RE: Kodi DSPlayer – DirectShow Player for Windows - Warner306 - 2015-05-10 HDR to SDR: Resources Toolkit Choosing a Display Color Gamut | Choosing a Gamma Curve Topics Covered:
Choosing a Static Target Nits with Profile Rules hdrVideoPeak, AvgFMLL and AvgFALL Profile rules are available for HDR sources that can assign a desired display target nits to each video before playback based on the source's peak brightness. This is a way to optimize the presentation of HDR sources by choosing ranges of display target nits that are ideal for each source. The use of profile rules may not be necessary now that madVR can dynamically adjust the display target nits as the video plays. HDR profile rules are most effective when matched to the dynamic range of the video. Sources with a higher dynamic range tend to work best with higher target nits that preserve more contrast and sources with a lower dynamic range tend to work best with lower target nits that preserve more brightness. Advantages of Using Static Target Nits Profiles:
If you wish to use HDR profile rules to pre-select a static display target nits for each movie, it is advised to first prepare a measurement file for each video using madMeasureHDR. These measurement files allow madVR to know the average peak brightness of the source before playback and select the profile rule that best matches the known source peak brightness. Available HDR Profile Rules: hdrVideoPeak hdrVideoPeak is the maximum peak brightness of any pixel in the source. hdrVideoPeak uses the MaxCLL (Maximum Content Light Level). If MaxCLL is 0, or if both MaxCLL and MaxFALL are rounded to an even multiple of 50 (e.g. 500/500 or 10000/450), then the MaxCLL is considered invalid and the mastering display maximum luminance is used instead. Sources measured with madMeasureHDR will set hdrVideoPeak to the measured peak of 99.9% of all frames to exclude any outlying pixels, or a valid MaxCLL, whichever value is lower. AvgFMLL AvgFMLL stands for Average Frame Maximum Light Level: The average peak brightness of all measured frames in the video. The average peak of all frames is probably the best representation of the overall brightness of a movie to avoid clipping the majority of the specular highlights. AvgFALL AvgFALL stands for Average Frame Average Light Level: The average distributed peak brightness of all pixels in a frame for all measured frames in the video. This value is less useful than AvgFMLL for judging highlight clipping, but can be valuable in setting the desired brightness and contrast for the presentation. Videos with a high AvgFALL will appear subjectively brighter than videos with a low AvgFALL, even if the peak brightness of the source fails to reach a high maximum frame peak. Note: AvgFMLL and AvgFALL are only valid if a measurement file exists for the selected video. HDR profile groups are created under devices -> hdr Sample of HDR Profile Rules (Thanks to Manni at Doom9) Tip: To get the most out of HDR profiles in madVR, it is advised to create a blank folder named "ShowHdrMode" and place it in the madVR installation folder. This will show the active display target nits selected for the video in the madVR OSD. Custom or Dynamic Display Target Nits with madMeasureHDR Measurement Files If you browse through the madVR installation folder, you will find a special utility there named madMeasureHDR. This tool is designed to populate a file with frame-by-frame HDR10 metadata from any HDR10 video read and decoded by madMeasureHDR. The metadata created by madMeasureHDR can be used by madVR when that same file is played with tone map HDR using pixel shaders selected. The Command Prompt utility decodes the full video prior to playback using a LAV Video decoder and analyzes the brightness of each frame in the video and stores all measured frame peaks in a single digital .measurements file. This includes the full brightness histogram for every frame in the video that describes the measured frame average light level and frame peak brightness of each video frame. When the video file is played, madVR reads the completed .measurements file and uses the stored frame measurements to improve the accuracy of its dynamic tone mapping. The.measurements files include an embedded field for entering a hard-coded display target nits for each video frame. Two user-created tools have been developed to edit this field automatically or manually with user-controlled values. pandm1967's simple tool allows for the entry of a static display target nits for each movie into the target nits field of each measurement file. Values entered in the measurement files permanently override any values entered in the madVR control panel. pandm1967's simple measurement tool: Soulnight's MadmeasureHDR Dynamic Optimizer tool takes this a step further by embedding a display target nits for every frame in the video. This continuously adjusts the display target nits as the video plays to dynamically optimize the brightness and contrast of each scene in the video. Advantages of Using a Dynamic Target Nits:
Soulnight's tool provides the same functionality as checking apply target nits option (Coming Soon!) in the madVR control panel when no measurement file is available. The formulas used to select the display target nits are identical. Soulnight's tool has the advantage of using the pre-measured frames to know the scene and chapter cuts ahead of time to reduce false detections of individual scenes and chapters and present smoother transitions in brightness caused by resets to the display target nits at each scene change. Soulnight's MadmeasureHDR Dynamic Optimizer tool: How to Use madMeasureHDR to Create Dynamic HDR10 Metadata Files Instructions on how to use these tools along with madMeasureHDR to create .measurements files for HDR10 videos embedded with a hard-coded static or dynamic display target nits are provided below: Instructions: Using madMeasureHDR to Create Dynamic HDR10 Metadata RE: Kodi DSPlayer – DirectShow Player for Windows - ashlar - 2015-05-10 Cool! New toys to play with. Thanks Warner306 for the heads-up. With aracnoz's continued improvements we are so close to an ultimate solution that... well, it still seems to good to be true, I have to be honest. RE: Kodi DSPlayer – DirectShow Player for Windows - freddy12 - 2015-05-10 Would you gain much with this using a intel nuc hd4400 or is this for more for a higher power unit RE: Kodi DSPlayer – DirectShow Player for Windows - vicmanpergar - 2015-05-10 wow..... And i still have to understand the basics of madVr... hehe anyone can explain to me what's the meaning of target rectangle 0, 1, 1920, 1081 ? RE: Kodi DSPlayer – DirectShow Player for Windows - tiben20 - 2015-05-10 (2015-05-10, 12:27)vicmanpergar Wrote: wow..... the 2 first number is the position of the top left corner of rectangle and the 2 last is the bottom right i suppose its the rectangle where everything is rendered the video calibration within kodi is pretty much the same thing it change the target rectangle RE: Kodi DSPlayer – DirectShow Player for Windows - vicmanpergar - 2015-05-10 (2015-05-10, 12:39)tiben20 Wrote:(2015-05-10, 12:27)vicmanpergar Wrote: wow..... Hi Tiben, and thanks.... But... Being my plasma 1080p native and having everything configured as native, without any scaling from the GPU, shouldn't it be 0, 0, 1920, 1080? I get a 0,1, 1920, 1081 RE: Kodi DSPlayer – DirectShow Player for Windows - aracnoz - 2015-05-10 with madvr 0.88.1 there is some problem with exclusive mode, mouse events don't pass to kodi and performing a stop can crash because the loop where dsplayer handles the messages remains locked in some way by madvr then for the new options madshi has not upgraded the api to manage the settings, so i cannot upgrade the kodi gui my advice for now it's to use madvr 0.88.1 just for test with dsplayer if you want stability RE: Kodi DSPlayer – DirectShow Player for Windows - tiben20 - 2015-05-10 (2015-05-10, 12:47)vicmanpergar Wrote:your absolutely right , i have no idea why it default to 1 , 1981(2015-05-10, 12:39)tiben20 Wrote:(2015-05-10, 12:27)vicmanpergar Wrote: wow.....

They are 1080p but miss the target rectangle. I don't understand why this is either. RE: Kodi DSPlayer – DirectShow Player for Windows - Warner306 - 2015-05-10 The new madVR causes DSPlayer to crash, so I would stay away. The madVR API probably hasn't been updated because the new features are experimental. Some will be removed, while others will be simplified for the end user. RE: Kodi DSPlayer – DirectShow Player for Windows - vicmanpergar - 2015-05-10 @warner Thanks to u as well. At least I wont worry too much about the rectangle RE: Kodi DSPlayer – DirectShow Player for Windows - aracnoz - 2015-05-10 @Warner306 can you make a test with madVR 0.88.2... it seems to solve the problem with messages locked in dsplayer but there is always a problem on stop, kodi remains unresponsive after the stop happens the same thing with mpc-hc after close a video with ctrl+c or with file - close this it's how appear my mpc-hc after the close video madshi it's not able to reproduce this issue edit ok i think that i solved the crash with madVR 0.88.2, it's easly also reproducibile with the latest stable build of mpc-hc (but not with the latest nightly), anyway i think that there is always something that don't work as he should with messages RE: Kodi DSPlayer – DirectShow Player for Windows - Warner306 - 2015-05-10 (2015-05-10, 11:29)freddy12 Wrote: Would you gain much with this using a intel nuc hd4400 or is this for more for a higher power unit Integrated graphics cards won't get you much further than the default settings. But DSPlayer can still be configured to look superior to DVDPlayer. RE: Kodi DSPlayer – DirectShow Player for Windows - AppData - 2015-05-11 Madvr 0.88 seems to be crashing my Kodi, Potplyer and mpc. Is it madvr or something I did wrong?

Is it madvr or something I did wrong? DSPlayer isn't ready for the new madVR. The new features will be subject to change in the near future, anyways. So I would wait for a month or so to upgrade. madshi has put these features out to the public for feedback. Based on that feedback, they will be finalized and included in a future version of madVR. |
