  • 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.
