  • ERROR while Installing FFMPEG through Dockerfile

    27 juin 2018, par drexdelta

    I am trying to install ffmpeg in dockerfile.
    For that, I am using following this link . Please, have look at the link before answering.
    Following the answer given to that link, I am using these commands,,,

    RUN apt-get install -y software-properties-common

    RUN add-apt-repository -y ppa:mc3man/trusty-media

    RUN apt-get update

    RUN apt-get install -y ffmpeg RUN apt-get install -y frei0r-plugins

    After successfully executing first two commands, apt-get update fails miserably.

    Hit ://deb.debian.org jessie Release.gpg

    Err ://ppa.launchpad.net jessie/main amd64 Packages Get:3
     ://security.debian.org jessie/updates/main amd64 Packages [589 kB]

    Hit ://deb.debian.org jessie Release

    W : Failed to fetch

    404 Not Found

    E : Some index files failed to download. They have been ignored, or old
    ones used instead.

    And I understood the reason that why it fails .

    I would have certainly followed the solution given in the above link. Since I am working on docker. I can’t do much. is there any other way to install FFMPEG on docker with all it’s tools and functionalities ?

    Moreover, I wasn’t able to post the acutal content of the error, due to constrain that " I can’t post more than 8 links , since my ratings are low." .
    so in the error log, there is ’http’ , before ’://’.

  • How to build dense trajectory without sudoers permission

    8 février 2019, par Albe

    I’m stuck for a week trying to install iDT(https://github.com/chuckcho/iDT) in a server hosted by university in which I don’t have root permissions. (VERSION=12.04.5 LTS)

    I tried to install the 2 main libraries (opencv and ffmpeg) following part(different versions) of this tutorial : http://dridini.blogspot.com/

    I managed (I think) to install the libraries in local :

    ffmpeg -version

    I exported the LD_LIBRARY_PATH where all .so are.(I cannot perform ldconfig after)
    But when I try to make this is the result :
