• Line 1 : unknown keyword ' file' ffmpeg

  6 janvier 2024, par pops64

  I am trying to run a concation of multiple files using ffmpeg. Followed directions in docs and getting

  


  Line 1: unknown keyword 'file'
[in#0 @ 000001b09b25e840] Error opening input: Invalid data found when processing input
Error opening input file mylist.txt.
Error opening input files: Invalid data found when processing input


  


  I am not sure what is going wrong. The text file appears to be in the correct format.

  


  $clips = Get-ChildItem -Path Y:\****\Test -File -Filter "*.mp4"
$regex = "(?:\w+)-(?:[i]+-)?(?\d+)-(?\d+)-(?:\w+)"
$groupedScenes = $clips | Group-Object {[regex]::Match($_.Name, $regex).Groups["scene_id"].value}
foreach($scene in $groupedScenes)
{
    $sortedScene = $scene.Group | Sort-Object {[regex]::Match($_.Name, $regex).Groups["clip_id"].value -as [int]} 
    foreach($i in $sortedScene) 
    {
        "file 'Y:\*****\Test\$i'" | Out-File mylist.txt -Encoding utf8 -Append
    }
    .\ffmpeg.exe -f concat -safe 0 -i mylist.txt -map 0 -c:v hevc_amf -quality quality -rc cqp -qp_p 26 -qp_i 26 -c:a aac -b:a 128K -y Y:\*****\Test\Procssed\$sortedScene.mp4

• Possible issue / unknown "feature" of ffmpeg ? [closed]

  23 septembre 2023, par Grumpy OldMan

  I'm using ffmpeg to split up a MP4 file into shorter (about 5 seconds) files, each of which I will then later add hard-coded captions to.

  


  ffmpeg -i master.mp4 -ss 00:00:00 -t 00:00:05 -c:v copy -c:a copy x-01.mp4


  


  It seems that if there is SRT file with the same base name as the output file (i.e. 'x-01.srt' in the above example), captions will be added to it. This is not what I was wanting. My workflow is to add it at a later stage. Is this an intended feature of the software or did I accidentally discover some sort of unintended side effect ?

  


  I've tried searching the web, but can't find any mention of the "feature". If I change the ffmpeg command to use an output file name that does not have an associated ".srt" file with the same name, it works as expected.

  


• Unknown encoder 'libx264' in flutter android app

  17 juillet 2023, par ololo

  I am trying to use libx264 via ffmpeg_kit_flutter with full-gpl options in my Flutter app. However, when I start the app on Android, I keep getting the error :

  


  "Unknown encoder 'libx264'."

  


  Here is my current setup :

  


  In android/build.gradle file :

  


  buildscript {
    ext {
        ffmpegKitPackage = "full-gpl" // Notice I specified the option here
        kotlin_version = '1.8.0'
    }

    repositories {
        google()
        mavenCentral()
    }
    // .....
}


  


  In android/app/build.gradle file :

  


  android {
    compileSdkVersion 33

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }

    packagingOptions { 
        // I specified the libx264 in this packageOptions block
        pickFirst 'lib/x86_64/libx264.so'
        pickFirst 'lib/arm64-v8a/libx264.so'
        pickFirst 'lib/armeabi-v7a/libx264.so'
        pickFirst 'lib/x86/libx264.so'
    }
}


  


  In pubspec.yaml file :

  


  dependencies:
  ffmpeg_kit_flutter: ^5.1.0


  


  What could be the issue causing the "Unknown encoder 'libx264'" error ? Any help would be appreciated. Thank you !
