• Invalid frame dimension, invalid data found when processing input, muxing overhead : unknown when concatting old VOB files | FFMPEG

  9 mars 2023, par Victor Hartman

  I am dealing with multiple errors which I am not able to resolve. I am trying to concat 4 old VOB files to a mp4. Using command (already solved a 'pts has no value error') :

  


  .\ffmpeg.exe -fflags +genpts -f concat -i .\files.txt -c copy output.mp4


  


  files.txt looks like this :

  


  file 'VTS_01_1.VOB'
file 'VTS_01_2.VOB'
file 'VTS_01_3.VOB'
file 'VTS_01_4.VOB'


  


  Output looks like this :

• Have an error running one PowerShell script to concatenate avi files, when a very similar script works fine

  1er juillet 2023, par hw22s

  When I run the following PowerShell script, to concatenate the .avi files in a folder, I get an error.

  


  Script :

  


  # Set the folder path where the AVI files are located
$folderPath = "C:\Users\HomePC\hswlab\Desktop\videos\eyeblink\022223\2023_04_24\16_15_23\My_WebCam"

# Get all AVI files in the folder
$aviFiles = Get-ChildItem -Path $folderPath -Filter "*.avi" | Sort-Object Name

# Check if there are at least 2 AVI files for concatenation
if ($aviFiles.Count -ge 2) {
    $videoFiles = $aviFiles.FullName

    Write-Host "Input Files for Concatenation:"
    foreach ($file in $aviFiles) {
        Write-Host $file.Name
    }

    $outputFile = Join-Path -Path $folderPath -ChildPath "concatenated.avi"

    # Create the FFmpeg command for concatenation
    $concatArguments = "-f", "concat", "-i", "`"concat:$videoFiles`"", "-c", "copy", "`"$outputFile`""

    $command = "ffmpeg $concatArguments"
    Write-Host "FFmpeg Command: $command"

    try {

} else {
    Write-Host "Not enough AVI files found in the folder for concatenation."

  I can't figure out what is wrong with the first script. I tried many variations of the first script but cannot get it to work.

  


  Any help ?

  


• Multiple format changes in FFmpeg for thermal camera

  6 février 2023, par Greynol4

  I'm having trouble generating a command to process output from a uvc thermal camera's raw data so that it can be colorized and then output to a virtual device with the intention of streaming it over rtsp. This is on a raspberry pi 3B+ with 32bit bullseye.

  


  The original code that works perfectly for previewing it is :

  


  ffmpeg -input_format yuyv422 -video_size 256x384 -i /dev/video0 -vf 'crop=h=(ih/2):y=(ih/2)' -pix_fmt yuyv422 -f rawvideo - | ffplay -pixel_format gray16le -video_size 256x192 -f rawvideo -i - -vf 'normalize=smoothing=10, format=pix_fmts=rgb48, pseudocolor=p=inferno'


  


  Essentially what this is doing is taking the raw data, cutting the useful portion out, then piping it to ffplay where it is seen as 16bit grayscale (in this case gray16le), then it is normalized, formatted to 48 bit rgb and then a pseudocolor filter is applied.

  


  I haven't been able to get this to translate into ffmpeg-only because it throws codec errors or format errors or converts the 16bit to 10bit even though I need the 16bit. I have tried using v4l2loopback and two instances of ffmpeg in separate windows to see if I could figure out where the error was actually occuring but I suspect that is introducing more format issues that are distracting from the original problem. The closest I have been able to get is

  


  ffmpeg -input_format yuyv422 -video_size 256x384 -i /dev/video0 -vf 'crop=h=(ih/2):y=(ih/2)' -pix_fmt yuyv422 -f rawvideo /dev/video3

  


  Followed by

  


  ffmpeg -video_size 256x192 -i /dev/video3  -f rawvideo -pix_fmt gray16le -vf 'normalize=smoothing=10,format=pix_fmts=rgb48, pseudocolor=p=inferno' -f rawvideo -f v4l2 /dev/video4

  


  This results in a non colorized but somewhat useful image with certain temperatures showing as missing pixels as opposed to the command with ffplay where it shows a properly colorized stream without missing pixels.

  


  I'll include my configuration and log from the preview command but the log doesn't show errors unless I try to modify parameters and presumably mess up the syntax.

  


   ffmpeg -input_format yuyv422 -video_size 256x384 -i /dev/video0 -vf 'crop=h=(ih/2):y=(ih/2)' -pix_fmt yuyv422 -f rawvideo - | ffplay -pixel_format gray16le -video_size 256x192 -f rawvideo -i - -vf 'normalize=smoothing=10, format=pix_fmts=rgb48, pseudocolor=p=inferno'

  I'd also like to use the correct option so it isn't scrolling though every frame in the log as well as links to resources for adapting a command to a script for beginners even though that's outside the purview of this question so any direction on those would be much appreciated.
