Servercheck question
 

Hello I must to install :
these :
FFmpeg (recommended but optional)
WGET (recommended but optional)
but I don't know how to check is this installed already on my server and how to do this ?
Please help me :)

ask your host.

Gladiator it depends what OS/Distro you are running but it could be as simple as running:

yum install ffmpeg wget

That will work on RedHat / CentOS. If you're not the server admin then you'd need to speak to your host about this, they should be able to sort you out.

Your host admin should be able to resolve this issue for you, if not... you may want to consider another web hosting company.

wget typically comes with most distributions of linux. Do you have a dedicated server, a vps, or a shared hosting account? If you have a dedicated server, you should definitely be paying someone to manage it.
