• FFmpeg error Output file #0 does not contain any stream

  27 juin 2018, par Sushin Pv

  I’m getting an error while cutting a portion of a video using FFmpeg

  Following is my code

  String[] cmd = {"ffmpeg -ss 0 -i "+mPath+" -t 30 -c copy "+ (Environment.getExternalStorageDirectory().getAbsolutePath()+"/sample.mp4")};
  
  executeCommand(cmd);

  Function executeCommand

  void executeCommand(String[] cmd) {
  
      try {
  
          fFmpeg.execute(cmd, new FFmpegExecuteResponseHandler() {
  
              @Override
  
              public void onSuccess(String message) {
  
                  Toast.makeText(VideoFullScreen.this, "finished :" + message, Toast.LENGTH_SHORT).show();
  
              }
  
  
  
              @Override
  
              public void onProgress(String message) {
  
  
  
              }
  
  
  
              @Override
  
              public void onFailure(String message) {
  
                  Log.e("Error",message);
  
              }
  
  
  
              @Override
  
              public void onStart() {
  
  
  
              }
  
  
  
              @Override
  
              public void onFinish() {
  
  
  
              }
  
          });
  
      } catch (FFmpegCommandAlreadyRunningException e) {
  
          e.printStackTrace();
  
      }
  
  }

• Unable to execute CLI commands through PHP

  13 janvier 2012, par user940154

  OS : ubuntu 11.10
  Webserver : Apache
  Code : PHP
  I am trying to display the output of command "ffmpeg -i " on the webpage using php.
  Required : The webpage should show the information about video (text).
  Whats happening : The webpage shows no text output on running the php code.
  If I was however doing system("ls") the code runs fine and outputs the list of files.
  Here's my code

  <?php
  
   echo "Details of video file:";
  
   system('ffmpeg -i /home/atish/Videos/T2V0040006_Angled_ride_720x576i_FLDCMB.avi');
  
  ?>

  The same command works fine on my shell, and my system has ffmpeg installed. Here's a snapshot of executing this command directly on shell :

  I have tried appending "DISPLAY=:0" to my command and also done "xhost +" before running php code, but nothing is helping me out.

  Thanks.

• Why error happened when build ffmpeg by ndk-build ?

  26 mars 2014, par Martin

  I have try build the ffmpeg for Android in Windows 7 , but it error when ndk-build.

  And the error log is like the following :

  Wun@Wun-PC ~/ffmpeg/jni/ffmpeg
  
  $ ndk-build
  
  SharedLibrary  : libffmpeg.so
  
  C:/cygwin/home/Wun/ffmpeg/obj/local/armeabi/libavcodec.a(log2_tab.o):(.rodata+0x0): multiple definition of `ff_log2_tab'

  C:/cygwin/home/Wun/ffmpeg/obj/local/armeabi/libavutil.a(log2_tab.o):(.rodata+0x0): multiple definition of `ff_log2_tab'
  
  C:/cygwin/home/Wun/ffmpeg/obj/local/armeabi/libavformat.a(log2_tab.o):(.rodata+0x0): first defined here

  make: *** [/home/Wun/ffmpeg/obj/local/armeabi/libffmpeg.so] Error 1

  I have already remove the
  OBJS-$(CONFIG_SHARED)                  += log2_tab.o
  in the Makefile of libavformat and libavcodec.

  But the problem still happened...

  Should I delete the libavcodec.a , libavformat.a , libavutil.a and libswscale.a , and rebuild again ??

  Does somebody know how to solve this problem ?

  Thanks in advance.
