• lavc : remove libschroedinger encoding and decoding wrappers

  lavc : remove libschroedinger encoding and decoding wrappers
  The library has stopped being developed and Debian has removed it
  
  from its repositories citing security issues.
  
  The native Dirac decoder supports everything the library has and basic
  
  encoding support is still provided via the native vc2 (Dirac Pro, intra
  
  only version of Dirac) encoder. Hence, there's no reason to still support
  
  linking to the library and potentially leading users into security issues.

• php exec() works on some calls, not other similar ones

  15 mai 2013, par Kyle

  I have a php script that cuts up video. Here are three exec() commands - two execute properly while one does not :

  Works :

  sudo ffmpeg -i /home/vidserver/videos/$filename.mp4 -ss $ctime -t 00:00:06 -acodec copy -vcodec copy -y /var/vidcache/test$x.mp4

  Works :

  sudo ffmpeg -i /var/vidcache/test$x.mp4 -qscale:v 1
  /var/vidcache/i$x.mpg

  Does not work :

  sudo ffmpeg -i
  concat :"i0.mpg|i1.mpg"
  -qscale:v 1 /var/vidcache/output.mpg

  /var/vidcache has 777 privs and www-data is in the sudoers file with NOPASSWD (yes, I know - this is just for debug purposes before I lock down security).

  When I run the last command from a php script from the command line by itself, it DOES work. (Running as www-data or root.) But when I try to put it in a function called from a web page, it does NOT work.

  Any ideas ?

• How to run FFMPEG at my web host server

  26 avril 2013, par user1978421

  I want to perform some video process at my web host server. I don't think the web host server will allow me to execute an exe file for security reasons.

  Should I use SharpFFMpeg ?

  I have downloaded SharpFFMpeg. But it's lacking a proper documentation.

  Can someone give one example how to perform a conversion from one video format to another ?

  I have written my execution program, but the compiler says it cannot file the file specified. What's wrong with it ?

          string command = @"D:\Recorded TV\ffmpeg.exe -i ""Australia's Toughest Police_QUEST_2013_04_17_21_57_00.wtv"" -s 800x400 throughCS.mp4";
  
          try
  
          {
  
              ProcessStartInfo psi = new ProcessStartInfo("\"" + command + "\"");
  
              psi.RedirectStandardOutput = true;
  
              psi.UseShellExecute = false;
  
              psi.CreateNoWindow = true;
  
              Process proc = new Process();
  
              proc.StartInfo = psi;
  
              proc.Start();
  
              string result = proc.StandardOutput.ReadToEnd();
  
              tb1.Text = result;
  
              Debug.WriteLine(result);
  
          }
