FFDSHOW -work with avx 512 ?HDR ? REC 2020 ? amd ?

do FFDSHOW video and sound
works with :

1. Intel's AVX 512 commands ?

2. HDR - do you support ? to what level 1000/2000NITS ?

3.Can FFDSHOW convert SDR to HDR ?

4. Which computer is recommended for FFDSHOW? Intel or AMD ?

5. Does FFDSHOW support new commands for new AMD processors Threadripper 1950X ?
SHA / Secure Hash Algorithm extensions
F16C / 16-bit Floating-Point conversion instructions
FMA3 / 3-operand Fused Multiply-Add instructions
SMAP / Supervisor Mode Access Prevention
SMEP / Secure Mode Execution Protection
Precision Boost
Extended Frequency Range

6. Does FFDSHOW support REC 2020 ?
Can convert color from SDR to REC 2020 ?

7. i open a lot of tabs in FFDSHOW
the film is very slow, as if the processor is too weak
which processor is best for FFDSHOW ?
( when i open many tabs on-FFDSHOW )

thank you for your answer

ffdshow has been abandoned for years, it doesn't support any modern instruction sets or any sort of HDR.

it says there was an update on 2014-06-28
it is very unfortunate to hear

which system is best coded today? KLITE ?

You seem to confuse "codec" (encoder / decoder) and "pack".

K-Lite is a collection of many different decoders from many different authors, for many different purposes. It even included ffdshow as multi-format decoder.

If you had read this thread before asking, you would know that the next evolutionary step after ffdshow is "LAV Filters". Look at nevcairiel's signature.

i very much hate "LAV Filters"
you can not tune them professionally like FFDSHOW
Still with KLITE the questions remained .
FFDSHOW IN KLITE

Well, this may rather be a request for LAV Filters than a complaint in the ffdshow thread, which is futile now, as it is abandoned...

And, as just explained, the "K-Lite pack" is only a collection. It is not decoder software on its own. The author of the K-Lite pack did not develop a codec.

encoded that can not be directed seriously like FFDSHOW
for me it's a big problem!

because LAV Filters Does not bring quality in image or sound!
he plays everything, but not quality

why are there no encoders you can tune like FFDSHOW ???

it's a shame to see that there are no groups to develop good, serious encoders that can be directed .

too bad that no one buys the FFDSHOW and develops the encoders for money .
I would be happy to pay FFDSHOW money for quality encoders

FFDShow is not an encoder, it's for decoding and processing.
For Video processing you can use madVR and for audio processing you can still use ffshow after the decoder.

Why use madVR
FFDSHOW does everything better (although not updated from 2014)
that means a lot not good things about development

i'm trying to direct the madVR not contributing anything good
maybe someone here has a right direction for madVR? For OLED ?
which computer processor is good for madVR ?

i have an OLED screen that I must say is not worth anything to the computer
maybe because all VGA cards are not WRGB and RGB
the LG processor is bad
UPSCALE LG Worse
there are no good shades
there are no grays
contras are bad

why don't you sit back for a little bit and rethink a bit...

i mean you are saying stuff like this:

maybe because all VGA cards are not WRGB and RGB.
every playback device is using YCbCr and RGB so the PC VGA has nothing todo with it...

so you are saying madVR is not contributing anything good and you don't even know it is mostly using the GPU not the CPU?

while LG is not known for good processing you should really fix your settings...

I have no idea what you're writing about? Do you have any idea what you are writing?

so what wrong with the truth ?
you want to calibrate a video card ( RGB/YCbCr )to the WRGB screen there are large backlight ( oled light) issues in the OLED, there are brightness issues
Not to mention that LG's algorithm system is very poor and distorted image

Quote:

no
not every playback device is using YCbCr and RGB
OLED TV have only YCbCr but it has a problem that the OLED color is WRGB
and that does not work out very well at calibration.

amazing you success understand!
1. madVR adds different types of noise in the image
2. madVR Causes problems of uneven sound to the lips
3. madVR running it takes up to 26% of CPU power not GPU
4. madVR in LED works better

i curse every day I bought an OLED, not a good connection to the computer

What to fix? How to fix ? You throw things in the air
I paid for 2 professional calibrations for $ 600 and got a worse
picture!

I said maybe I'll learn from others by their calibration
It turns out that no one really knows how to calibrate OLED and they all invent stories :
Home Theater Geeks 324: Leo's LG OLED Followup
https://www.youtube.com/watch?v=sBDun9fbEWU&t=355s

In program 323, they made a professional calibration with equipment worth $ 35,000 on a $ 4000 screen

and they did not succeed, in they site published the results of the calibration was discovered inaccuracies, lack of professionalism, irrationality
and for 60 minutes (In program 324 ) they told 100 stories and they promised to calibrate OLED again and tell about results, which did not happen !!!
( Most of the experts in their forum who raised the problems in their calibration that the results are illogical - were deleted from the forum !!! )

now ask but no forum does not register the truth?
1. The OLED UK and USA forums are managed by PRs, eliminating any question or problem in OLED!
2. LG pays a lot of money to publicists, site owners and mute people!
the trips to exhibitions abroad + hotels LG pays them.

Note:
OLED shows full Blu-ray through OPPO in quality !
but any other video that is not Blu-ray , full of problems

i know it not a good idea to answer any of this delusion so i make it short.

an oppo (and every other BD player) send RGB or YCbCr like any other PC gaming console and settop box.

this is the fundamental of video processing and this is missing so nothing more to say.

I recently purchased an LG OLED55C7P and was able to calibrate it quite successfully. It is now extremely accurate in SDR but only fairly accurate in HDR.

I used a Display 3 Pro I profiled on my TV with a i1 pro2. My white point looks very good, contrast is amazing, and my gamma is a near perfect pure power 2.4. The highest error is at ~2 dE and most colors are <1 dE (DCI-P3, D65, BT.1886), and that is before madVR with a 3DLUT.

I am not sure why your professional calibrator failed so badly but it did take me some experimenting with my TV's options to figure how what to tweak and what to leave alone. Using the TV's color management was not good, nor was using its 20-point white point adjustment. However, the two point white point adjustment worked quite well and I was able to get a near perfect gray scale, every patch in the entire 21 point gray scale was <1 dE.

I do have some minor banding I was unable to get rid of but otherwise I am very happy with the image quality and its before software calibration.

Of course this might not be the case with older models but it isn't a problem calibrating OLED TVs in general.
