Using Video Recordings in Vuforia ARCamera
2 juillet 2023, par Chengyuan QianI am trying to test Vuforia on some pre-recorded videos in a Unity project. However, I found that I can only use videos recorded by the Vuforia SessionRecorder. When I use video recorded by other apps or devices, even though its resolution, frame rate and encoding type are all the same as the Vuforia's sample recordings, I still get the following error,


Failed to start Vuforia
UnityEngine.Debug:LogError (object)
Vuforia.Internal.Utility.UnityLogger:LogError (string)
Vuforia.Internal.Utility.Log:Error (string)
Vuforia.Internal.Core.Engine:Start (System.Action)

Vuforia.Internal.Core.Engine:add_OnAfterVuforiaInitializedPublic (System.Action`1)
Vuforia.VuforiaBehaviour:Awake ()




In addition to make sure the resolution, frame rate and encoding type the same, I used ffmpeg to check the metadata of Vuforia SessionRecorder's recordings and my own recordings, but I have no idea which property makes the difference. Below are the metadata of the two videos,

Have an error running one PowerShell script to concatenate avi files, when a very similar script works fine
1er juillet 2023, par hw22sWhen 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 {
 $process = Start-Process -FilePath "ffmpeg" -ArgumentList $concatArguments -NoNewWindow -PassThru -Wait -ErrorAction Stop
 Write-Host "Concatenation complete. Output file: $outputFile"
 } catch {
 Write-Host "Error occurred while executing FFmpeg command:"
 Write-Host "Error message: $($_.Exception.Message)"
 }
} else {
 Write-Host "Not enough AVI files found in the folder for concatenation."
}



Output with error, (and no concatenated file is actually produced, needless to say) :


Input Files for Concatenation:
webcam0.avi
webcam1.avi

But this script, which ostensibly does the same thing to the same files, works fine :

$outputFile = "C:\Users\HomePC\hswlab\Desktop\videos\eyeblink\022223\2023_04_24\16_15_23\My_WebCam\concat.avi" # Path to the output concatenated video file

# Create a temporary batch script
$batchScriptPath = [System.IO.Path]::GetTempFileName() + ".bat"
@'
@echo off
ffmpeg -i "%~1" -i "%~2" -filter_complex "[0:v][1:v]concat=n=2:v=1[outv]" -map "[outv]" "%~3"

# Execute the temporary batch script
try {

 Write-Host "Concatenation complete. Output file: $outputFile"
} catch {
 Write-Host "Error occurred while executing FFmpeg command:"
 Write-Host $_.Exception.Message
}

# Remove the temporary batch script
Remove-Item -Path $batchScriptPath -Force



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 ?
