Mplayer를 콘솔에서 실행하면

A: 2.1 47% 이런게 떠서 조사


오홍 니가 status line이냐?

--quiet Make console output less verbose; in particular, prevents the status line (i.e. A: 0.7 V: 0.6 A-V: 0.068 ...) from being displayed. Particularly useful on slow terminals or broken ones which do not properly handle carriage return (i.e. \r).

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.

암튼.. 끊어지는 경우 audio cpu 항목이 100%를 넘어서는데

단위 시간(프레임이라던가)을 디코딩하는데 걸리는 시간을 기준으로 측정하는것 같기도 하고..
