  • "-bash : ffmpeg@2.8 : command not found" Mac OS X 10.11 El Capitan

    3 janvier 2021, par Billy McRae

    So I am using that operating system, and because of that, had to try workarounds for months just to get ffmpeg at all. I happened to find someone who said to download an older version so I bumped my head against the desk and yelled "Why didn't I think of that before ?!" So after a very long process, ffmpeg@2.8 finally installed via Homebrew after I left it overnight, literally for that long.

    


    With one issue, leaving me the same as before...

    


    MacBook-Pro-2:core_stable duckman$ ffmpeg@2.8
-bash: ffmpeg@2.8: command not found


    


    I tried just "ffmpeg" as well...

    


    MacBook-Pro-2:core_stable duckman$ ffmpeg --version
-bash: ffmpeg: command not found


    


    I also tried exporting it to "path", whatever that means, as the install gave me an error that said it was "keg-only".

    


    MacBook-Pro-2:core_stable duckman$ echo 'export PATH="/usr/local/opt/ffmpeg@2.8/bin:$PATH"' >> /Users/duckman/.bash_profile
MacBook-Pro-2:core_stable duckman$ export LDFLAGS="-L/usr/local/opt/ffmpeg@2.8/lib"
MacBook-Pro-2:core_stable duckman$   export CPPFLAGS="-I/usr/local/opt/ffmpeg@2.8/include"
MacBook-Pro-2:core_stable duckman$ export PKG_CONFIG_PATH="/usr/local/opt/ffmpeg@2.8/lib/pkgconfig"


    


    It still wouldn't work.

    


    which ffmpeg gave me nothing :

    


    MacBook-Pro-2:core_stable duckman$ which ffmpeg
MacBook-Pro-2:core_stable duckman$


    


    which ffmpeg@2.8 also gave me nothing :

    


    MacBook-Pro-2:core_stable duckman$ which ffmpeg@2.8
MacBook-Pro-2:core_stable duckman$


    


    I also tried another user's suggestion to move ffmpeg to /usr/local/bin/, which also didn't work :

    


    MacBook-Pro-2:core_stable duckman$ echo 'export PATH="/usr/local/opt/ffmpeg@2.8/bin:$PATH"' >> /usr/local/bin/
-bash: /usr/local/bin/: Is a directory


    


    locate ffmpeg@2.8 gave me this :

    


    MacBook-Pro-2:core_stable duckman$ locate ffmpeg@2.8

    PLEASE help because I've been trying so many wacky ways to install ffmpeg for months and nothing has worked for me. This is the closest I have gotten, with all the dependencies (apparently) installed, and it still doesn't work. For everyone else on the planet pretty much as I gather, they can install ffmpeg with a simple command on the terminal, and for me it has been the opposite way, and it is very frustrating and it is embarrassing that I have to have this older computer as my main.

If you think configure made a mistake, make sure you are using the latest

ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "ffbuild/config.log" produced by configure as this will help
solve the problem.


    


    I have been trying to solve this error, and have installed gcc with brew, if i run gcc -v I can see my installed gcc version :

    So if gcc is installed correctly (i think) why is it failing with a gcc error when I build ffmpeg ?

  • Color Tracking Drone Code Test

    7 octobre 2017, par AR Drone

    I am trying to follow a GitHub to allow my AR Drone to fly autonomously for some time ; however, I am having a lot of troubles setting up.

    As a follow up to my prior question, I was able to solve

    import cv2
    
import libardrone.libardrone

    I reinstalled opencv and I realized the documentation was incorrect ; it was supposed to be

    import libardrone.ardrone

    Solving these two problems let me to be able to attempt the track.py given here : https://github.com/JJLewis/ColorTracking-ARDrone2.0-Python.

    Running track.py gives me the follow errors even though I have ffmpeg installed correctly.

    Entering FFMPEG into my Mac terminal yields the following : which leads me to believe that FFMPEG is installed correctly ; however it is not detected or something.

    Doing brew info opencv shows a check for FFMPEG for openCV so I am not really sure how I am getting an error for this part of the code.
    As a beginner, I am having difficulties resolving these issues. My specifications are as follows Mac 10.12, Python 2.7.14, and OpenCV 3.3.0_3.
