This is a quick guide to installing the following in CentOS 7:
CentOS 7 requires a tweak to the process I'd used for CentOS 6. The links below are generally suitable for EL7.
If you don't have the EPEL repo installed already:
sudo yum -y install epel-release
Import a repo from Nux (this is third party, obviously):
sudo rpm --import http://li.nux.ro/download/nux/RPM-GPG-KEY-nux.ro sudo rpm -Uvh http://li.nux.ro/download/nux/dextop/el7/x86_64/nux-dextop-release-0-5.el7.nux.noarch.rpm
Install ffmpeg from this repo:
sudo yum -y install ffmpeg ffmpeg-devel
Confirm it's working:
ffmpeg reporting back
This is easiest to grab via RubyGems.
Install Ruby and RubyGems
yum install -y ruby rubygems
And then it's a simple gem install:
gem install flvtool2
And we're done.
flvtool2 - done.
This one is quite easy on CentOS 7:
yum install -y gpac mediainfo
This package is much more common, so the install is also more straightforward.
Install any prerequisites:
yum install -y gcc php-devel php-pear
Install the package itself:
yum install -y ImageMagick ImageMagick-devel
Install it into PHP:
pecl install imagick echo "extension=imagick.so" > /etc/php.d/imagick.ini
Last, but not least:
service httpd restart
