avs在linux下需要自己编译:

eq[=brightness:contrast] (OBSOLETE)yjcong 写了:不是。 我当然是会试的拉jarlyyn 写了:mplayer 那个亮度参数 mencoder应该也能用的-brightness is not an MEncoder option
Exiting... (error parsing command line)
Software equalizer with interactive controls just like the hardware equalizer, for cards/drivers that do not support brightness and contrast controls in hardware. Might also be useful with MEncoder, either for fixing poorly captured movies, or for slightly reducing contrast to mask artifacts and get by with lower bitrates.
<−100−100>
initial brightness
<−100−100>
initial contrast
eq2[=gamma:contrast:brightness:saturation:rg:gg:bg:weight]
Alternative software equalizer that uses lookup tables (very slow), allowing gamma correction in addition to simple brightness and contrast adjustment. Note that it uses the same MMX optimized code as −vf eq if all gamma values are 1.0. The parameters are given as floating point values.
<0.1−10>
initial gamma value (default: 1.0)
<−2−2>
initial contrast, where negative values result in a negative image (default: 1.0)
<−1−1>
initial brightness (default: 0.0)
<0−3>
initial saturation (default: 1.0)
<0.1−10>
gamma value for the red component (default: 1.0)
<0.1−10>
gamma value for the green component (default: 1.0)
<0.1−10>
gamma value for the blue component (default: 1.0)
<0−1>
The weight parameter can be used to reduce the effect of a high gamma value on bright image areas, e.g. keep them from getting overamplified and just plain white. A value of 0.0 turns the gamma correction all the way down while 1.0 leaves it at its full strength (default: 1.0).
