  • Installation en mode ferme

    4 février 2011, par

    Le mode ferme permet d’héberger plusieurs sites de type MediaSPIP en n’installant qu’une seule fois son noyau fonctionnel.
    C’est la méthode que nous utilisons sur cette même plateforme.
    L’utilisation en mode ferme nécessite de connaïtre un peu le mécanisme de SPIP contrairement à la version standalone qui ne nécessite pas réellement de connaissances spécifique puisque l’espace privé habituel de SPIP n’est plus utilisé.
    Dans un premier temps, vous devez avoir installé les mêmes fichiers que l’installation (...)

  • Installation en mode standalone

  • Linphone OSx msx264 encryption VGA takes 97% CPU, why ?

    11 septembre 2013, par Maxim Shoustin

    I have problem and today don't know how to fix it or even from where to start.

    I have Linphone application that uses msx264 plugin.

    All stuff I run on OSx and my ffmpeg version installed from port , I didn't using selfupdate for port

    bash-3.2# port installed ffmpeg-devel
    

    
The following ports are currently installed:
    
 ffmpeg-devel @20130205_0+gpl2
    
 ffmpeg-devel @20130328_0 (active)
    
 ffmpeg-devel @20130328_0+gpl2

    So I compiled and build msx264, no errors.

    Now I try to send video over CIP resolution VGA (640x480) and get huge delay 8-9 seconds, even self-view I see in big delay.

    when I configure CIF (352x288), all seems fine.

    It's really strange that self-view camera has delay 4-5 sec.

    So from logs during the session I found that msx264 plugin takes 97% CPU

    On PC (windows 7) the same code runs fine, even HD I don't see any problems.

    What is the problem should be ?

    Please, help me to find the problem.

  • Noobs approach to automate x264 cmd

    16 novembre 2012, par nightcrawler

    so here is my script to loop through specific video extensions » add a manual profile » generate necessary *.bat & finally a final 'loader' batch file to execute previous *.bat files sequentially & necessary logging (this gives quiet a deal of freedom if you so want)

    ::==
    
:: gets lines into vars c1 v2 v...
    
@echo off
    
:: user input required
    
cd /d "d:\Trainers\out\"
    
setLocal EnableDelayedExpansion
    
dir /B /O:N | findstr ".wmv$ " >filename.txt
    
echo. >log.txt
    
:: user input required
    
for /f "tokens=* delims= " %%a in ('type filename.txt ^|findstr ".wmv$"') do (
    
set /a n+=1
    
echo. >file!n!.bat
    
set in=%in%%%a
    
:: user input required
    
set out=!in:.wmv=.mp4!
    
:: user input required
    
set v=x264 --crf 23  --level 3.1 --tune film -o "d:\Trainers\out\!in!" "d:\Trainers\out\!out!"
    
echo. !v!>file!n!.bat
    
)
    
dir /B /O:N | findstr ".bat$ " >x264_home.txt
    
for /f "tokens=* delims= " %%a in (x264_home.txt) do (
    
set /a n+=1
    
:: mtee is an external library Google it
    
set "z=call %%a | mtee /d/c/t/+ log.txt"
    
echo. !z! >> x264_home.bat
    
)
    
echo. @echo off > newFile.bat
    
type x264_home.bat >> newFile.bat
    
type newFile.bat > x264_home.bat
    
del newFile.bat,x264_home.txt,filename.txt
    
echo. pause >> x264_home.bat
    
echo. @echo All Operation done... >> x264_home.bat
    
:: user input required
    
move "d:\Trainers\out\*.bat" "d:\Program Files\x264_auto\test\"
    
:: user input required
    
move "d:\Trainers\out\log.txt" "d:\Program Files\x264_auto\test\"
    
::==

    Now the above code which is fairly easy to understand (bcz its written by a noob) run perfectly & create necessary files. For instance one of the file1.bat looks like this :

    x264 --crf 23  --level 3.1 --tune film --preset veryslow --deblock -2:-1 --zones 24233,25324,q=20 --acodec aac --abitrate 80 -o "d:\Trainers\out\1.wmv" "d:\Trainers\out\1.mp4"

    ...& the loader .bat file looks like

     @echo off 
    
 call file1.bat | mtee /d/c/t/+ log.txt 
    
 call file2.bat | mtee /d/c/t/+ log.txt
    
 call file3.bat | mtee /d/c/t/+ log.txt
    
 @echo All Operation done...

    You see this is a quiet flexible approach in that you can use special filestr » set another loop » set another profile. Furthermore every batch file can be latter edited especiialy when you heavily use --zone x264 feature
    I am successful because there is no error in any output ...but its the x264.exe (provider/compiler x264GUI) throws error which it otherwise don't ?

    d:\Program Files\x264_auto\test>x264 --crf 23  --level 3.1 --tune film --preset
    
veryslow --deblock -2:-1 --zones 24233,25324,q=20 --acodec aac --abitrate 80 -o
    
"d:\Trainers\out\1.wmv" "d:\Trainers\out\1.mp4"
    
ffms [error]: could not create index
    
lavf [error]: could not open input file
    
raw [error]: raw input requires a resolution.
    
x264 [error]: could not open input file `d:\Trainers\out\1.mp4' via any method!

    its the x264 thats the culprit perhaps a senior guide is required here
