  Fate tests pass with both avresample as well as swresample based opus decoder, but
  
  are disabled (reference files are very large so i want to think a day or 2 about
  
  if theres an alternative or if they could be avoided, they also dont match the
  
  official samples)

• Node 18 or Node 20 break ffmpeg (in google cloud functions -> ffprobe was killed with signal SIGSEGV)

  10 janvier 2024, par user20206929

  Please see below, the code is working on node js 16, but not when upgrading to node 18 or 20.

  


  const ffmpeg = require("fluent-ffmpeg");

// Following is inside a .https.onRequest Google Cloud function with enough memory

try {
  const duration = new Promise((resolve, reject) => {
  ffmpeg.ffprobe(videoUrl, async (err, metadata) => {
    if (err) {
      if (res.headersSent) {
        console.error("Response already sent");
        return;
      } else {
        console.log("Metadata:", metadata);
        console.log("err: " + err);
        res.status(400).send("Error getting video metadata");
        return;
      }
    }
  const duration = metadata.format.duration;
  console.log("video duration in second: " + duration);
  resolve(duration);
  });
});
  videoDuration = await duration;
} catch (err) {
  console.log(err);
  throw err;
}


  


  When upgrading to node 18/20 (No other change than upgrading node), the error "ffprobe not found" appears.

  


  But setting the path manually using ffmpeg.setFfprobePath(ffprobePath) ;
trigger the error : Error : ffprobe was killed with signal SIGSEGV

  


  So it seem its a permissions issue.

  


  However, I tried a lot of different solutions, none of them made this work.
For instance i tried to download manually the ffprobe from the official website https://ffbinaries.com/downloads. Then manually add it to the code.

  


  I tried to use https://www.npmjs.com/package/@ffprobe-installer/ffprobe or others package like https://www.npmjs.com/package/ffprobe-static

  


  I also tried to download the ffprobe file to the temporary folder of google cloud, and change the permission of this folder.

  


  All of those was doing the same error.

  


  None of what i could think of made any difference.

  


  Please help because i need to update node 16 to 18 or 20 before google remove node 16 on january 31 2024 and for now i don't see a solution.

  


  I also looked for other solution to get this duration from a video file url, but using ffmpeg seem to be the only one that should work out of the box. As it is working on node 16.

  


  Thank you,

  


  UPDATE - 11/26/2023

  


  GCP Functions NodeJS 16 runtime uses Ubuntu 18.04 with FFMpeg installed.
NodeJS 18/20 use Ubuntu 22.04, and Google decided not to include FFMpeg.

https://cloud.google.com/functions/docs/reference/system-packages

  


  No workaround or solutions found as of now

  


  UPDATE - 01/10/2024

  


  Google added back ffmpeg to latest version, this is working as before now.

  


• add libaribb24 ARIB STD-B24 caption decoder

  14 janvier 2019, par Jan Ekström

  add libaribb24 ARIB STD-B24 caption decoder
  * Outputs ASS lines with basic coloring and font scaling for each
  
    given region.
  
  * Sets the default style to the resolution of the subtitle plane
  
    (for example, 960x540 / 36pt font for profile A).
  
  * Has options to :
  
    * Disable ruby text (which is coded as regions which have
  
      half-height text in libaribb24).
  
      Enabled by default as without positioning ruby text only
  
      confuses as it is usually coded in the beginning of the decoded
  
      subtitle line.
  
    * Set the working directory, in which libaribb24 will read
  
      configuration as well as into which it may save broadcast extra
  
      symbols as PNG.
  
      Unset by default.
  The unconventional library check can be explained by the library's
  
  current master branch being licensed as LGPLv3, but at the time of
  
  writing the latest official release is still licensed under GPLv3.
  Thus, one either has to wait for the following release, or enable
  
  GPLv3.
