• Image sequence to video stream ?

  22 août 2015, par Hauns TM

  Like many people already seem to have (there are several threads on this subject here) I am looking for ways to create video from a sequence of images.

  I want to implement my functionality in C# !

  Here is what I wan’t to do :

  /*Pseudo code*/
  
  void CreateVideo(List<image> imageSequence, long durationOfEachImageMs, string outputVideoFileName, string outputFormat)
  
  {
  
      // Info: imageSequence.Count will be > 30 000 images
  
      // Info: durationOfEachImageMs will be &lt; 300 ms
  
  
  
      if (outputFormat = "mpeg")
  
      {
  
      }
  
      else if (outputFormat = "avi")
  
      {      
  
      }
  
      else
  
      {
  
      }
  
  
  
      //Save video file do disk
  
  }
  
  </image>

  I know there’s a project called Splicer (http://splicer.codeplex.com/) but I can’t find suitable documentation or clear examples that I can follow (these are the examples that I found).

  The closest I want to do, which I find here on CodePlex is this :
  How can I create a video from a directory of images in C# ?

  I have also read a few threads about ffmpeg (for example this : C# and FFmpeg preferably without shell commands ? and this : convert image sequence using ffmpeg) but I find no one to help me with my problem and I don’t think ffmpeg-command-line-style is the best solution for me (because of the amount of images).

  I believe that I can use the Splicer-project in some way (?).

  In my case, it is about about > 30 000 images where each image should be displayed for about 200 ms (in the videostream that I want to create).

  (What the video is about ? Plants growing ...)

  Can anyone help me complete my function ?

• Xuggle build failed on ubuntu x64 ?

  3 avril 2012, par beginner

  After downloading the source code from GIT hub I setup the enviroment variables
  as Xuggle YouTube Video said so

     export XUGGLE_HOME=/usr/local
  
     export PATH=$XUGGLE_HOME/bin:$PATH
  
     export LD_LIBRARY_PATH=$XUGGLE_HOME

  Then I simply started the ant test by command

  ant run-tests

  Which gave me following output with error in the end ..

• How to concatenate flv file into one ? [closed]

  25 juin 2013, par it_is_a_literature

  There is a file named input.txt

  file '/home/1.flv'
  
  file '/home/2.flv'

  I can use the command to Concatenate 1.flv and 2.flv into a mp4 file.

  # there are two files in output.mp4
  
  ffmpeg -f concat -i input.txt -c copy output.mp4

  When i use the following command

  ffmpeg -i "concat:1.flv|2.flv" -c copy output.mp4

  I found the there is only one file 1.flv in the output.mp4, why ?
