LS所言极是!x264从前是只吃avs,avi,但是现在几乎所有通吃了,如果连resize,crop都不用的话,直接喂给x264其实更直接~
但是我非常感谢taro的解释,说的很明白!受教了!!
resize和crop的话,x264也已经支持了……techneek 写了:LS所言极是!x264从前是只吃avs,avi,但是现在几乎所有通吃了,如果连resize,crop都不用的话,直接喂给x264其实更直接~

代码: 全选
Filtering:
--vf, --video-filter <filter0>/<filter1>/... Apply video filtering to theinput file
Filter options may be specified in <filter>:<option>=<value> format.
Available filters:
crop:left,top,right,bottom
removes pixels from the edges of the frame
resize:[width,height][,sar][,fittobox][,csp][,method]
resizes frames based on the given criteria:
- resolution only: resizes and adapts sar to avoid stretching
- sar only: sets the sar and resizes to avoid stretching
- resolution and sar: resizes to given resolution and sets the sar
- fittobox: resizes the video based on the desired constraints
- width, height, both
- fittobox and sar: same as above except with specified sar
- csp: convert to the given csp. syntax: [name][:depth]
- valid csp names [keep current]: i420, yv12, nv12, i422, yv16, nv16, i444, yv24, bgr, bgra, rgb
- depth: 8 or 16 bits per pixel [keep current]
note: not all depths are supported by all csps.
- method: use resizer method ["bicubic"]
- fastbilinear, bilinear, bicubic, experimental, point,
- area, bicublin, gauss, sinc, lanczos, spline
select_every:step,offset1[,...]
apply a selection pattern to input frames
step: the number of frames in the pattern
offsets: the offset into the step to select a frame
