# AviSynthTwoFivePixelType

The internals of VideoInfo.pixel_type has been completely changed. The type has been changed from byte to int, and now contains different information than before. This is important when building a Source filter, when you have to set the pixel_type. You have to change your constants to reflect this change.

In general filters should not care about these values at all - only if they set or modify them. For checking what colorspace the video material is in, use one of the following functions in VideoInfo.

- bool IsRGB()
- bool IsRGB24()
- bool IsRGB32()
- bool IsYUV()
- bool IsYUY2()
- bool IsYV12()
- bool IsPlanar()

If you need to set the pixel type, use a syntax like:

`vi.pixel_type = VideoInfo::CS_YUY2; // Version 2.5 syntax`

instead of:

`vi.pixel_type = VideoInfo::YUY2; // Version 2.0 syntax`

Other possibilities are:

- CS_BGR24,
- CS_BGR32,
- CS_YUY2,
- CS_YV12, // y-v-u, planar
- CS_I420, // y-u-v, planar
- CS_IYUV // same as above

The last two are automatically converted to YV12, so filter writers should not worry about these.
