• Create a slide show from images in a folder [on hold]

  26 juillet 2017, par randommman

  So i have a folder with images like so :

  1.png
  
  2.png
  
  3.png
  
  .. etc

  I am trying to generate a slideshow video from the videos, i have the following code :

          string ffmpegPath = "ffmpeg.exe";
  
          string ffmpegParams = "-y - r " + mimtime + " -i " + Images + "- c:v libx264 -r 15 - pix_fmt yuv420p -vf fps = 90 " + Video;
  
  
  
          Process ffmpeg = new Process();
  
          ffmpeg.StartInfo.FileName = "cmd.exe";
  
          ffmpeg.StartInfo.Arguments = "/k " + ffmpegPath + " " + ffmpegParams;
  
          ffmpeg.Start();

  But this is giving me permision denied, because I think I need to add the individual images. How can I get the individuall images to generate a video ?

• Merge videos with different start times and show them on a grid

  1er août 2017, par shamaleyte

  I have multiple video files of a conference call. However, each participant joined the call at a different time, which resulted in the fact that each video file has a different start time offset values.

  Video   Start Time
  
  ------------------
  
  Video1  00:00
  
  Video2  00:10
  
  Video3  01:40

  My purpose is to play back this conference. However, I did not record the conference as 1 video, it is recorded with multiple video files, instead.
  How do I stitch these videos ?

  There is also a paid solution to merge video fragments to a single clip – this will make the client-side much simpler. But can I do it for free ?

  The expected outcome is to have one video showing three videos on a grid.
  When ffmpeg stitches the videos, it should consider their start time values properly so that the videos are played accordingly.

• ffmpeg - Creates a Terminal like Text Video Instead of Slide Show Of Images

  15 novembre 2017, par RAJESH KUMAR ARUMUGAM

  I am using ffmpeg encoder to render Images in my Android App with the Help of this Library

  The following Command is used to Render video from a list of images.

  String command[] = {"-r","1/5","-i",gpxfile.getAbsolutePath(),"-c:v","libx264","-vf","fps=25","-pix_fmt","yuv420p",root.getAbsolutePath()+"/"+"video.mp4"};

  and here the gpxfile is my text file that contains the following

      file '/storage/emulated/0/DCIM/Camera/P_20170807_143916.jpg'
  
      duration 2
  
      file '/storage/emulated/0/DCIM/Pic/P_20170305_142948.jpg'
  
      duration 5
  
      file '/storage/emulated/0/DCIM/Camera/P_20170305_142939.jpg'
  
      duration 6
  
      file '/storage/emulated/0/DCIM/Pic/P_20170305_142818.jpg'
  
      duration 2

  My Problem is While Running the Command it renders a Terminal Like Black Screen with the TextPaths inside the file instead of a Video...!!!
  Any Suggestions...??

  Here is my Project Source Code
