A centos7 rpm/yum source is recommended.
The epel + rpmfusion source has been used in centos 6, but so far (), rpmfusion has not released the source under centos7/rhel7, so it is a pain to install the software.
For the lack of yum software, I used to be manually searching on the http://rpm.pbone.net/, and then looking for the most approximate transformation version of the download. For example, in centos, The centos or redhat el package of the same version is preferred. If not, find the latest fedora version for download. If not, use the centos/rhel package of the previous version or fedora package.
That is, yesterday or early this morning, in the http://rpm.pbone.net/manual solution rely on the installation of smplayer/mplayer process, found this source, because there are several packages are downloaded under this domain name, therefore, a direct access is actually a yum source, and the maintainer is very active. Thank you!
Currently, there are rhel/centos6 and rpm/yum sources in li. nux. ro. It depends on the epel source, so you must configure the epel source first. However, under normal circumstances, we will install the epel source, which is a quality source recommended by centos.
Instructions for use, very concise, not too long, http://li.nux.ro/repos.html
In addition, the source atrpms is also worth recommending and does not compare the repeatability or conflict between the two sources. If you want to ensure stability, we recommend that you install the required software and uninstall the third source to avoid replacing the system package. (this may be the case. It is said that atrpms will replace the system package, after all, the versions of rhel/epel are often too old)
