• ffmpeg errors when playing a playlist - Non monotonous DTS

  20 novembre 2023, par Evilmachine

  i have a strange bug in ffmpeg. I am using ffmpeg to stream Twitch VODs and CLIPs to a 24/7 twitch channel. If i stream the files one by one its working. If i am streaming a playlist containing vods and clips i get this error when the shorter clips are playing :

  


  [flv @ 0x555677050c60] Non-monotonous DTS in output stream 0:0; previous: 56867, current: 31846; changing to 56867. This may result in incorrect timestamps in the output file.

  


  and the video stops. Once the playlist has a longer vod again it is working.

  


  here is my code that i use to stream :

  


  while [ 1 -eq 1 ]
do
ffmpeg  -fflags +igndts -re -f concat -safe 0 -i playlist.txt -codec copy -flvflags no_duration_filesize -f flv rtmp://XXXXXXXXX
done


  


  If i look into ffprobe the files seems both to be normal :

  


  VODs

  Has someone a hint why this error happens and how i can avoid them ?
Is gstreamer better for this approach ?

  


  Thanks a lot in Advance.

  


  I tried changing the files.

• 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.

  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.
