The Bit Goblin video transcoder.
|
||||
|
||||
## Installing from RPM
|
||||
|
||||
Installing from the Bit Goblin repository is easy! Add the following repo file to `/etc/yum.repos.d/bitgoblin.repo`:
|
||||
|
||||
```
|
||||
[bitgoblin]
|
||||
name=Bit Goblin repository
|
||||
baseurl=http://repo.metaunix.net/dnf
|
||||
enabled=1
|
||||
gpgcheck=0
|
||||
```
|
||||
|
||||
Update your package sources just to make sure all was added properly:
|
||||
|
||||
```
|
||||
dnf updateinfo
|
||||
```
|
||||
|
||||
Then install dragoon! Use the command below if you DON'T want DNF to install a bunch of unnecessary stuff to meet OpenJDK's weak dependencies; otherwise a regular `dnf install dragoon` is fine:
|
||||
|
||||
```
|
||||
dnf --setopt=install_weak_deps=False --best install dragoon
|
||||
```
|
||||
|
||||
## Building
|
||||
|
||||
Currently this project is targeting Java 17 LTS and uses Maven to manage the software lifecycle. Thus, you must have a Java 17 JDK and Maven installed to build this project.
