  • Pass UTF8 parameter in powershell

    13 juin 2018, par Dev_MC

    I have to use ffmpeg-normalize (https://github.com/slhck/ffmpeg-normalize) in my project.

    Everything works well except that encoding have trouble on Windows :

    $OutputEncoding = [System.Text.Encoding]::Unicode
    
$OutputEncoding
    
Get-WinSystemLocale
    
pause
    
Get-ChildItem -path "./" -recurse | foreach ($_) {
    
    if ($_.Extension -eq ".wav") { 
    
    write $_.FullName
    
     ffmpeg-normalize $_.FullName -nt peak -t -20 -o $_.FullName -f
    
     pause
    
    }
    
    if ($_.Extension -eq ".mp4") { 
    
     ffmpeg-normalize $_.FullName -c:a aac -nt peak -t -20 -o $_.FullName -f
    
    }

    The program works well on MacOS, so I don’t think it’s a software issue. It looks like PowerShell does not send the parameter to the program correctly.

    Do you have any ideas ?

  • Is there any way to specify streams by pid with ffmpeg, if the value of pid is duplicated ?

    22 novembre 2019, par Bo Wang

    I have a nice m2ts file and I would like to demux specific audio streams from it. Of important, this specification is needed to use PID as identifier.
    The exemplified m2ts file has 7 audio streams, which is detected by eac3to and shown below

    eac3to.exe F:\xxx 1)
