首先，我们需要使用FFprobe来提取Mastering Display和Content Light Level元数据。我们要告诉它只读取第一帧...
3a的转换由wire format color space(实在搜不到)来指定,但应该就是显示器的颜色空间,例如SDR显示器就需要做一次伽马校正,HDR10显示器就需要做一次逆PQ(或称ST.2084)电光传输函数的变换。 完成上述步骤后,Framebuffer(没错,还是在Framebuffer里)里的数据就会扫描到你GPU连接显示器的那条线里,然后显示。 Windows的...

Keep in mind that encoding standards can be misleading. A monitor that indicates support for HDR10, HDR10+, DV, or HLG input doesn’t by itself indicate the monitor’s level of capability or actual performance, only that it can successfully decode the HDR content into a video signal. A scr...
Using a 16-bit per channel integer format, 65536 discrete values are available to store per-channel data. This encoding is a simple linear distribution of those 65536 values between 0.0f and an arbitrary maximum value (100.0f for this sample). The alpha channel is unused. Here is the formul...
HDR content takes advantage of WCG by encoding videos using more of those available colors. When you watch HDR material on an HDR TV, these additional colors add to realism — because they better match what the human eye is capable of seeing in nature — but they also improve things like ...
In the current release, the only encoding format that supports SoftwareBitmap for AdvancedPhotoCapture is uncompressed NV12. So, if you want to use this feature, you must specify that encoding when you call PrepareAdvancedPhotoCaptureAsync.

此外,另外三套标准已经被批准为用于修改A/341标准的候选标准,这样它们就可以像PQ一样被设计者们规范地使用,它们分别是:ST 2094-10 SEI message,全范围信号编码(full-range signal encoding)以及ICtCp color representation。同样,数字视频广播(DVB)已经通过欧洲电信标准协会(ETSI)发布了他们的第一个HDR标准TS 101 ...
