• ffmpeg drawtext same font size and position on all kind of videos

  25 janvier 2018, par Bilal Akmal

  I’m drawing text and an icon on input video which user uploads. I’m able to draw the test and icon both successfully using two separate ffmpeg filter -vf and -filter_complex. But the problem is the output is not consistent for different size and resolution of videos. I mean I need to place the text and icon in top left corner with some padding, but it’s totally different positioned and sized on each video.
  So can you help me how I can calculate the font based on video height and width to make it consistent, I mean the text box should be of same size irrespective of video dimensions.

  Here’s the commands I’m using :

  ffmpeg -i input.mp4 -vf "drawtext=fontfile=OpenSans-Regular.ttf:text=\’LIVE\’:fontcolor=white:fontsize=40:x=50:y=50:box=1:boxcolor=red@0.9:boxborderw=20,format=yuv420p, drawtext=fontfile=OpenSans-Regular.ttf:text=’\ %eif :$1+t:d’:fontcolor=white:fontsize=40:x=195:y=50:box=1:boxcolor=black@0.4:boxborderw=20,format=yuv420p" -c:v libx264 -c:a copy -movflags +faststart output1.mp4 -y

  ffmpeg -i input.mp4 -vf "drawtext=fontfile=OpenSans-Regular.ttf:text=\’LIVE\’:fontcolor=white:fontsize=40:x=50:y=50:box=1:boxcolor=red@0.9:boxborderw=20,format=yuv420p, drawtext=fontfile=OpenSans-Regular.ttf:text=’\ %eif :$1+t:d’:fontcolor=white:fontsize=40:x=195:y=50:box=1:boxcolor=black@0.4:boxborderw=20,format=yuv420p" -c:v libx264 -c:a copy -movflags +faststart output1.mp4 -y
  ffmpeg -i output1.mp4 -i eye.png -filter_complex "[1]lut=a=val*1[a] ;[0][a]overlay=190:48" -pix_fmt yuv420p -c:a copy output2.mp4 -y ;

• ffmpeg smooth scroll in smooth loop [closed]

  22 décembre 2024, par Igor Scherbickij

  I need help creating code for ffmpeg. I have a picture with dimensions x000*1080 (the length will be more than 1920, but it depends on the picture). I want to scroll it endlessly and seamlessly (the picture repeats)

  


  i write this code, who work but have freezes
  
ffmpeg -loop 1 -i sr_innernet.png -vf "scroll=horizontal=0.0004,crop=1920:1080:0:0,format=yuv420p" -r 120 -t 10 output.mp4

  


  After this i googled other method, who can make it smoothly. but this method no works with looping(image scrolled once)

  


  ffmpeg -r 1 -loop 1 -t 61 -i sr_innernet.png -filter_complex "color=white:s=1920x1080, fps=fps=60[bg];[bg][0]overlay=x='-t*120':shortest=1[video]" -preset ultrafast -map [video] output.mp4


  


  I tried to combine these two methods. I also asked the AI, but all the answers did not suit me. Using if else in the code causes the image to jump when it reaches a certain limit. some combinations scrolled the image seamlessly, but the height of the displayed part was several times less than 1080.

  


  i need have videostream who
  
- scroll image in loop
  
- have smooth(use white background with frequency 60 fps)

  


  AI recommended freaky recommendation with if else statements, or other variants with overlay, but all them dont suit me. thats or have end of picture(i see white screen after scroll picture) or just jumping image
