• Trying to combine 2 FFmpeg commands

  21 août 2019, par user11588722

  I have 2 FFmpeg commands which I need t combine, for the sake of speed.

  This one builds a simple slideshow using a list of images located on my remote server.

  ffmpeg -y -f concat -safe 0 -protocol_whitelist "file,http,https,tcp,tls" -i "Temp/images.txt" -filter_complex "[0]scale=7680x4320,zoompan=z='if(lte(zoom,1.0),1.2,max(1.001,zoom-0.0006))':x='iw/2-(iw/zoom/2)':y='ih/2-(ih/zoom/2)':fps=30:d=300" -c:v libx264 -preset veryfast -shortest "Temp/video.mp4"

  This one overlays the video we just created aswel as another video (marquee.mp4) and a showwaves effect ontop of a background image, then adds audio. (showwaves effect is tied to said audio)

  ffmpeg -y -framerate 30 -i "Assets/Screens/background.png" -i "Temp/audio.mp3" -filter_complex "movie=Temp/video.mp4[a];movie=Temp/marquee.mp4:loop=0,setpts=N/FRAME_RATE/TB[b];[0][a]overlay=570:70[c];[c][b]overlay=570:880[d];[1:a]showwaves=mode=cline:s=254x81:scale=sqrt:colors=0x222222,colorkey=0x000000:0.01:0.1,format=yuva420p[w];[d][w]overlay=148:375,scale=1920:1080[outv]" -map "[outv]" -map 1:a -movflags +faststart -c:v libx264 -c:a aac -preset veryfast -shortest done.mp4

  Would it be possible to combine all of this into one command ? So that rather than taking the created slideshow video and overlaying, it just generates the slideshow in-place.

  Thank you for your time.

• How can I merge these 2 FFmpeg commands ?

  7 juin 2019, par WebDev

  I have two commands which are part of a larger set of commands. Basically I need to merge these two into one command to speed things up.

  ffmpeg -y -f concat -safe 0 -protocol_whitelist "file,http,https,tcp,tls" -i "photos.txt" -i "mainscreen.png" -i "audio.mp3" -filter_complex "scale=3840x2160,zoompan=z='if(lte(zoom,1.0),1.2,max(1.001,zoom-0.0015))':x='iw/2-(iw/zoom/2)':y='ih/2-(ih/zoom/2)':s=1280x720:fps=15:d=120, overlay=(main_w-overlay_w)/2:(main_h-overlay_h)/2, drawtext=fontfile=font.otf:text='%%~ni':fontcolor=black:fontsize=32:x=90:y=582" -preset veryfast -tune stillimage -shortest -pix_fmt yuv420p "slideshow.mp4"
  
  
  
  ffmpeg -y -i "slideshow.mp4" -filter_complex "[0:a]showwaves=mode=cline:s=110x36:r=15:scale=sqrt:colors=0x222222,colorkey=0x000000:0.01:0.1,format=yuva420p[v];[0:v][v]overlay=77:444,scale=1280:720[outv]" -map "[outv]" -map 0:a -preset veryfast "done.mp4"

  Firstly creates a slideshow and adds text, then draws a showwaves effect onto the video.

  Update

  From Gyan’s response, and after tinkering for a while, it kind of works how I needed it to. It does what I wanted, but keeps throwing "depreciated pixel format" error. Here’s the updated command once I finished. What is the problem, and is the command written properly ?

  ffmpeg -y -f concat -safe 0 -protocol_whitelist "file,http,https,tcp,tls" -i "images.txt" -i "screen.png" -i "audio.mp3" -filter_complex "scale=3840x2160,zoompan=z='if(lte(zoom,1.0),1.2,max(1.001,zoom-0.0015))':x='iw/2-(iw/zoom/2)':y='ih/2-(ih/zoom/2)':s=1280x720:fps=15:d=120, overlay=(main_w-overlay_w)/2:(main_h-overlay_h)/2, drawtext=fontfile=Assets/Fonts/font.otf:text='%%~ni':fontcolor=black:fontsize=32:x=90:y=582[v];[2:a]showwaves=mode=cline:s=110x36:r=15:scale=sqrt:colors=0x222222,colorkey=0x000000:0.01:0.1,format=yuva420p[w];[v][w]overlay=77:444,scale=1280:720[outv]" -map "[outv]" -map 2:a -c:v libx264 -c:a aac -preset veryfast -shortest -pix_fmt yuv420p "done.mp4"

  Second update

  Thanks to Gyan for helping me better understand the command. Here is the final code which does what I need :

  ffmpeg -y -f concat -safe 0 -protocol_whitelist "file,http,https,tcp,tls" -i "images.txt" -i "screen.png" -i "tmp.audio.mp3" -filter_complex "[0]scale=3840x2160,zoompan=z='if(lte(zoom,1.0),1.2,max(1.001,zoom-0.0015))':x='iw/2-(iw/zoom/2)':y='ih/2-(ih/zoom/2)':s=1280x720:fps=15:d=120, overlay=(main_w-overlay_w)/2:(main_h-overlay_h)/2, drawtext=fontfile=font.otf:text='%%~ni':fontcolor=black:fontsize=32:x=90:y=582[v];[2:a]showwaves=mode=cline:s=110x36:r=15:scale=sqrt:colors=0x222222,colorkey=0x000000:0.01:0.1,format=yuva420p[w];[v][w]overlay=77:444,scale=1280:720[outv]" -map "[outv]" -map 2:a -preset veryfast -shortest -pix_fmt yuv420p "done.mp4"

  Only change from Gyan’s code is I removed [p] ;[1][p] and replaced with a comma to achieve what I needed. Seems to work perfect now, ignoring the depreciated pixels warning.

• Missing ffmpeg https protocol : How to add https protocol in ffmpeg installed in Elastic beanstalk ?

  24 novembre 2023, par threeFatCat

  I installed ffmpeg latest static build in my Elastic Beanstalk instance following this answer.

  


  When I run my code in the server I got this message :

  


  https protocol not found, recompile FFmpeg with openssl, gnutls or securetransport enabled.


  


  I checked the buildinfo in https://johnvansickle.com/ffmpeg and https protocol is listed as supported, but when I run :

  


  ffmpeg -protocols


  


  https is missing.

  


  How do I proceed ?
