[MPlayer-users] wrong answer to the slave mode command(get_propertytime_pos) on audio

[Zongyao Qu]

I found mplayer + ffmpeg has added a new feature in somewhen, 
Which display the album art of an audio file if there is one.

But the time_pos of the audio file goes wrong, it outputs a very 
big minus number.
and also, the console output of the current A, V time goes weird.

the output of the console is attached below. 
---------------------------
subtitle font: load_sub_face failed.

Too many audio packets in the buffer: (4096 in 3126509 
bytes).
Maybe you are playing a non-interleaved stream/file or 
the codec failed?
For AVI files, try to force non-interleaved mode with the -ni 
option.
