs

Didro: The Nano cannot play a fullscreen file at 30fps. Try encoding either smaller than full screen, or at 25fps. Also, your file is slightly larger than the screen.

 I wanted to write that I always encode video with FPS 24, but I looked in my make_video.bat file and found -ofps 30.  I think problem is in that, cause files with 24 plays good.
I created two bat files: one for *.mpg files, second - for *.avi. And I forgot to edit make_video_avi file to -ofps 24

But i have file which has video ahead audio in 1-2 seconds.

Colombo/Didro,

Can you try the latest version of mpegplayer (i.e. the latest Current Build), and let me know if the a/v is better now?

Thanks.

[Colombo]

Now very nice av sync! Thank you, Dave.

[Colombo]

hm but after 2 minutes, progressing faster video

[Llorean]

Do you have Skip Frames and Limit FPS both on?

[Colombo]

Llorean yes.

Progressing Video(min)-Audio(sec) unsync:
0-0
2-0.5
4-1

[Llorean]

And do you have a sample file that has this problem?

[Colombo]

Any video file has this problem.

[linuxstb]

Any video file has this problem.

No - I have played files up to an hour long with no a/v sync problems, and so have lots of other people.

Can you provide a sample file for me to test?  Preferably one where it is very easy to see the a/v sync go wrong.

Thanks, linuxstb. Every day mpegplayer is becoming better and better. New improvement in latest build fixed A/V sync in files which had video ahead.

Now about bad   : Video still is not so smooth as before, but as I know you are working with it. Also I noticed one bug. Maybe it is not so important, but sometimes after entering to menu it becomes imposible to choose menu options because Scroll up and down "freezes". You only can  return to video, or after random pressing on different buttons it starts to work.

Sorry, that I am writing here that I have to write in bug reports or feature requests but...  

Also MENU button doesnt enter you to menu when video is on pause.

And have to say, that i like programming and I even looked at mpegplayer sources but it is difficult to understand all without system api/calls knowing. Maybe this question is frequent but where can i find system api's. I looked in plugin.h but there is only list of functions(apis) without explanation.

Thank you for reading my long and offtopic post

I already posted link to video. http://athena.divshare.com/launch.php?f=308453&s=f25 - progressive unsync: after 4 min video, video faster than audio 1 sec. Ipod Nano.

That video appears to stay in sync on my Nano just fine, which is why another one was asked for.

You have chosen a VERY bad sample video, since it's just music poorly synced to scenes. Do you have a video in which there is proper recorded dialogue for the scenes so that we might have a better point of reference to where the syncing calls out of place?
