• Why is the external executable I bundled with my azure function not being found at runtime, despite it being present in the expected location ?

  6 septembre 2023, par Cristian Camilo Garcia Barrera

  I have a group of Azure functions that I publish to a functions app. One of these is a blob triggered function, meant to extract thumbnails from videos uploaded to Azure storage, and to do so, uses ffmpeg.exe.

  


  I have published the project via Visual Studio, adding the executable in a directory in the root of the project. The relative path is exe/ffmpeg.exe. To include the executable in the published bundle I followed the instructions in this Microsoft Developer instructional video.

  


  After publication, If I enter the Kudu debug console for this function app, I can find the file under C:\home\site\wwwroot\exe\ffmpeg.exe, as expected. I can even use that absolute path to execute ffmpeg inside the Kudu console.

  


  This is the code I use to call the ffmpeg executable in the blob function :

  


  using (var process = new Process())
{
    process.StartInfo = new ProcessStartInfo
    {
        FileName = @"C:\home\site\wwwroot\exe\ffmpeg.exe",
        Arguments = $"-hide_banner -loglevel error -i {videoTempPath} -frames:v 1 {thumbTempPath}",
        UseShellExecute = false,
        RedirectStandardOutput = true,
        RedirectStandardError = true,
        CreateNoWindow = true
    };

    process.Start();
    await process.WaitForExitAsync();
}


  


  However, this does not work. I get the following error in the logs :

  


  


  An error occurred trying to start process 'C :\home\site\wwwroot\exe\ffmpeg.exe' with working directory 'C :\Program Files (x86)\SiteExtensions\Functions 4.25.2132bit. The system cannot find the file specified.

  


  


  And indeed my thumbnails are never created. How can I solve this, or why does it happen ?

  Refactor tx_block_rd_b() to compute per block rd cost

  This commit makes the tx_block_rd_b() compute the rate and
  distortion cost per transform block, instead of accumulating these
  costs.
