[MPlayer-users] AVV sync problem for MKV(RV40+Cook)

[张海珅]

Hallo every one!
  
 I got some MKV video sources.
 But, when I played them with mplayer, I got the messages below in the console.

From the log, I found the output of print_status() is not correct.  The value of (a_pts - audio_delay) is nearly 0 all the time. 
 
When I play other media files, the value of "a_pos" is similar to the value of "sh_video->pts".  And the value of "AV_delay" and "c_total" are nearly zero.
 
My OS is gentoo.
 
My mplayer version is 1.0_rc4_p20101114.
 
I can play the same mkv video file in Windows (with KMplayer) correctly. 
 
This file is not HD video file. And my laptop can play H264 HD movie (RMVB or MKV format) correctly. (So, this may be not the CPU load problem.)
 
 
 
Could any body give me some clues? (Is this a known bug of Mplayer to deal with some MKV files? Or, Is this a bug of my MKV video source files?)
 
Thank you very much for your any help:)
 
 
 
Sincerely,
 
Hyson
