when encoding audio file output file has very distinguishable click (sound of the click) in the beginning. i found out it disappears when i uncheck 'normalize peeks'. is there a solution for using normalize?

owais · 16th August 2009, 21:29

guys what is the latest version? i m having build 1051, is this the latest one?

p.s i just went to megui sourceforge bla bla there was 1053

megui hasn't updated anything in a while, don't know what's up

Hi,

Not sure if i should ask this here or in the AVC forum, but anyway;

I've been wondering if it's "normal" that when thread input is set to "0" (auto), my cpu (q9450 @ 3.4GHz) usage
never reaches 100%, but fluctuates between 65% and 97%, with ~75% being the average.

I seem to remember that when i had a dualcore cpu (E6600), cpu usage always was at 100% when encoding.

I don't think avisynth is bottlenecking anything, because i don't use cpu intensive filters or such.
Here's an example of a script i might use:

Code:

# Set DAR in encoder to 37 : 20. The following line is for automatic signalling
global MeGUI_darx = 37
global MeGUI_dary = 20
DGDecode_mpeg2source("Y:\MOVIES\Absence of Malice (1981) PAL DVD\VIDEO_TS\VTS_02_1.d2v", info=3)
ColorMatrix(hints=true, threads=0)
crop( 10, 12, -10, -16)
Undot() # Minimal Noise

I've been doing some testing and i've noticed, that when i manually change the thread input to something higher
than 6 threads, cpu usage goes up and so does fps encoding rate.
I need to at least set threading to 10 or 12 to fully saturate the cpu.

For example, using the above script to encode a pal dvd with:

- unrestricted 1 pass const. quality HQ
- tuning = film
- CRF18
- threads=0
- otherwise default settings

Code:

program --profile high --preset fast --tune film --crf 18 --thread-input --deblock -1:-1 --b-adapt 2 --b-pyramid 
--ref 5 --no-mbtree --me umh --subme 6 --partitions all --trellis 2 --output "output" "input"

encoding speed is ~20.5 fps.

However, if i manually set threads=10, i get 99-100% cpu usage and ~26.8 fps, which is a ~30% speedup.

I've searched around to find more information regarding threading and cpu usage, especially with quadcore cpu's without hyperthreading, but
haven't found conclusive information, so i'm still wondering if this is "normal" or not.
I thought leaving threading at 0 (auto), which in my case would make 6 threads ( 4x 1.5) would be the best, but this doesn't seem to be the case.

Are there any "important" downsides to me upping the threading to 10 or 12 to saturate my cpu?
Are there folks with a quadcore cpu who get 100% cpu usage and max encoding speed with threads set to auto?

(Btw, i'm using the latest megui and x.264, avisynth 2.5.8, ffdshow beta6 rev 2527)

strange errors with 1053

ztomic · 17th August 2009, 01:20

Code:

--[NoImage] Standard error stream: C:\Program Files\megui\tools\x264\x264.exe: unrecognised option `--no-mbtree'

Just installed megui and got this error on first job try. Fixed with x264 r.1206 downloaded from sharktooth-- see post http://forum.doom9.org/showthread.php?t=89979

Please

and samples (short samples is enough).

owais · 17th August 2009, 02:05

i m alive !!!

but i hav seen latest version of x264 1210

SacredCultivator · 17th August 2009, 09:27

Just wondering... with the new patches for x264(1210), mkvmerge(2.9.8), nicaudio(2009-08-12), anyone NOT able to update to the latest?

When I try to update those three I get:
---
Updating x264. File 1/3.
Updating mkvmerge. File 2/3.
Updating nicaudio. File 3/3.
Update completed.
0 file was completed successfully
3 files had problems.
---

---
EDIT:
Nevermind, seemed to have fixed itself after trying again.

I'm not sure what has happened to the original megui update servers but they have not been updated for a while. i'm using a server kurtnoise mentioned somewhere in this thread, you can add it by going to the settings then

extra config -> configure servers

delete what you have and add

http://kurtnoise.free.fr/MeGUI/

I'm not sure on how upto date it is with the various programs but it is picking up 0.3.1.1053 as the latest version.

That link is for experimental version. The 'official' version is still unchanged.

will i need a codec pack installed before i install meGui?

no, just install Avisynth, ffdshow tryout and Haali Splitter and you should be fine.

nurbs · 18th August 2009, 21:31

No, in fact it's not recommended to install codec packs. It might be helpful if you installed ffdshow.

edit:
Late again. I agree with everything St Devious said.

chuck67 · 19th August 2009, 03:17

ok thank u guys for ur help.

Rodger · 20th August 2009, 00:27

I found a bug! But it has to be added recently?!
I´m sure otherwise I´d have it noticed quicker.

See the video HERE for what I mean.

I'm processing an BD mpeg2 stream and the ffdshow video setting gives 2 choices for the codec, libmpeg2 or libavcodec.

I've done a search and can't find info on which one is preferred. They both work, however in the video preview libav starts the video a a few frames later, with a pixelated screen (still). Once play is started it's fine. I don't know if that's significant, so thought I'd ask here which one to use?
