原来这样,难怪你坚持用1.9rc5 改其Color_Space=2?在什么地方改的?

project 文件 头信息 里改 另外 引用 YUV->RGB
When you use DGVfapi to frame serve, the video is always converted to RGB. This option specifies how the colorspace conversion to RGB is to be performed.
PC scale - Map output RGB to full range: YUV [16, 235(Y)/240(UV)] -> RGB [0, 255]
TV scale - Map output RGB to clipped range: YUV [16, 235(Y)/240(UV)] -> RGB [16, 235]
This option affects conversion to RGB, which occurs in only two places in DGMPGDec: 1) in the display window of DGIndex, and 2) the video served by DGVfapi. Generally, unless you have a good reason to clip the RGB, you should select the PC scale option.
Two well-known situations for using TV scale are as follows:
You are using DGVfapi to serve video to TMPGEnc and you have the Output YUV Data As Basic YCbCr Not CCIR601 option checked (it's unchecked by default).
You are using DGVfapi to serve video to CCE with the Luminance Level 0 To 255 option
引用 [Color Space]
This option influences the color space conversion of display and AVI output. Most MPEG-2 streams are based on YUV 4:2:0 format. It's necessary to be converted to other popular format for display and edit.
YUV 4:2:0 -> YUV 4:2:2 -> {DirectDraw YUY2 Overlay} -> Huffyuv, MPEG-4, DV YUV 4:2:0 -> YUV 4:2:2 -> YUV 4:4:4 -> RGB 24-bit -> {GDI Display} -> most codecs
The processing of [YUV 4:2:2] is much simple and faster than [RGB 24-bit]. However, it's not widely supported by video codecs and display cards. If YUY2 Overlay is supported on your system, DVD2AVI will switch to [YUV 4:2:2] automatically. Otherwise you won't see anything when previewing by [YUV 4:2:2].
VFAPI is based on [RGB 24-bit] always (for maximum flexibility) no matter which option is selected.
