q3aql / ffmpeg-builds Goto Github PK

I want to download youtube video using ffmpeg tool and i took audio-URL and video-URL using " youtube-dl " but i wish to download particular video after 20 sec of duration from the start till end.
I don,t know what are the parameters that i needed to consider and how to do it ?
can anyone provide me related information to it .

I have previously used this script successfully on Centos6, but I recently upgraded my server to run Fedora 29, not sure what difference it makes, but when you cd ffmpeg-* on line 126 it errors as there is also ffmpeg-url and the xz file

Also, there is no ffmpeg-10bit in the xz, I fixed it on my local copy, PR to follow

1. I would like to install an older build

https://www.johnvansickle.com/ffmpeg/old-releases/

https://www.johnvansickle.com/ffmpeg/old-releases/ffmpeg-3.3.4-64bit-static.tar.xz

2. I did all the first steps below,

`How to install (ffmpeg-install):
Instructions:

Open the terminal.
Clone the repository: git clone https://github.com/q3aql/ffmpeg-install.git
Change directory: cd ffmpeg-install
Copy the script to $PATH (as root): cp -rf ffmpeg-install /usr/bin/
Change the permissions (as root): chmod +x /usr/bin/ffmpeg-install
Note: The script are compatible with all GNU/Linux distributions.`

now what would i type in the command line in ssh to get it to install ?

i tried typing in command line :

ffmpeg-install --install
and 
ffmpeg-install --install release

./ffmpeg-install --install
and 
./ffmpeg-install --install release

but get keep getting error below?

`Downloading (wget)
wget: missing URL
Usage: wget [OPTION]... [URL]...

Try wget --help' for more options. Connection problem! Exiting...

can you explain to me in simple words, if i need to edit some code in the ffmpeg-install file
also exact command in the ssh i would need to type to get it to install ffmpeg

Thanks for the help and sorry im a newbie to this stuff
