• Add array of filenames to ffmpeg video with fluent-ffmpeg

  9 septembre 2020, par lowcrawler

  My nodejs program has an array of (full path) filenames for a few hundred jpegs. These files are not all in the same directory (but they all sort correctly). These are all located on various network shares that the host has access to.

  


  I'd like to turn these into timelapse videos, but I'm not entirely sure how to do this. Note, some videos will be 400+ images.

  


  I have thought of brute-force copy the the files across the network into sequential filenames on the local system, then run ffmpeg using an image pattern ... but I will need to do this hundreds of times per hour, 24/7 and I'd rather not needlessly make file copies (nor do I wish to delve into deep use of the local file system by nodejs).

  


  I have tried doing multiple .addInput('path/to/file') - chaining a hundred of them together and I seem to only get a single frame video.

  


  The question Add multiple images to video fluent-ffmpeg appears close, but is too opaque for me to know if it's on the right track.

  


  The question fluent-ffmpeg from an array of input files gives me hope but I keep getting errors. (I will keep digging on this path unless someone has other input)

  


  given FFMPEG can work with a readable stream, I also wondered if there would simply be a way to create a readable stream from the array of image files ?

  


• Use a video editing library (not executable) via Node [on hold]

  25 septembre 2018, par Merc

  I need to edit clips using node. I am looking around, and most (if not all) libraries seem (like Fluent FFMpeg) seem to be based on the fact that they run FFMPEG as an executable and get the resulting output.

  That’s not what I want. I worked with FFMPEG executable in the past, and I know how flaky it is in terms of return codes and error codes.

  Ideally, I would love to find a native library for video editing and make calls using node.

  In terms of libraries :

  • Gstreamer
  • FFmpeg/LibAV (does they come with C libraries to bind to ?)
  • libVLC

  In terms of binding with them :

  • node-gir. Gstreamer seems to have updated git files

  • native bindings. For example Gstreamer has gstreamer-superficial. I couldn’t find any javascript bindings forFFMPEG — only "run the executable and hope for the best" libraries

  • VLC has a bindings library that is quite old and had its last commit years ago.

  Am I getting this all wrong ?
  My ideal outcome is to have a nice, robust library that I use directly using node, but my lack of experience in terms of using native libraries, and the somehow fragmented world of video editing libraries.

• Set path while installing [duplicate]

  12 janvier 2021, par Education 4Fun

  My requirement is to set a path(C :/ffmpeg) while installing the software itself for my application(which I made)
  
A reference that it's possible(While installing python 3.8.0 we have check box by ticking it we can add the path of python automatically)
  
This is the main requirement which I wanna do with my application

  


  

  


  About My application :
  
My application is a simple video editing application that runs on cmd as it uses FFmpeg its path should be set only then the application will work
The application is coded in python and the GUI is made using pyqt5 The application runs on cmd like the commands and all here is a reference image for observation enter image description here

  


  

  


  So it's mandatory to add the path else FFmpeg will not recognize. If there is any way to do in building setup like how python can add the path as per user requirement refer to the image (1st image)

  


  About Files in C :/ffmpeg
Files in FFmpeg folder refer to image for that info

  


  

  


  Hope the query is a bit clear.
Thanks a lot
