• Gitlab CI - Combine two docker images into a single stage

  12 mars 2024, par seal.r00t

  I have this gitlab-ci.yaml file. Using this file I execute my k6.io load test from pipeline. Now I need to execute some FFmpeg commands during the run stage, and my question is how do I make the FFmpeg tool available to the run stage. Do I need to grab the image that has FFmpeg and add it next to grafa/k6 or something else ?

  I tried adding two name tags under the run stage for using two images but it didn't work and returned a syntax error.

• Feeding a series of images to ffmpeg as each image is created [closed]

  5 février 2013, par Mark Schneider

  I'm trying to use ffmpeg to build a 1280x720 slide-show from a sequence of pictures and videos, but I have concerns about potential disk I/O bottleneck.

  I expect a typical slide-show to have about 50 pictures and 2-3 videos (10-15 seconds each at 30 fps). I would like to show each picture for 3-4 seconds (possibly with a
  Ken Burns effect) with a smooth 2 second crossfade between each set of pictures (or for pictures adjacent to videos - between the picture and the first/last frame of the video).

  Given about 50 pictures, the crossfades alone would amount to about 3,000 images (50 transitions x 2 secs/transition x 30 fps). And I suppose if I implement a Ken Burns effect during each picture's 3-4 second showing, I'd have to provide ffmpeg with individual images for each of those frames. (I'm writing a script in Ruby that will pull a list of images from a database and in turn call ImageMagick to create the individual images for each frame. As I understand it, the RMagick library interfaces with ImageMagick such that the output images come back as in-memory objects without needing to write to disk. FWIW, I'm developing in Windows 8 and will deploy to Heroku.)

  All of the slideshow examples I've found online feed ffmpeg a set of images which have already been created. However, in an effort to avoid waiting on considerable disk I/O, I'd like to feed each image to ffmpeg as the image is created rather than create them all in advance.

  Is there a way to send each image file to ffmpeg on the fly as the file is created in memory ?

• FFMPEG "Could find no file with path" and "No such file or directory"

  4 mai 2020, par bmw_58

  I try to convert a sequence of pictures to video file. 
But I get from ffmpeg the response, that no such file or directory

  



  Does someone have a solution for it ?

  



  My command line :

  



  ffmpeg -r 1/5 -start_number 0 -i "C:\Users\USER\Desktop\Pictures\%3d.png" -c:v libx264 -r 30 -pix_fmt yuv420p C:\Users\USER\Desktop\Pictures\out.mp4


  



  The error :

  



          C:\Users\USER>ffmpeg -r 1/5 -start_number 0 -i "C:\Users\USER\Desktop\Pictures\%3d.png" -c:v libx264 -r 30 -pix_fmt yuv420p C:\Users\USER\Desktop\Pictures\out.mp4
