• FFMPEG Video Encode Single Input Multi Output

  1er août 2014, par ShyamKG

  I have a custom video encoder filter which can produce upto 5 different bitrates for the same resolution.

  Note that single instance of the encoder is optimized for producing these multiple outputs. Every encode call returns 5 output buffers.
  This means that I would not want to run more than one encoder instance.

  I need to integrate this encoder to FFMPEG which should give multiple outputs for a single input. I have referred the following link regarding creating multiple outputs.
  https://trac.ffmpeg.org/wiki/Creating%20multiple%20outputs

  In this link multiple outputs are created by running multiple encoder instances which is not my requirement.

  Is there any way by which we can configure ffmpeg to give multiple output for one encoder instance ?

• lavfi : split frame_count between input and output.

  lavfi : split frame_count between input and output.
  AVFilterLink.frame_count is supposed to count the number of frames
  
  that were passed on the link, but with min_samples, that number is
  
  not always the same for the source and destination filters.
  
  With the addition of a FIFO on the link, the difference will become
  
  more significant.
  Split the variable in two : frame_count_in counts the number of
  
  frames that entered the link, frame_count_out counts the number
  
  of frames that were sent to the destination filter.

• Input and output path in Android

  16 juillet 2014, par user3675966

  I am using FFMPEG to make a video editor. I stuck when selecting a folder :

  1/ I will show "File Manager" to user. They can choose a folder then return a path. How can choose a folder and get its path. For example : /sdcard/videokit/.

  

  Here is my code, I must choose a mp4 file (not a folder I want).

  public void openFolder()
  
  {
  
      Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
  
      Uri uri = Uri.parse(Environment.getExternalStorageDirectory().getPath()
  
          + "/sdcard/");
  
      intent.setDataAndType(uri, "folder|video/mp4");
  
      startActivityForResult(Intent.createChooser(intent, "Select Folder"),PICK_VIDEO_OUTPUT_REQUEST);
  
  }

  Thank you in advance !
