  • Encoding AV1 to h264 error : Assertion pkt failed at D :/code/ffmpeg/src/fftools/ffmpeg_dec.c:518 [closed]

    1er mars, par KyonGiang

    I used below code to convert from AV1 to x264 mp4, and I got error message : "Assertion pkt failed at D :/code/ffmpeg/src/fftools/ffmpeg_dec.c:518"

    


    ffmpeg -i input.mp4 -c:v h264_nvenc -c:a copy output.mp4 


    


      

    • I'm using Windows 10 64b, Command Prompt, ffmpeg version 2024-01-20-git-6c4388b468-full_build-www.gyan.dev

      • 


    


    I removed h264_nvenc, Run as Administrator but the result is same.

    


    ffmpeg -i input.mp4 -c:v -c:a copy output.mp4

    


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

    10 janvier, 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.

    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.
