• How to keep the file size of a stream small and have manycam show a live picture ?

  6 juillet 2017, par P. Dee

  I am using this command

  ffmpeg -i "rtsp://184.72.239.149/vod/mp4:BigBuckBunny_175k.mov" "C:\wamp\www\streaming.mjpeg"

  to stream to "C :\wamp\www\streaming.mjpeg". Then I am using SimpleHTTPServer to create a web server for this folder.

  Then I am pointing ManyCam’s ip camera to the address of the file on the web server

  http://127.0.0.1:8000/streaming.mjpeg

  And select it in ManyCam.

  As a result ffmpeg creates a file that gets bigger and bigger and ManyCam shows an endless time-lapsed loop of what the camera records or recorded minutes ago.

  How to keep the file size small and have ManyCam show a live video feed ?

• 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.
