Spørgsmålet er besvaret i mplayers FAQ[1]:
Q: What is the meaning of the numbers on the status line?
A: Example: A: 2.1 V: 2.2 A-V: -0.167 ct: 0.042 57/57 41% 0% 2.6% 0 4 49%
1.00x
A: 2.1
audio position in seconds
V: 2.2
video position in seconds
A-V: -0.167
audio-video difference in seconds (delay)
ct: 0.042
total A-V sync correction done
57/57
frames played/decoded (counting from last seek)
41%
video codec CPU usage in percent (for slice rendering and direct rendering
this includes video_out)
0%
video_out CPU usage
2.6%
audio codec CPU usage in percent
0
frames dropped to maintain A-V sync
4
current level of image postprocessing (when using -autoq)
49%
current cache size used (around 50% is normal)
1.00x
playback speed as a factor of original speed
Most of them are for debug purposes, use the -quiet option to make them
disappear. You might notice that video_out CPU usage is zero (0%) for some
files. This is because it is called directly from the codec and thus cannot
be measured separately. If you wish to know the video_out speed, compare
the difference when playing the file with -vo null and your usual video
output driver.

I den dårlige stream er lyd og billede ikke synkront. Det kan skyldes et
væld af forskellige ting, lige fra buggy codecs til mangel på bandwidth.
