• Error running exec() for FFMPEG in Android app

  28 juillet 2015, par Douglas Anunciação

  When following this tutorial : https://github.com/cine-io/android-ffmpeg-with-rtmp and after compiling successfully in Ubuntu 14.04 64-bits I get an IOException when trying to execute ffmpeg :

  String abspath = getApplicationInfo().nativeLibraryDir;
  
  
  
          // Change the permissions
  
          try {
  
              Runtime.getRuntime().exec("chmod -R 777 "+ abspath).waitFor();
  
          } catch (InterruptedException e) {
  
              e.printStackTrace();
  
          } catch (IOException e) {
  
              e.printStackTrace();
  
          }
  
  
  
          String cameraPath = "/storage/emulated/0/DCIM/Camera/";
  
          String cmd = "ffmpeg -i "+ cameraPath + "VID_20150728_150045662.mp4 -y "+ cameraPath + "output.mp4";
  
  
  
          ProcessBuilder processBuilder = new ProcessBuilder(cmd);
  
  
  
          final Map environment = processBuilder.environment();
  
  
  
          environment.put("LD_LIBRARY_PATH", getDir("lib", 0).getAbsolutePath());
  
  
  
          try {
  
              Process process = processBuilder.start();
  
          } catch (IOException e) {
  
              e.printStackTrace();
  
          }

  And the IOException is :

  Error running exec(). Command : [ffmpeg -i
  /storage/emulated/0/DCIM/Camera/VID_20150728_150045662.mp4 -y

  Does anyone knows the solution for this problem ?

• How to install PHP FFMPEG on windows 10 64 Bit

  7 septembre 2017, par PlanetHackers

  I want to install the PHP FFMPEG on my system. My system configuration is :

  OS : Windows 10 64 Bit
  XAMPP v3.2.2
  PHP v7.0.15

  I found many tutorial but nothing found working. May be due to 64 bit system. I wanted to add a watermark to a video through PHP. That’s why I need the ffmpeg extension. I also tried through Composer but did not get success.

  lavc/vaapi_encode : Don't return error if the underlying driver doesn't support B frames
  The underlying driver need not support B frames - since they are enabled
  
  by default for some codecs, it is better to disable them rather than
  
  returning an error in this case.  This makes the default settings usable
  
  for low-power encoding on Intel platforms.
