• fluent-ffmpeg error : ffmpeg exited with code 1 : At least one output file must be specified

  18 septembre 2023, par 김동환

  I'm trying to create a simple video from several images on node js.

  


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

ffmpeg().input('input.txt')
.inputOption(["-f concat"])
.outputOptions("-c:v libx264 -r 30 -pix_fmt yuv420p")
.output('output.mp4')
.on('start', (commandLine) => {
console.log(`FFmpeg command: ${commandLine}`);
})
.on('end', () => {
console.log('completed');
}).on('error', (err) => {
console.error('error occurred: ' + err.message);
}).run();


  


  and input.txt is

  


  file 'test1.png'
duration 2
file 'test2.png'
duration 30
file 'test3.png'
duration 4


  


  I don't know why but this code doesn't work. but if i copy and paste the code from $commandLine, it works !!??

  


  PS C:\\Users\\donghwan\\Documents\\GitHub\\create_video\\src\> node test.js
FFmpeg command: ffmpeg -f concat -i input.txt -y -c:v libx264 -r 30 -pix_fmt yuv420p output.mp4
error occurred: ffmpeg exited with code 1: At least one output file must be specified

PS C:\\Users\\donghwan\\Documents\\GitHub\\create_video\\src\> ffmpeg -f concat -i input.txt -y -c:v libx264 -r 30 -pix_fmt yuv420p output.mp4
ffmpeg version 2023-08-20-git-f0b1cab538-full_build-www.gyan.dev Copyright (c) 2000-2023 the FFmpeg developers

and so on...


  


  I'm so confused and i tried to find any other reason for this but i couldn't find anything.

  


• Live stream failed on Youtube

  20 septembre 2023, par kuldeep chopra

  We are currently running an AWS container that utilizes FFmpeg for live streaming while concurrently saving the stream as an MP4 file. However, we encountered an issue during a recent live stream session that was functioning correctly until approximately 13 minutes in, at which point FFmpeg reported the following error logs :

  


  ffmpeg [flv @ 0x555c4bdfe680] Failed to update header with correct duration.
2023-09-07T23:06:38.490+05:30 [flv @ 0x555c4bdfe680] Failed to update header with correct filesize.

  It's worth noting that we have conducted hundreds of live streams on YouTube without encountering this error before ; this is the first occurrence of such an issue.

  


  We would greatly appreciate it if you could investigate and provide insights into the underlying problem causing these error messages.

  The .CR2 file can be opened normally in Photoshop and Windows Photo Viewer (with the raw image extension).

  


  I can get around this issue by converting the image to JPEG using another program, but I would to work with the original file if possible.
