  • How to run a ffmpeg command in Powershell and pass variables to it ?

    22 avril 2021, par lucullus

    I would like to run the following command in Powershell :
ffmpeg -i "VIDEO.mp4" -i "AUDIO.m4a" -c copy -map 0:v:0 -map 1:a:0 "OUTPUT VIDEO.mp4"

    


    But I would like to browse for the files. I have tried this :

    


    Add-Type -AssemblyName System.Windows.Forms 

$VideoBrowser = New-Object System.Windows.Forms.OpenFileDialog -Property @{ 
    InitialDirectory = $PSCommandPath
    Filter = 'Video file (*.mp4)|*.mp4|All files (*.*)|*.*'
    Title = 'Choose video file'
}
$null = $VideoBrowser.ShowDialog()
if (!($VideoBrowser.FileName))
{
    return
}

$AudioBrowser = New-Object System.Windows.Forms.OpenFileDialog -Property @{ 
    Filter = 'Video file (*.m4a)|*.m4a|All files (*.*)|*.*'
    Title = 'Choose audio file'
    RestoreDirectory = $true
}
$null = $AudioBrowser.ShowDialog()
if (!($AudioBrowser.FileName))
{
    return
}

$NewVideoBrowser = New-Object System.Windows.Forms.SaveFileDialog -Property @{ 
    Filter = 'Video file (*.mp4)|*.mp4|All files (*.*)|*.*'
    Title = 'Save new video file as'
    RestoreDirectory = $true
}
$null = $NewVideoBrowser.ShowDialog()
if (!($NewVideoBrowser.FileName))
{
    return
}


    


    And all these ways to run the command but all fail :

    


    $ArgumentList = '"{0}" -i "{1}" -c copy -map 0:v:0 -map 1:a:0 "{2}"' -f $VideoBrowser.FileName, $AudioBrowser.FileName, $NewVideoBrowser.FileName;
Start-Process -FilePath ffmpeg.exe -ArgumentList $ArgumentList -Wait -NoNewWindow


    


    OR

    


    $ArgumentList = '"' + $VideoBrowser.FileName + '" -i "' + $AudioBrowser.FileName + '" -c copy -map 0:v:0 -map 1:a:0 "' + $NewVideoBrowser.FileName + '"'
Start-Process -FilePath ffmpeg.exe -ArgumentList $ArgumentList -Wait -NoNewWindow


    


    OR
ffmpeg.exe $VideoBrowser.FileName -i $AudioBrowser.FileName -c copy -map 0:v:0 -map 1:a:0 $NewVideoBrowser.FileName

    


    What should I try ?

  • How is the AAC encoder priming delay handled in HLS ?

    6 décembre 2022, par muraliv

    As per Apple, in AAC encoding 2112 priming samples are added at the beginning of audio. When creating HLS stream with AAC audio, will these priming samples be added to the beginning of each HLS segment or only to the first HLS segment ? And, how does this AAC encoder delay affect HLS DISCONTINUITY tags later in the HLS stream ?
