• FFMpeg Unknown function in zoompan filter

  4 août 2022, par Luciano Salemme

  i'm using ffmpeg with zoompan filter in my local environment whit the following command and it works well :

  


  ffmpeg -y -i "https://my.domain/workspaces/1/a_render_dir/video_spotx.mp4" -i "https://my.domain/workspaces/1/Gallery/travel_6.jpeg" -i "https://my.domain/workspaces/1/Gallery/travel_6.jpeg" -i "https://my.domain/workspaces/1/Gallery/travel_6.jpeg" -i "/usr/app/src/output/video.mp4/text_0.png" -i "/usr/app/src/output/video.mp4/text_1.png"    -filter_complex "[0]drawbox=x=0:y=0:w=iw:h=ih:color=00FF00@1:t=fill[padded];[0]format=yuva420p,pad=iw*2:ih*2:color=black@0,zoompan=z='if(lt(it,0),2,if(lte(pzoom,1.0),2,max(1.56,pzoom-0.005789473684210526)))':x=0:y=0:d=1:s=950x540[zp],[padded][zp]overlay=x='if(lt(t,3.04),t*213/3.04,213)':y='if(lt(t,3.04),t*50/3.04,50)':eval=frame[zp_stream],[1:v]scale=237.5:-1 [image1],[2:v]scale=237.5:-1 [image2],[3:v]scale=237.5:-1 [image3],[4:v]scale=475:-1 [image4],[5:v]scale=237.5:-1 [image5],[zp_stream][image1] overlay=95:54:enable='between(t,3,8)' [overlay1],[overlay1][image2] overlay=380:216:enable='between(t,3,8)' [overlay2],[overlay2][image3] overlay=532:54:enable='between(t,5,10)' [overlay3],[overlay3][image4] overlay=475:270:enable='between(t,1,8)' [overlay4],[overlay4][image5] overlay=0:0:enable='between(t,1,8)' [overlay5]" -map "[overlay5]" -pix_fmt yuv420p -map 0:a -c:a copy "/usr/app/src/output/video.mp4/render_video.mp4"


  


  However when i build a docker container and run that command it is not working. The output error is the following :

  


  [Parsed_zoompan_3 @ 0x2a08ac0c5140] [Eval @ 0x3ec4ec4c9ad0] Unknown function in 'it,0),2,if(lte(pzoom,1.0),2,max(1.56,pzoom-0.005789473684210526)))'


  


  I tried to add a fixed z value to the zoompan filter, and the command works also inside the container, so the issue is on the zoompan syntax.

  


  Here is my docker file

  


  FROM node:16

ENV NODE_ENV=production

RUN apt-get -y update && \
    apt-get install -y  ffmpeg \
    build-essential libcairo2-dev libpango1.0-dev libjpeg-dev libgif-dev librsvg2-dev 

WORKDIR /usr/src/app
COPY . .
RUN npm ci --production --silent

CMD node src/index.js


  


  Problem starts when i switch on new Macbook pro with M1 processor, but i'm not sure it's related, i build the image with the following command :

  


  docker buildx build --platform linux/x86_64  -t render-job .


  


  On my macchine there is ffmpeg 5.0.1 installed, but on docker container the command apt-get install -y     ffmpeg installs just the follow wersion :

  


  ffmpeg version 4.1.9-0+deb10u1 Copyright (c) 2000-2022 the FFmpeg developers
  built with gcc 8 (Debian 8.3.0-6)


  


  I don't think is relate to the version, because before to build with M1 processor the zoompan filter was working also in the container.

  


  Any help is appreciated.
Thanks.
