• FFMpeg with PHP-7.0 on Ubuntu

  25 octobre 2018, par Gabriel Bueno Lemes da Silva

  I have a NGINX server with PHP-7.0 and I would like to install the ffmpeg-php extension. I’ve been trying for a few days now and in many ways.

  The method that worked so far was compiling ffmpeg (https://ffmpeg.org/releases/ffmpeg-4.0.2.tar.bz2) manually, but when trying to compile ffmpeg-php (https: // sourceforge. net / projects / ffmpeg-php / files / ffmpeg-php / 0.6.0 / ffmpeg-php-0.6.0.tbz2 / download) I am encountering the following error message :

  Can someone give me a light ? I do not know what else to do !

• Compile OpenCV3 with Cuda7.5 ffmpeg (latest) issue OpenSUSE 13.2

  23 janvier 2016, par Ingeborg

  I am using an OpenSUSE 13.2-X86-64 and a Geforce 940M GPU. I want to work with it on the Qt5 IDE.
  For this purpose, i have installed my GPU Driver with the Cuda7.5 toolkit rpm from the cudazone. Everything is nearly fine.
  It detects everything I have made and executed a couple of the cuda samples.

  As next step, i have installed the current FFmpeg version with nvenc and other libraries like Xvid and many of
  the other usefull stuff which would be to much to list it here. After that i have downloaded the current
  OpenCV-3.0.0 source code and ran cmake-gui where i have added cuda, ffmpeg, Qt5 etc and maked it.

  On different points of the make session (make -j4) i get this kind of mistake from my console (The list of the Multiple definition
  error is much longer). This is the first one.

• Can anyone help 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. can anyone help me please ?

  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.

  thank you in advance

  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. heres the updated command once i finished. can you spot 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 (once again) 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.

  FINAL UPDATE :
  Gyan’s updated code works perfect, a massive thank you to you sir. you also helped me understand your work which was very helpful.
