madVR 0.92.2 更新 - 極高質素影像渲染器

madVR 0.92.2更新在2017年8月26日推出

madVR是一個高質影像渲染器，當中多種出色的功能包括

高質素色度升頻(chroma upscaling)；

多種高質素縮放技術(bicubic，mitchell，lanczos，spline及nnedi3等等)；
高質素YCbCr->RGB換算法；
可以配合顏色校準器校準螢幕的色域同伽瑪；
全程使用16bit高精度處理；
最終16bit處理後會抖動(dither)到RGB的色深輸出；
避開顯示卡驅動程式對畫面的處理，避免損害畫質；
所有程序使用GPU運算。

修正當暫停播放時程式可能崩潰
修正使用DXVA2解碼和降綫HDR的影片顏色出錯
修正使用D3D11 DXVA解碼時把播放視窗移動到其他螢幕時程式會崩潰
修正使用DX10的顯示卡同時D3D11 DXVA解碼時會出現綠畫面
修正使用D3D11 DXVA解碼時影片會無故更變大小
修正使用D3D11 DXVA解碼時不能檢測到不良的HDR metadata
修正D3D11 FSE模式播放10bit時可能限制在8bit色深
HDR中"讓madVR決定"的設定在intel GPU時無效
輸出到螢幕HDR metadata不一定準確
諸如此類

madVR v0.92.2

* fixed: possible crash when stopping playback or freeing the madVR instance
* fixed: DXVA2 decoding+downscaling produced wrong colors with HDR content
* fixed: D3D11 DXVA decoding: crash when moving window to another monitor
* fixed: D3D11 DXVA decoding: green screen with DX10 GPUs
* fixed: D3D11 DXVA decoding: problems if video unexpectedly changes size
* fixed: D3D11 DXVA decoding: detection for bad HDR metadata wasn't working
* fixed: custom modes tab didn't show for AVR devices
* fixed: custom modes tab didn't show when display modes was in a profile
* fixed: D3D11 FSE mode was sometimes limited to 8bit instead of 10bit
* fixed: HDR "let madVR decide" setting misbehaved for Intel GPUs
* fixed: HDR metadata sent to display wasn't always correct
* fixed: "HDR" profile bool was not set if HDR metadata was bad/unknown
* fixed: some settings windows appeared behind a "always on top" media player
* added support for sending MaxCLL/FALL HDR metadata (if available) to the TV
* added "enable nvidia 3d.reg" to enable 3D playback with newer Nvidia drivers
* if video HDR metadata is bad/missing, default HDR metadata is sent to TV now
* when custom mode is deleted, measurements are now also deleted
* Nvidia "try custom mode" timeout increased to 30 seconds
