Inputing a List of Files for Concatenation with Node.js Module fluent-ffmpeg
26 juin 2018, par carpiediemVersion information
- fluent-ffmpeg version : 2.1.2
- ffmpeg version : 3.4.2
- OS : Windows 10
Code to reproduce
ffmpeg('C:/path/to/list.txt').mergeToFile('C:/path/to/out.mp4', 'C:/path/to/temp');
list.txt :
file 'C:/path/to/chunk01.ts'
file 'C:/path/to/chunk02.ts'
file 'C:/path/to/chunk03.ts'
file 'C:/path/to/chunk04.ts'Note : I’ve tried both absolute and relative paths, with the same result.
Expected results
A video file at
C:/path/to/out.mp4
that matches the 4 files in list.txt, concatenated end-to-end.Observed results
An empty file at
C:/path/to/out.mp4
with 0 duration and only 15kB in size. No errors were thrown.This is the command that I’m trying to duplicate (it works as expected, with relative paths in list.txt) :
C:/path/to> ffmpeg -f concat -i list.txt -c copy out.ts
stdout & stderr
stdout was empty. stderr is copied below (with file names modified to match the ones above) :
