• scale a video to multiple qualities and add watermark

  8 mars 2019, par jared zek

  hello I have a ffmpeg command that scales a video to 2 different qualities and adds a watermark, the problem here is that the watermark is scaled along with the videos and it looks horrible

  D:\electron\brenda\node_modules\ffmpeg-static\bin\win32\x64\ffmpeg.exe -i C:\Users\Andy\Desktop\entrada\videoplayback.mp4 -i C:\Users\Andy\Desktop\entrada\marca.png -filter_complex [0:0]scale=854:480[wm]; [wm][1:0]overlay=x=0:y=0[out] -map [out] -map 0:a -movflags faststart -preset fast -y C:\Users\Andy\Desktop\salida/480_videoplayback.mp4 -filter_complex [0:0]scale=640:360[wm]; [wm][1:0]overlay=x=0:y=0[out] -map [out] -map 0:a -movflags faststart -preset fast -y C:\Users\Andy\Desktop\salida/360_videoplayback.mp4

  video scaled to 360 with watermark

  I want the watermark to remain in its original size and not escalate with the video, thank you for your help I’ve been here for hours

  Looking for a solution to my ffmpeg video overlay code :

  import subprocess as sp
  
  
  
  cmd='ffmpeg', '-i', 'C:/Users/Michael.hovan/Desktop/test/front.mov', '-i', 'C:/Users/Michael.hovan/Desktop/test/persp.mov', '-i', 'C:/Users/Michael.hovan/Desktop/test/side.mov', '-i', 'C:/Users/Michael.hovan/Desktop/test/top.mov', '-filter_complex' \
  
   '[1:v]scale=iw/4:-1:flags=lanczos[pip1];' \
  
   '[2:v]scale=iw/4:-1:flags=lanczos[pip2];' \
  
   '[3:v]scale=iw/4:-1:flags=lanczos[pip3];' \
  
   '[0:v][pip1]overlay=main_w-overlay_w-10:main_h-overlay_h-10[bg1];' \
  
   '[bg1][pip2]overlay=(main_w-overlay_w)/2:main_h-overlay_h-10[bg2];' \

  '-map', '[v]', '-map', '[a]', '-ac', '1', 'C:/Users/Michael.hovan/Desktop/test/output.avi'
  
  
  
  sp.call(cmd)

  I’m honestly stumped as to why the code is giving me a "returned non zero exit status".

• License or not ? As website owner do i have to pay license for using ffmpeg (x264) -> mp4 decoding in my webiste ?

  28 août 2014, par linderman

  I am very confused about my legal or illegal rights to use H.264 mp4 file.

  I had long time reading various websites about should i pay license or not ... still cant understand ..

  So here is the exact situation :

  I have website , where users can upload their videos. Videos are taken with their smart-phones or home cameras , or webcam etc.

  After they upload their videos , i am using FFMPEG (x264) to convert the video from 3gp, mov, or even "mp4 to mp4".

  Then other users can watch these decoded videos on my website.

  I am not charging the end users anything. My website is free for uploaders and viewers.

  You will be right if you say that my website have the same purpose as youtube - and you will be right.. video sharing !

  So ME - as website owner , hosting buyer and ffmpeg user ... should i have to pay license ? OR ABANDON THE MP4 decoding in my website ?

  Thank you
