FFDSHOW new commands ready ? for Bulldozer

[hogtop]

Is FFDSHOW new commands ready ? for Bulldozer
Or take the time to write them?
i have 1055t amd and ffdshow not Supports SSE4A why ?

[Dark Shikari]

I don't think SSE4A (which is just lzcnt) has any use in video decoding...

[hogtop]

So what better to work with FFDSHOW :confused:
Sound? And a picture? Shades of black and more?

I think that the commands of SSE4a for ffdshow

But there is no development,
maybe more work from Intel
It takes time for developers?
maybe the developers invest more Intel processors?

AFAIK, the only active ffdshow developer is Eric Gur who has been working on Intel hardware decoding support (http://forum.doom9.org/showthread.php?t=162442). Other than that, there is no actual development going on.

Looks pretty active to me:
http://ffdshow-tryout.svn.sourceforge.net/viewvc/ffdshow-tryout/?view=log

Also I think, if support for new instruction sets was added, then it wouldn't be added to ffdshow itself, but to the decoder libraries it uses, namely libav(codec).

So we will have to wait until the ffmpeg/libav developers find ways to do something useful with the new instructions... which for some instructions might never happen ;)

Also many of the "features" in hogtop's list, like the virtualization stuff, are not related to audio/video processing at all. And some, like AVX, need OS support.

(Oh, and some, like HyperThreading and Turbo Boost don't/shouldn't need explicit software support)

Intel has enormous lead on IPC per core and per clock and power draw over bulldozer at the moment, I see no reason for BD or caring about instruction at all. Even if ffdshow eventually make use of BD new instruction set, Intel would still trump all over it using raw power alone.

There is also no reason at all to buy 2700K, since the only difference is the multiplier which you can easily and safely match with 2600K.

Well, most of that is maintaining the libraries and fixing simple bugs. A month ago clsid said that he doesn't see significant changes happening until new developers join the project: http://forum.doom9.org/showthread.php?p=1524231#post1524231

Also I think, if support for new instruction sets was added, then it wouldn't be added to ffdshow itself, but to the decoder libraries it uses, namely libav(codec).

Yep.

English is not my first language
1. I understand it better new Intel processor and no AMD :confused:
2. Because of processing power :confused:
3. I had the I7 920 and I sold Because black in movies was not good compared to AMD
Is it fixed now :confused:
4. lighting with live concerts with Intel was smeared and and not sharp Is it fixed today :confused:
5.Is the 4 channels of memory is better:confused: 2700
6. 22NM in 2012 Better for ffdshow :confused:

Do you think when your CPU has a new instruction set, every software should use it? Of course not. A software doesn't need to support ALL features of a hardware. If the software cannot benefit from a new instruction, why should the developer waste time on it?

After Intel P4 and AMD K8, speedup in video codecs mostly come from improvement in execution effeciency of "old" instruction sets.

[mandarinka]

ffdshow doesn't have its own decoding code, it uses libav or ffmpeg instead (same with lav video). That means ffmpeg/libav is where the clever gentlemen have to add optimizations for new instruction sets like AVX/XOP...

There is no such difference between processors. You had a TV vs PC levels issue in your setup that had nothing to do with the CPU.

6. 22NM in 2012 Better for ffdshow :confused:

22 nm CPUs are more energy efficient and therefore they produce less heat and less fan noise. All that is good for any application.

[nm]

ffdshow doesn't have its own decoding code, it uses libav or ffmpeg instead (same with lav video).

While that's quite true for decoding, ffdshow does have some modified or custom filters that many people use. For example its yadif implementation is patched for multithreading, which makes it usable for 1080i input on many CPUs. Yadif also got SSSE3 optimizations first in ffdshow, IIRC

[hogtop]

I'm sorry if you do not feel a difference between the sound or image processors we have a big problem
And you can not help me

There is no such difference between processors

Which audio system do you have:confused:
What screen do you have:confused:
How do you adjust encoded:confused:
I'm sorry for the questions
but your answer is far from reality

nothing to do with the CPU.
Everything to do with the processor and processing

[Asmodian]

The video will not look different depending on the CPU you have. It might decode faster/slower but nothing else should change (unless you found a bug in ffdshow/libav/ffmpeg).

Your video card could have a very small effect on video look if you are using a standard renderer (EVR/VMR9) but there is not a big difference between Nvidia and AMD atm.

3. I had the I7 920 and I sold Because black in movies was not good compared to AMD

4. lighting with live concerts with Intel was smeared and and not sharp Is it fixed today


These two statements don't make any sense.

[hogtop]

Sorry do not agree with you
If there was no difference
from Intel Developers were not dealing with video and audio commands
And no one from Intel would not have invested in developing in new Intel processors and fFDSHOW

Too bad you did not know how to use the coding on FFDSHOW
Or you know, and Intel has not made anything on FFDSHOW?
FFDSHOW WORK NOT BUD WITH AMD .
If you know how to work with FFDSHOW you know how to improve the sound
Make Stereo to Dolby Digital 2 CH up to 5.1or Dolby Pro Logic II
Or add lighting to improve the Contras movie
And much more

It might decode faster/slower but nothing else
Anything else?
Are you kidding?
That's a lot to further improve picture and sound
If you run the command that developer open on FFDSHOW
and You have a fast processor with appropriate commands

but there is not a big difference between Nvidia and AMD atm.
Say what computer you have?
What screen you have ?
What cable connections ?
You have a receiver?
I'm serious

I happen to have video cards of 2 companies
And there is a big difference
IN 570 and 470
NVIDIA picture in more natural, deeper colors
To AMD has a lot of problems at the corners of the photo gives not so good picture
Why do you think that their price so low? That they do not like money?

3. I had the I7 920 and I sold Because black in movies was not good compared to AMD

4. lighting with live concerts with Intel was smeared and and not sharp Is it fixed today

Yes it makes sense !
That was before Intel open on FFDSHOW
Command 4.1
I asked why not open a Command 4.1
On FFDSHOH
I was told in this site Command 4.1 is not Related to FFDSHOW It's about anti-virus

again Intel I7 was a Better than sound with AMD
Intel was impressive Picture with light
But the picture in the dark was a lack of focus
Live concerts lighting was not focused

@hogtop, you're either imagining things, have discovered some very unusual bugs, or are simply trolling.

Unless you can provide some concrete examples that others can reproduce, kindly stop spouting nonsense.

Number of names you write ?
Why are you addressing me impertinently?
You think I'm a friend of yours?

You have the right to ask
where you think you have the right to curse me?

Closed for rule #4 (http://forum.doom9.org/forum-rules.htm) (and maybe #11).

Also everything to be said about this topic was already said, I think.
