使用 QVideoFrameFormat::ColorSpace 代替。
枚举视频帧的 Y'CbCr 色彩空间。
| 常量 | 值 | 描述 |
|---|---|---|
QVideoFrameFormat::YCbCr_Undefined
|
0
|
No color space is specified. |
QVideoFrameFormat::YCbCr_BT601
|
1
|
A Y'CbCr color space defined by ITU-R recommendation BT.601 with Y value range from 16 to 235, and Cb/Cr range from 16 to 240. Used mostly by older videos that were targeting CRT displays. |
QVideoFrameFormat::YCbCr_BT709
|
2
|
A Y'CbCr color space defined by ITU-R BT.709 with the same values range as YCbCr_BT601. The most commonly used color space today. |
QVideoFrameFormat::YCbCr_xvYCC601
|
3
|
This value is deprecated. Please check the ColorRange instead. The BT.601 color space with the value range extended to 0 to 255. It is backward compatible with BT.601 and uses values outside BT.601 range to represent a wider range of colors. |
QVideoFrameFormat::YCbCr_xvYCC709
|
4
|
This value is deprecated. Please check the ColorRange instead. The BT.709 color space with the value range extended to 0 to 255. |
QVideoFrameFormat::YCbCr_JPEG
|
5
|
The full range Y'CbCr color space used in most JPEG files. |
QVideoFrameFormat::YCbCr_BT2020
|
6
|
The color space defined by ITU-R BT.2020. Used mainly for HDR videos. |
This function is deprecated. We strongly advise against using it in new code.
使用 setColorSpace () 代替
