• libavcodec/libfdk-aacenc.c error while compiling ffmpeg

  27 août 2019, par Knot83

  I’m trying to install FFMPEG on my Raspeberry following this procedure : https://gist.github.com/adddog/d82581faf10d666d35b9771eaa65d5ac.

  While doing this step of the procedure :

  sudo apt-get install -y xserver-xorg-dev libxext-dev build-essential libxi-dev libglu1-mesa-dev libglew-dev
  
  wget http://www.ijg.org/files/jpegsrc.v9c.tar.gz
  
  tar xvfz jpegsrc*
  
  cd jpeg-9c
  
  ./configure --enable-shared --prefix=$CONFIGURE_PREFIX
  
  make -j4
  
  sudo make install

  I’m getting this error while compiling :

  libavcodec/libfdk-aacenc.c:289:34: error: ‘AACENC_InfoStruct {aka struct <anonymous>}’ has no member named ‘encoderDelay’; did you mean ‘nDelay’?
  
  </anonymous>

  Can you please help me ? Whithout solving this issue I cannot install FFMPEG at all.

  Thanks,
  Claudio

• How can I start a live stream fixing stdout of ffmpeg prob ?

  8 janvier 2019, par Antonin Rouard

  It is my first time here. Be kind with me ^^ trying to do my best.
  I want to stream a 24/7 live opn Toutube with live-stream-radio ; everything goes well when I start until FFMPEG find an error at code 1 with stdout, probably a problem with the codec or the version of FFMPEG (bad compilation ?).

  How can I fix this to start a stream ? :) thx

  Tried to do a stream with OBS, but it is too complicated on my Raspbian (Raspberry Pi 3B+). I compiled many versions of FFMPEG and I don’t know how to fix this.

  live-stream-radio —start (file directory)

  /////

  ffmpeg stdout :

  ffmpeg err :

  Error : ffmpeg exited with code 1 : Error initializing complex filters.
  Invalid argument

• FFmpeg : convert any video to square 1:1 video with blurred side bars

  16 novembre 2019, par L0Lock

  Very similar to this topic :

  FFmpeg : How to convert vertical video with black sides, to video 16:9, with blurred background sides

  I’m trying to make myself a bat file that will automate my Instagram video creations.
  The idea is that I make videos of variable resolutions and variable aspect ratios. I don’t want to spend time on each video just to make it fit.

  So here’s my goal with that bat file :

  • Must output a square video
  • The original video must keep its original aspect ratio no matter what it is
  • The blank spaces filling the voids from the original video and the square aspect ratio must be filled with a squared & blurred version of the original video
  • Optionally, let me choose the output resolution (for encoding time saving and because AFAIK Instagram displays only 600px² videos(?))

  So far I managed to get results that work only for either vertical or horizontal videos but not both. Or end up with the original video cropped, which I don’t want : I frame my subjects as I want and I don’t want to frame them forethinking the additional cropping a FFmpeg encoding could do.

  This is my script so far :

  echo off
  
  :again
  
  
  
  ffmpeg.exe -i "%~1" ^
  
      -c:v libx264 -crf 23 -filter_complex "[0:v]scale=600*2:600*2,boxblur=luma_radius=min(h\,w)/20:luma_power=1:chroma_radius=min(cw\,ch)/20:chroma_power=1[bg];[0:v]scale=600:-1[ov];[bg][ov]overlay=(W-w)/2:(H-h)/2,crop=w=600:h=600"  -profile:v baseline -level 3.0 -pix_fmt yuv420p -preset faster -tune fastdecode ^
  
      -c:a aac -ac 2 -b:a 128k ^
  
      -movflags faststart ^
  
      "%~p1%~n1_Instagramized.mp4" -y
  
  
  
  if NOT ["%errorlevel%"]==["0"] pause
  
  shift
  
  if "%~1" == "" goto:eof
  
  goto:again

  EDIT :

  Thanks to @Gyan I got the solution. I added my input as well :

  Since I might reuse that bat file often and might want to change the output resolution, It’s not handy to have the resolution hardcoded in six different places.
  So I create a variable called SquareSize which is called using %SquareSize% (instead of the hardcoded resolution) and set at the begining of the file using set SquareSize=XXX. So now I can change easily when I need just by opening it and editing the XXX.

  echo off
  
  :again
  
  
  
  set SquareSize=600
  
  
  
  ffmpeg.exe -i "%~1" ^
  
      -c:v libx264 -crf 23 ^
  
      -filter_complex "[0:v]split=2[blur][vid];[blur]scale=%SquareSize%:%SquareSize%:force_original_aspect_ratio=increase,crop=%SquareSize%:%SquareSize%,boxblur=luma_radius=min(h\,w)/20:luma_power=1:chroma_radius=min(cw\,ch)/20:chroma_power=1[bg];[vid]scale=%SquareSize%:%SquareSize%:force_original_aspect_ratio=decrease[ov];[bg][ov]overlay=(W-w)/2:(H-h)/2" ^
