• Checkinstall equivalent on Red Hat (Santiago)

  29 octobre 2013, par Dalius

  I'm not familiar with Red Hat, never used it before.

  I'm installing ffmpeg from source, following this guide https://trac.ffmpeg.org/wiki/CentosCompilationGuide

  On Debian, after using make to compile ffmpeg, I would use checkinstall to install ffmpeg for all users. How can I do the same on Red Hat ?

• Installing ffmpeg on Heroku with Go (Golang) app

  17 novembre 2015, par Kevin Cantwell

  I have a Go app that uses ffmpeg bindings that I’d like to deploy on Heroku. I am able to install ffmpeg successfully using ddollar’s multi buildpack in conjunction with shunjikonishi’s ffmpeg buildpack and kr’s go buildpack. However, no matter what I try, the app fails on the call to pkg-config with the following output :

  $ git push heroku master

  The command that fails is pkg-config --cflags libavcodec libavformat libavutil libswscale. However, when I run that command in a bash console it outputs -I/app/vendor/ffmpeg/include, which is what I’d expect.

  I believe that when the Go buildpack builds, it loses track of the ffmpeg package configuration information somehow. These are my config vars for the app :

  $ heroku config -s
  
  CGO_CFLAGS=-I/app/vendor/ffmpeg/include
  
  PKG_CONFIG_PATH=vendor/ffmpeg/lib/pkgconfig

  My question is : How do I get past this error ? Clearly the answer is related to the PKG_CONFIG_PATH variable, but I’m super confused on this one.
