  • 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.

  • powershell output to .txt file wont print the for loop

    15 avril 2020, par ilham zacky

    I have some audio, video & jpg files.
I am using ffmpeg to get all the duration

    



    all thing works perfect, I have got all durations from a for loop and set it to a variable, when I echo it, it works perfectly, but when I output it to a .txt file it prints only the last loop
any suggestion 
below is my code

    



    $file = "D:\edl\input\aa.xlsx"
  $sheetName = "Sheet1"
  #Create an instance of Excel.Application and Open Excel file
  $objExcel = New-Object -ComObject Excel.Application
  $workbook = $objExcel.Workbooks.Open($file)
  $sheet = $workbook.Worksheets.Item($sheetName)
  $objExcel.Visible=$false
  #Count max row
  $rowMax = ($sheet.UsedRange.Rows).count
  #Declare the starting positions
  $rowName,$colName = 1,1
  $rowAge,$colAge = 1,2
  $rowCity,$colCity = 1,3
  $rowMessage,$colMessage = 1,9
  #loop to get values and store it
  for ($i=0; $i -le $rowMax-1; $i++)
  {
  $id = $sheet.Cells.Item($rowName+$i,$colName).text
  $name = $sheet.Cells.Item($rowAge+$i,$colAge).text
  $subtitle = $sheet.Cells.Item($rowCity+$i,$colCity).text
$filename2 = "$id.jpg"
$filename = "$id.mp4"
$filename1 = "$id.m4a"
$duration2 = if ((ffmpeg -i $filename2 2>&1 | Out-String) -match 'Duration:\s+([\d:.]+)') { $matches[1] };
$duration1 = if ((ffmpeg -i $filename1 2>&1 | Out-String) -match 'Duration:\s+([\d:.]+)') { $matches[1] };
$duration = if ((ffmpeg -i $filename 2>&1 | Out-String) -match 'Duration:\s+([\d:.]+)') { $matches[1] };
if($duration2){
$duration2 = "02:00:11:15"
$bb = $duration2
$out = "$i" + "  " + "AX" + "   " + "V" + "      " + "C" + "   " + "00:00:00:00" + " " + $bb + "   "+ "* FROM CLIP NAME: " + $id+".jpg"
}
if($duration1){

$out1 = "$i"+ "  " + "AX"  + "   " + "AA" + "     " + "C" + "   " + "00:00:00:00" + " " + $duration1 + "   " + "* FROM CLIP NAME: " + $id+".m4a"
}
if(!$duration){
}else{
$out2 = "$i" + "  " + "AX" + "   " + "AA/V" + "   " + "C" + "   " + "00:00:00:00" + " " + $duration + "   "+ "* FROM CLIP NAME: " + $id+".mp4"
}

$gg = $out+"`n"+"`n"+$out1+"`n"+"`n"+$out2+"`n"
echo $gg
$gg | Out-File -FilePath d:\edl\input\output.txt

  }

  #close excel file
  $objExcel.quit()


    



    when i echo variable $gg
    
this is the output

  • How to count variable in for loop in power shell

    17 avril 2020, par ilham zacky

    I am using powershell and i have got a for loop running each time 3 variables get printed, for now, loop runs 5 times. I need to get the count like $i++

    



    This is a part of my code

    



    $file = "D:\edl\input\CPExport.xlsx"
$sheetName = "Sheet1"
$objExcel = New-Object -ComObject Excel.Application
$workbook = $objExcel.Workbooks.Open($file)
$sheet = $workbook.Worksheets.Item($sheetName)
$objExcel.Visible = $false
$rowMax = ($sheet.UsedRange.Rows).count
$nu = 0
$rowcount = 000 

for ($i = 0; $i -le $rowMax - 1; $i++) {
    $id = $sheet.Cells.Item($rowName + $i, $colName).text
    $name = $sheet.Cells.Item($rowAge + $i, $colAge).text
    $subtitle = $sheet.Cells.Item($rowCity + $i, $colCity).text
    $jpgId = "$id.jpg"
    $videoId = "$id.mp4"
    $audioId = "$id.m4a"
    $duration1 = if ((ffmpeg -i $audioId 2>&1 | Out-String) -match 'Duration:\s+([\d:"."]+)') { $matches[1] };
    $duration2 = if ((ffmpeg -i $jpgId 2>&1 | Out-String) -match 'Duration:\s+([\d:"."]+)') { $matches[1] };
    $duration = if ((ffmpeg -i $videoId 2>&1 | Out-String) -match 'Duration:\s+([\d:"."]+)') { $matches[1] };

    $newduration = ("$duration").Replace(".", ":")
    $newduration1 = ("$duration1").Replace(".", ":")
    $newduration2 = ("$duration2").Replace(".", ":")

    $out1 = ""
    $out2 = ""
    $out = ""
    $nu++
    $rowcount++
    if ($newduration1) {

        if ($nu -eq 1) {
            $audioA = "00:00:00:00"
        }

        $audioB = Add-Frame -Base $newduration1 -Offset $audioA
        $out1 = "$rowcount" + "  " + "AX" + "   " + "AA" + "     " + "C" + "   " + "00:00:00:00" + " " + $newduration1 + "   " + $audioA

    }


    if ($newduration) {

        $videoA = $imageB
        $videocal = Add-Frame -Base $newduration -Offset $videoA
        $videoB = $videocal
        $out2 = "$rowcount" + "  " + "AX" + "   " + "AA/V" + "   " + "C" + "   " + "00:00:00:00" + " " + $hh + "   " + " " + $videoA 
    }
    else {
        $videoB = ""
    }
    $gg = $out1 + "`n" + "`n" + $out + "`n" + "`n" + $out2 + "`n"
    echo $gg

    $gg | Out-File -FilePath d:\edl\input\output.txt -Append

    avformat/matroskaenc : Improve mimetype search

    Use the mime_types of the corresponding AVCodecDescriptor instead of
    
tables specific to Matroska. The former are generally more encompassing :
    
They contain every item of the current lists except "text/plain" for
    
AV_CODEC_ID_TEXT and "binary" for AV_CODEC_ID_BIN_DATA.
    

    The former has been preserved by special-casing it while the latter is
    
a hack added in c9212abf so that the demuxer (which uses the same tables)
    
sets the appropriate CodecID for broken files ("binary" is not a correct
    
mime type at all) ; using it for the muxer was a mistake. The correct
    
mime type for AV_CODEC_ID_BIN_DATA is "application/octet-stream" and
    
this is what one gets from the AVCodecDescriptor.
