• Crop video scale square to round shape -Android

  13 septembre 2019, par Adil

  Currently I’m developing video editing app, in which i want to overlay video to image i used FFMPEG library and use overlay command and export video to video.mp4 format

  Here is done with overlay command :

  private void extractImagesVideo() {
  
      File moviesDir = Environment.getExternalStoragePublicDirectory(
  
      Environment.DIRECTORY_PICTURES
  
  );
  
  
  
  String filePrefix = "extract_picture";
  
  String fileExtn = ".mp4";
  
  
  
  File dir = new File(moviesDir, "VideoEditor");
  
  int fileNo = 0;
  
  while (dir.exists()) {
  
  fileNo++;
  
  dir = new File(moviesDir, "VideoEditor" + fileNo);
  
  
  
  }
  
  dir.mkdir();
  
  File dest = new File(dir, filePrefix + "%03d" + fileExtn);
  
  
  
  Log.d(TAG, "startTrim: dest: " + dest.getAbsolutePath());
  
  
  
  // String complexCommand[]={"-y","-i",mStrImagePath,"-i",mStrVideoPath,"-filter_complex","[0]scale=720:1280:force_original_aspect_ratio=decrease,drawbox=x=10:y=10:w=100:h=100:color=pink@0.5:t=max: (ow-iw)/2:(oh-ih)/2,setsar=1[backd],[backd][1] overlay=x=(main_w-overlay_w)/(main_w-overlay_w):y=(main_h-overlay_h)","-acodec","copy",dest.getAbsolutePath()};
  
  
  
  String complexCommand[]={"-y","-i",mStrVideoPath,"-f","lavfi","-i","color=c=black:s=1920x1080","-filter_complex","[0:v]scale=w=0.80*iw:h=0.80*ih[scaled],[1:v][scaled]overlay=x=0.10*main_w:y=0.10*main_h:eof_action=endall[out]","-acodec","copy",dest.getAbsolutePath()};
  
  
  
  
  
  // String complexCommand[]={"-y","-i",mStrImagePath,"-i",mStrVideoPath,"-filter_complex","[1:v] scale=200:200 [ovr1], [1:v] scale=200:200 [ovrl2], [0:v][ovr1] overlay=25:25:enable='between(t,0,20)' [temp1], [temp1][ovrl2] overlay=50:50:enable='between(t,20,40)'","-acodec","copy",dest.getAbsolutePath()};

  /* Remove -r 1 if you want to extract all video frames as images from the specified time duration.*/
  
  execFFmpegBinary(complexCommand);
  
  }

  Issue is video showing square shape i want to crop video into rounded shape, i check almost solutions and check also FFMPEG commands , i found mask overlay on video but isn’t a proper solution

• Ffmpeg : Scale+crop video then overlay image ?

  8 juillet 2019, par skitzo

  This is my first SO question. Help me help you help me : does this question need any clarification ?

  Goal : A script that makes Instagram-ready videos with audio, and a logo overlay. The script takes in an audio and video source and combines them. Important : the logo should have a consistent position and size for each video. This probably means that all output videos should have the same width x height.

  Any alternate approaches are welcome !

  The ffmpeg command I’m calling from python is below. I try to scale the video to 720 :-2 (so auto-height), then crop a 500x500 square from the center. The choices of 720 and 500 are arbitrary ; better approaches are welcome.

  ffmpeg -i video.mp4 -i logo.png -i audio.mp3 -filter_complex "[0:v]scale=720:-2,crop=500:500[bg];[bg][1:v] overlay=(W-w)/2:(H-h)/2" -pix_fmt yuv420p -map 0:v -map 2:a -shortest + output.mp4

  This script errors on some videos.

  [Parsed_crop_1 @ 0x7fcf96401f00] Invalid too big or non positive size for width '500' or height '500'
  
  [Parsed_crop_1 @ 0x7fcf96401f00] Failed to configure input pad on Parsed_crop_1

  I’m new to ffmpeg so please guide me to correct usage of filter_complex. Thank you !

• What parameter should use to create adaptive hls videos in different scale using ffmpeg and shaka packager for VOD streaming ?

  25 juin 2019, par Rahul

  I am trying to package HLS with shaka packager in a different scale from 144x256 to 1080x1920 for adaptive streaming using hevc, It is working fine, but Is there some more parameter required to put for good video quality and optimization.

  Below are the command I used :

  ffmpeg -i original.mp4 -c:a aac -strict experimental -b:a 128k -c:v libx265 -vf scale=144:256 144_256_h265.mp4 -hide_banner
  
  
  
  ffmpeg -i original.mp4 -c:a aac -strict experimental -b:a 128k -c:v libx265 -vf scale=360:640 360_640_h265.mp4 -hide_banner
  
  
  
  ffmpeg -i original.mp4 -c:a aac -strict experimental -b:a 128k -c:v libx265 -vf scale=720:1280 720_1280_h265.mp4 -hide_banner
  
  
  
  ffmpeg -i original.mp4 -c:a aac -strict experimental -b:a 128k -c:v libx265 -vf scale=1080:1920 1080_1920_h265.mp4 -hide_banner
