Version information

  • fluent-ffmpeg version: 2.1.3
  • ffmpeg version: 7.1
  • OS: Mac OS

Code to reproduce

// This doesn't work
const inputReadStream = fs.createReadStream(`input.ogg`);
const outputWriteStream = fs.createWriteStream(`output.ogg`);

ffmpeg(inputReadStream)
   .inputFormat("ogg")
   .setStartTime(400)
   .outputFormat("ogg")
   .on("start", () => {
      console.log("Processing....");
   })
   .on("error", (err: any) => {
      console.error("An error occurred: " + err.message);
   })
   .on("end", () => {
      console.log("Processing finished !");
   })
   .pipe(outputWriteStream, { end: false });

// This works!
const outputWriteStream = fs.createWriteStream(`output.ogg`);

ffmpeg("input.ogg")
   .inputFormat("ogg")
   .setStartTime(400)
   .outputFormat("ogg")
   .on("start", () => {
      console.log("Processing....");
   })
   .on("error", (err: any) => {
      console.error("An error occurred: " + err.message);
   })
   .on("end", () => {
      console.log("Processing finished !");
   })
   .pipe(outputWriteStream, { end: false });

(note: if the problem only happens with some inputs, include a link to such an input file)

Expected results & Observed results

I want to trim the audio starting from 400 seconds to the end. It seems that FFmpeg does not work when using an input stream, but it functions properly with an input file path. It's strange that it can cut the audio by a few seconds (like 3-4 seconds) but not by 400 seconds and no errors appear.

Here's the result
With stream:
input.ogg
image

output.ogg (4 seconds was cut)
image

Without stream:
input.ogg
image

output.ogg (Cut correctly)
image

PS.

This is an example code to reproduce the bug. In my use case, I need to read the input file from AWS S3, then pass it to FFMPEG to cut the audio before uploading it again.

So, It's important to give an input as a stream input to FFMPEG.

Checklist

  • I have read the FAQ
  • I tried the same with command line ffmpeg and it works correctly (hint: if the problem also happens this way, this is an ffmpeg problem and you're not reporting it to the right place)
  • I have included full stderr/stdout output from ffmpeg

I've tried with .wav file and It works! I think it just happen with .ogg

    const inputReadStream = fs.createReadStream(`input.wav`);
    const outputWriteStream = fs.createWriteStream(`output.wav`);

    ffmpeg(inputReadStream)
      .inputFormat("wav")
      .setStartTime(400)
      .outputFormat("wav")
      .on("start", () => {
        console.log("Processing....");
      })
      .on("error", (err: any) => {
        console.error("An error occurred: " + err.message);
      })
      .on("end", () => {
        console.log("Processing finished !");
      })
      .pipe(outputWriteStream, { end: false });

Seems like it has errors but the audio was trimmed correctly.
