• How can I remove encode information from mediainfo for H265 HEVC .mkv ? Remove Writing library ?

  14 octobre 2020, par For Fun

  I want to know how I can remove encode settings from the mediainfo with mkvpropedit or ffmpeg ?

How can I remove metadata from a flv file ?
I found this command :
ffmpeg -i INPUT -c copy -bsf:v 'filter_units=remove_types=6' OUTPUT
  
for only h264 AVC !

  


  so how can you do this for h265 HEVC ?
What command do i need to use ?

  


  I want to know how I can do this for just to copy -c copy the file ?

• FFMPEG scale, zoom, and concat filter

  2 août 2018, par Karate_Dog

  I am using ffmpeg for android to produce video with mp4 format. I’m having trouble getting this command to work in FFMPEG, basically I am trying to add two images, scale them, add zoom effect, and finally concat the result into one video file. I have done something like this :

  ffmpeg 
  
  -t 8 -i image1.png
  
  -t 8 -i image2.png
  
  -filter_complex
  
  [0:v]scale=720:720[scl1]; [1:v]scale=720:720[scl2];
  
  [scl1]zoompan=z=if(lte(zoom, 1.0), 1.55, max(1.001, zoom - 0.0010)):d=205, fade=t=out:st=7:d=1[v0];
  
  [scl2]zoompan=z=if(lte(zoom, 1.0), 1.55, max(1.001, zoom - 0.0010)):d=205, fade=t=in:st=0:d=1,fade=t=out:st=7:d=1[v1];
  
  [v0][v1]concat=n=2:v=1:a=0, format=yuv420p[v] -map [v] outputVideo.mp4

  Been tinkering with this command for a while but still can’t get it to work and I got error :

  Input link in1:v0 parameters (size 1280x720, SAR 0:1) do not match the corresponding output link in0:v0 parameters (1280x720, SAR 45:31)
  
  [Parsed_concat_7 @ 0xf0d77600] Failed to configure output pad on Parsed_concat_7

• Ghost image issues with ffmpeg -filter_complex displace

  5 juillet 2022, par raul.vila

  I've (almost) been able to apply a displacement based on 2 animated gaussian noise videos, but I'm having issues with a ghost image. A picture is worth a thousand words.

  


  Here you have a script to replicate the issue :

  


  ffmpeg -y -t 2 -f lavfi -i color=c=blue:s=160x120 -c:v libx264 -tune stillimage -pix_fmt rgb24 00_empty.mp4
ffmpeg -y -i 00_empty.mp4 -vf "drawtext=text=string1:y=h/2:x=w-t*w/2:fontcolor=white:fontsize=60" 01_text.mp4
ffmpeg -y -t 2 -f lavfi -i color=c=gray:s=160x120 -c:v libx264 -tune stillimage -pix_fmt rgb24 02_gray.mp4
ffmpeg -y -i 01_text.mp4 -i 02_gray.mp4 -i 02_gray.mp4 -filter_complex "[0][1][2]displace=edge=mirror" 03_displaced_text.mp4


  


  It creates a test video with a scrolling text and a gray dummy video. Then it applies a displacement based on the gray video. If I understand correctly, because the gray video is 100% gray, it should leave the video unchanged (or maybe displace everything by a fixed ammount of pixels), but it creates a "shadow". I tried with 3 different pixel formats (yuv420p, yuv444p, rgb24) because I found this question on stackoverflow talking about that :

  


  

  • Why are Cb and Cr planes displaced differently from lum by the displace complex filter in ffmpeg ?

  


  


  ffmpeg version 5.0.1-full_build-www.gyan.dev

  


  Any idea will be welcome.
  
Thanks !
