• How to reduce conversion/compression time in FFmpeg and How to merge command ?

  18 mai 2017, par Patel Pinkal

  I want to reduce time taken to create new video after adding text in original video using FFmpeg
  I had tried to search and I found this code given below for reducing time.

   -y -i /sdcard/videokit/in.mp4 -strict experimental -vcodec libx264 -preset ultrafast -crf 24 -acodec aac -ar 44100 -ac 2 -b 36000k -s 1280x720 -aspect 16:9 -metadata:s:v:0 rotate=0 /sdcard/videokit/out3.mp4

  Now, I want to add text in video and it is done in FFmpeg, by this command and its 100% working.

    String[] addTextCommand = {
  
              "-i",
  
              "" + realFilePath,
  
              "-vf",
  
              "drawtext=fontsize=50:fontfile=/storage/emulated/0/Download/Cerbetica-regular.ttf:fontcolor=red:text='"
  
                      + strText +
  
                      "':x=0:y=0: box=1: boxcolor=black@0.5:boxborderw=10: x=0: y=(h-text_h)/2",
  
              "-strict",
  
              "-2",
  
              outputFilePath};

  Now my problem is how do I merge this two code and make one single command to make an edited video and also take less time to create a new video. In this, I have tried this command but it’s not working.

     String[] addTextCommand = {
  
              "-i",
  
              "" + realVideoPath,
  
              "-vf",
  
              "-c:v", "libx264",
  
              "-preset", "ultrafast",
  
              "-crf", "24",
  
              "-acodec", "aac",
  
              "-ar", "44100",
  
              "-ac", "2",
  
              "-b", "36000k",
  
              "-s", "1280x720",
  
              "-aspect", "16:9",
  
              "-metadata:s:v:0 rotate=0",
  
              "drawtext=fontsize=50:fontfile=/storage/emulated/0/Download/Cerbetica-regular.ttf:fontcolor=red:text='"
  
                      + strText +
  
                      "':x=0:y=0: box=1: boxcolor=black@0.5:boxborderw=10: x=0: y=(h-text_h)/2",
  
              "-strict",
  
              "-2",
  
              outputFilePath};

  If anyone has an idea how to make command of FFmpeg please describe it and explain how to use it.

  Using command of @Mulvya I got this in the console.

  Here is the of the generated files.

  This is my Android.mk file.

  LOCAL_PATH := $(call my-dir)
  
  include $(CLEAR_VARS)
  
  LOCAL_C_INCLUDES := $(ANDROID_NDK)/sources/ffmpeg-3.3
  
  LOCAL_CFLAGS := -Os -fpic -marm -march=armv7-a -mfloat-abi=softfp -mfpu=neon
  
  LOCAL_MODULE := MyFFmpeg
  
  LOCAL_SRC_FILES := arm/videoKit.c arm/ffmpeg.c arm/ffmpeg_filter.c arm/ffmpeg_opt.c arm/cmdutils.c
  
  LOCAL_STATIC_LIBRARIES := libavdevice libavformat libavfilter libavcodec libavutil libswresample libswscale

• FFMPEG image to video showing blank video

  18 avril 2017, par Ravi Rupareliya

  Here is my command to create a video from multiple images.

  File f = new File(Environment.getExternalStorageDirectory() + "/abc.mp4");
  
  
  
  try {
  
      f.createNewFile();
  
      ffmpeg.execute(new String[]{"-y","-r","1/5","-i","" + "/" + "image%01d.jpg","-pix_fmt","yuv420p","-c:v","libx264","-crf","23","-s","640x480",f.getPath()}, listener);
  
  } catch (Exception e) {
  
      e.printStackTrace();
  
  }

  I have multiple images available at with having names like image1.jpg, image2.jpg etc etc.

  It is creating video file with some 100-200 KB but it showing blank images in VLC player.

  When i try to run it with Windows Media Player, it only runs if it is in repeat mode from player, otherwise it is not playing.

  Output in onSuccess()
