• Compress video with ffmpeg4android library

  30 mars 2015, par Huy Tower

  I tried to follow ffmpeg4android library, and I get the problem when compressing the video, as the Log image below.

  I use intent to transfer to Compressing Media class,

  Intent intent = new Intent(this, CompressingMedia.class);
  
  intent.putExtra("file_path", mLlItems.get(0).getPath());
  
  startActivity(intent);

  This is the class was transfered to :

  public class CompressingMedia extends BaseWizard {
  
  
  
  @Override
  
  public void onCreate(Bundle savedInstanceState) {
  
      super.onCreate(savedInstanceState);
  
  
  
      Intent intent = getIntent();
  
  
  
      Log.d(Prefs.TAG, "path " + intent.getExtras().getString("file_path"));
  
      // /storage/emulated/0/DCIM/Camera/VID_20140312_090612.mp4
  
  
  
      String command = "ffmpeg -y -i " + intent.getExtras().getString("file_path") + 
  
              " -strict experimental -s 320x240 -r 15 -aspect 3:4 -ab 12288 -vcodec mpeg4 -b 2097152 -sample_fmt s16 /sdcard/out.mp4";
  
  
  
      // if you want to change the default work location (/sdcard/videokit/) use the uncomment the below method.
  
      // It must be defined before calling the copyLicenseAndDemoFilesFromAssetsToSDIfNeeded method,
  
      // in order for this method to copy the assets to the correct location.
  
              //      setWorkingFolder("/sdcard/videokit/");
  
  
  
      // this will copy the license file and the demo video file.
  
      // to the videokit work folder location.
  
      // without the license file the library will not work.
  
      copyLicenseAndDemoFilesFromAssetsToSDIfNeeded();
  
  
  
      commandStr = command;
  
      setCommand(commandStr);
  
  
  
      runTranscoing();
  
      }
  
  }

  Although I received the notification Transcoding Successfully, but it looks like the capacity of file after compressing is always be 0. (the log in the bottom of images)

  I don’t know the result as image below is good or not, I can not get the expected result - The video was compressed totally successfully.

  Someone know why after compressing the file is always be 0, please tell me. Thanks.

• FFMPEG options for video streaming

  26 février 2014, par YorgZ

  I am trying to use ffmpeg to stream video using ffserver. You will find below the ffserver1.conf file, and the log output from the ffmpeg command.

  One of the errors references presets, and everytime I try to use presets I get the error "File not found, even after copying all the preset files in the current directory.

  Thanks for the help.

• FFMPEG x264 MP4 Encoding all grey

  7 mars 2013, par Brianjs

  I am currently using FFMPEG v1.1 on CentOS 6.3.

  I configured FFMPEG with :

  ./configure --arch=x86_64  --enable-libmp3lame  --enable-librtmp  --enable-libtheora --enable-libvorbis  --enable-libx264 --enable-pthreads --enable-gpl --enable-runtime-cpudetect 

  when I run a simple command to record live input to MP4 by :

  ffmpeg -f video4linux2 -s 640x480 -i /dev/video0 /home/irdb/Desktop/test.mp4

  I get nothing, just a grey screen with some artifacts around the edges. However when I run the same command as .MPG it comes out fine. I need it in MP4 format however.

  On a side note I am running x264-0.120 installed through yum

  My question is, is there a problem with the way I compiled ffmpeg ? Or is it possibly something else ?

  edit :

  Output from example as requested :

  # ffmpeg -f video4linux2 -s 640x480 -t 5 -i /dev/video0 -strict 2 /home/irdb/Desktop/test.mp4
