  • 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
    
    }
    
        if ($_.Extension -eq ".mp3") { 
    
     ffmpeg-normalize $_.FullName -c:a libmp3lame -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)
    
M2TS, 1 video track, 7 audio tracks, 5 subtitle tracks, 1:40:03
    
1: Chapters, 34 chapters
    
2: h265/HEVC, 2160p24 /1.001 (16:9), 10 bits
    
3: TrueHD/AC3 (Atmos), English, 7.1 channels, 48kHz, dialnorm: -28dB
    
   (embedded: AC3, 5.1 channels, 640kbps, 48kHz, dialnorm: -27dB)
    
4: E-AC3, English, 7.1 channels, 1024kbps, 48kHz, dialnorm: -28dB
    
   (core: AC3, 5.1 channels, 576kbps, 48kHz, dialnorm: -28dB)
    
5: AC3, English, 5.1 channels, 640kbps, 48kHz, dialnorm: -27dB
    
6: AC3, English, 2.0 channels, 320kbps, 48kHz, dialnorm: -27dB
    
7: AC3, English, 2.0 channels, 320kbps, 48kHz, dialnorm: -27dB
    
8: AC3, Chinese, 2.0 channels, 448kbps, 48kHz
    
9: AC3, Chinese, 5.1 channels, 384kbps, 48kHz, 300ms
    
10: Subtitle (PGS), English
    
11: Subtitle (PGS), Chinese
    
12: Subtitle (PGS), Chinese
    
13: Subtitle (PGS), Chinese
    
14: Subtitle (PGS), Chinese

    However, if I run
    ffmpeg.exe -hide_banner -i "F:\xxx\BDMV\STREAM\00055.m2ts", ffmpeg shows an additional audio stream as it recognizes the embedded 5.1 AC3 stream inside the 7.1 TrueHD audio stream, as independent :

    Input #0, mpegts, from 'F:\xxx\BDMV\STREAM\00055.m2ts':

    Stream #0:13[0x12a4]: Subtitle: hdmv_pgs_subtitle ([144][0][0][0] / 0x0090)

    It can be found that the Stream #0:1 and Stream #0:2 have the same PID 0x1100. And ffmpeg.exe -hide_banner -i "F:\xxx\BDMV\STREAM\00055.m2ts" -map i:0x1100 -c copy 00055-0x1100.thd will yield error :

  Stream #0:1 -> #0:0 (copy)
    
  Stream #0:2 -> #0:1 (copy)

    By contrast, it works by giving other pids without duplication, such as ffmpeg.exe -hide_banner -i "F:\xxx\BDMV\STREAM\00055.m2ts" -map i:0x1101 -c copy 00055-0x1101.eac3 :
