How do i access inputs that have been added to a command

[HaroldObasi]

Hi, if i have added some inputs to a command is there a function, or an attribute to use and see them ?

import ffmpeg from "fluent-ffmpeg";
const command = ffmpeg()

videos.forEach((video) => {
  command.addInput(video)
})

// console.log( all the input i just passed to command ?)

[HaroldObasi]

also is there a way for me to see the output of the command being by ffmpeg ?

Hello,

You can view the inputs that have been added to fluent-ffmpeg by accessing the internal _inputs array. I do not believe there is a built in method to directly list all the inputs you've added to the command. Here is how you can log them:

import ffmpeg from "fluent-ffmpeg";
const command = ffmpeg()

videos.forEach((video) => {
  command.addInput(video)
})

console.log(command._inputs.map(input => input.source));

(just to reiterate, _inputs is not part of the public API, so it could change in future versions)

To see the full FFmpeg command being run you can use the .on('start', ...) event to inspect the command line that ffmpeg is executing

command
  .on('start', (cmdLine) => {
    console.log('FFmpeg command:', cmdLine);
  })
  .save('output.mp4'); // or whatever output you're using
