  • Why is "ffmpeg : command not found" in heroku, even with proper buildpack/config ?

    14 novembre 2022, par Jim

    In a node.js app hosted on heroku, ffmpeg is used by spawning processes, but is throwing errors anytime an ffmpeg command runs

    


    the error ffmpeg: command not found is thrown both in cli test heroku run ffmpeg as well as production logs

    


    Ive considered :

    


      

    • buildpack order

      • 


    • buildpack clearing/re-adding/redeploying

      • 


    • buildpack required env vars

      • 


    • heroku-stack-20 conflicts with buildpack#1 somehow ?

      • 


    


    Buildpack order :

    


      

    1. https://github.com/jonathanong/heroku-buildpack-ffmpeg-latest.git

      2. 


    2. https://github.com/heroku/heroku-buildpack-awscli.git

      3. 


    3. https://github.com/timanovsky/subdir-heroku-buildpack.git

      4. 


    4. heroku/nodejs

      5. 


    


    Buildpack configs - from watching build logs, even though i havent set ffmpeg path, a default is found.

    


    beginning build logs (completes successfully, runs successfully - minus ffmpeg) :

  • OCI runtime exec failed : exec failed : (...) executable file not found in $PATH" : unknown

    12 octobre 2024, par Uğur Kaya

    I have dockerized an app which has ffmpeg installed in it via libav-tools. The app launches without problem, yet the problem occured when fluent-ffmpeg npm module tried to execute ffmpeg command, which was not found. When I wanted to check the version of the ffmpeg and the linux distro set up in the image, I used sudo docker exec -it c44f29d30753 "lsb_release -a" command, but it gave the following error : OCI runtime exec failed: exec failed: container_linux.go:296: starting container process caused "exec: \"lsb_release -a\": executable file not found in $PATH": unknown

    



    Then I realized that it gives me the same error with all the commands that I try to run inside the image or the container.

    



    OCI runtime exec failed: exec failed: container_linux.go:296: starting container process caused "exec: \"ffmpeg -a\": executable file not found in $PATH": unknown


    



    This is my Dockerfile :

    



    FROM ubuntu:xenial
FROM node
RUN apt-get -y update
RUN apt-get --yes install libav-tools
RUN mkdir -p /usr/src/app
WORKDIR /usr/src/app
COPY package.json /usr/src/app
RUN npm install
COPY . /usr/src/app
RUN npm run build
ENV NODE_ENV production
EXPOSE 8000
CMD ["npm", "run", "start:prod"]


    



    I would kindly ask for your help. Thank you very much !

    


  • How to fix ffmpeg complex filters "Invalid stream specifier" [duplicate]

    15 mai 2019, par Chase

    This question already has an answer here :

    I’m attempting to scale and blur (sections of) a video with ffmpeg complex filters. This has actually been working in production for years.

    I’m now running a newer build of ffmpeg on Ubuntu 18.04 and getting an error relating to the filters where the same command works fine on Ubuntu 16.04’s ffmpeg against the same video.


    Specifically, I’m seeing the following error :

    mov,mp4,m4a,3gp,3g2,mj2 @ 0x56055a5902c0] Invalid stream specifier: vs0.
    
    Last message repeated 1 times
    
Stream specifier 'vs0' in filtergraph description ... matches no streams.

    Has something about the complex filter API changed that would make this same input invalid in a newer version of ffmpeg ?

    The command in question is just running the following in a Bash terminal.

    ffmpeg -ss 60 -i ~/test.mp4 -y -filter_complex "[0:v]scale=-2:'min(320,ih)'[vs0];[vs0]crop=in_w/9:in_h/2:0:0,boxblur=5:1:cr=3:ar=3[b0];[vs0]crop=in_w/9:in_h/2:in_w-out_w:0,boxblur=5:1:cr=3:ar=3[b1];[vs0]crop=(in_w-2*in_w/9):in_h/20:in_w/9:0,boxblur=5:1:cr=3:ar=3[b2];[vs0][b0]overlay=0:0[ovr0];[ovr0][b1]overlay=main_w-overlay_w:0[ovr1];[ovr1][b2]overlay=main_w/9:0[vs1]" -map [vs1] -an -ac 2 -b:a 128k -acodec aac -b:v 1024k -r 30 -vcodec libx264 -t 300 -y -preset slow -movflags faststart -pix_fmt yuv420p -f mp4 ~/out.mp4

    If we break up the complex filter statement, it looks like :

    [0:v]scale=-2:'min(320,ih)'[vs0];
    
[vs0]crop=in_w/9:in_h/2:0:0,boxblur=5:1:cr=3:ar=3[b0];
    
[vs0]crop=in_w/9:in_h/2:in_w-out_w:0,boxblur=5:1:cr=3:ar=3[b1];
    
[vs0]crop=(in_w-2*in_w/9):in_h/20:in_w/9:0,boxblur=5:1:cr=3:ar=3[b2];
    
[vs0][b0]overlay=0:0[ovr0];[ovr0][b1]overlay=main_w-overlay_w:0[ovr1];
    
[ovr1][b2]overlay=main_w/9:0[vs1]

    On ffmpeg version N-86980-g62b7553 (Ubuntu 16.04), everything works great as it has done for years.

    $ ffmpeg -ss 60 -i ~/test.mp4 -y -filter_complex "[0:v]scale=-2:'min(320,ih)'[vs0];[vs0]crop=in_w/9:in_h/2:0:0,boxblur=5:1:cr=3:ar=3[b0];[vs0]crop=in_w/9:in_h/2:in_w-out_w:0,boxblur=5:1:cr=3:ar=3[b1];[vs0]crop=(in_w-2*in_w/9):in_h/20:in_w/9:0,boxblur=5:1:cr=3:ar=3[b2];[vs0][b0]overlay=0:0[ovr0];[ovr0][b1]overlay=main_w-overlay_w:0[ovr1];[ovr1][b2]overlay=main_w/9:0[vs1]" -map [vs1] -an -ac 2 -b:a 128k -acodec aac -b:v 1024k -r 30 -vcodec libx264 -t 300 -y -preset slow -movflags faststart -pix_fmt yuv420p -f mp4 ~/out.mp4
