Transmission-daemon on Archlinux ARM

Setting up Transmission-cli on Archlinux ARM

1-Install transmission-cli wich provides transmission-daemon

# pacman -S transmission-cli

2-Start the transmission daemon, as your regular user type:

$ transmission-daemon

3 – On a web browser type http://127.0.0.1:9091 to see the web client.

4 – Stop the transmission-daemon, it’s needed so changes to settings file can be saved.

5 – Edit the configuration file

$ vi /var/lib/transmission/.config/transmission-daemon/settings.json

Important changes can be:

“blocklist-enabled”: false,
“blocklist-url”: “http://www.example.com/blocklist”,
“download-dir”: “/var/lib/transmission/Downloads”,
“pidfile”: “/run/transmission/transmission.pid”,
“rpc-authentication-required”: false,
“rpc-bind-address”: “0.0.0.0″,
“rpc-enabled”: true,
“rpc-password”: “{634e22dd6343fb51a74b74183cfca5e9a1458f24yP/vrXE.”,
“rpc-port”: 9091,
“rpc-url”: “/transmission/”,
“rpc-username”: “youruser”,
“rpc-whitelist”: “*.*.*.*”,
“rpc-whitelist-enabled”: false,

Make sure user transmission has rw permissions on the Download-dir and also change permissions of the directory of pidfile

# chmod -R 777 ‘/run/transmission’.

6 – You can now start the transmission-daemon again to see the changes

Normally the installation will create a user and group named transmssion, and the transmission-daemon will run as the user transmission, whose home directory is /var/lib/transmission/.

And the configuration file is /var/lib/transmission/.config/transmission-daemon/settings.json.

I) If you want to run transmission-daemon as your normal user (or any other user), stop the transmission-daemon.

II) Start the transmission daemon, as your regular user type:

$ transmission-daemon

This will create the directory .config/transmission-daemon

III) Set up your settings there:

$ vi $HOME/.config/transmission-daemon/settings.json

If you want to run transmission-daemon as a service in systemd

Copy the service file and the tmpfile to systemd

# cp /usr/lib/systemd/system/transmission.service /etc/systemd/system/
# cp /usr/lib/tmpfiles.d/transmission.conf /etc/tmpfiles.d/

Make sure the group transmission is created:

# groupadd transmission

Add user to that group:

# gpasswd -a [user] transmission

Change service file

# vi /etc/systemd/system/transmission.service

Change User= to your user

Edit the tmpfile to the following:

# vi /etc/tmpfiles.d/transmission.conf

/etc/tmpfiles.d/transmission.conf
d /run/transmission – [user] transmission -

Make configurations:

# systemd-tmpfiles –create transmission.conf

Reload service files:

# systemctl daemon-reload

You can now use transmission-daemon as a service in systemd

# systemctl start transmission.service

If you would use Transmission daemon with its own group, you have to give the writing permission to transmission group in your download’s directory:

# chgrp transmission /path/to/download # chmod g+w /path/to/download

RaspberryPi – Raspian play full HD movies

Is it possible that such a tiny thing with only 512 mb,  to play a full hd movie 1080p with no lags?

Yes it is, the trick is to use to the Raspberry Pi’s GPU. Omxplayer is a video player specifically made for the Raspberry PI’s GPU made by Edgar (gimli) Hucek from the XBMC project, basically it takes advantage of the hardware acceleration to play videos.

1. Install omxplayer (it may be already installed), also install x11-xserver-utils

sudo apt-get install omxplayer x11-xserver-utils

x11-xserver-utils will give you the program xrefresh

2. Play a movie inside a (X11 environment) using hdmi

omxplayer -o hdmi /path/to/movie_1080p.mp4

omxplayer options

omxplayer –help

Usage: omxplayer [OPTIONS] [FILE]

Options :

         -h / –help                    print this help

         -a / –alang language          audio language        : e.g. ger

         -n / –aidx  index             audio stream index    : e.g. 1

         -o / –adev  device            audio out device      : e.g. hdmi/local

         -i / –info                    dump stream format and exit

         -s / –stats                   pts and buffer stats

         -p / –passthrough             audio passthrough

         -d / –deinterlace             deinterlacing

         -w / –hw                      hw audio decoding

         -3 / –3d                      switch tv into 3d mode

         -y / –hdmiclocksync           adjust display refresh rate to match video

         -t / –sid index               show subtitle with index

         -r / –refresh                 adjust framerate/resolution to video

 

Sometimes after playing a movie the screen will become all black, using xrefresh will get it normal again:

xrefresh -display :0

Spotify on Fedora (and others)

Spotify is more than a music player, is a digital music service that gives you access to millions of songs. It works on your computer, your mobile, your tablet, and your home entertainment system.

The features that makes this my music player over iTunes are:

1. It has a Windows and a Linux version, which is great if you’re forced to work and Windows at work like me;
2. It has a free version (with an advertising bar);
3. It works with iPod’s;
4. It has thousand of musics and artists;
5. It can uses both iTunes and Windows Media Player libraries;
6. It connects to Facebook, adds your friends and let you see what they listen to

 

Unfortunately the official package for the Linux version is .deb, to get it working on Fedora, there’s two ways:

The easy one

Fedora 18 (64-bit):

1. $ sudo yum install http://trash.ulyaoth.asia/trash/rpm/spotify-client-0.8.8.323.gd143501-ulyaoth.fc18.x86_64.rpm

Fedora 18 (32-bit):

1. $ sudo yum install http://trash.ulyaoth.asia/trash/rpm/spotify-client-0.8.8.323.gd143501-ulyaoth.fc18.i386.rpm

Thanks Sjir Bagmeijer

 

The hard one

Transform the .deb into a .rpm

For Debian/Ubuntu

 

Debian
# 1. Add this line to your list of repositories by editing your /etc/apt/sources.list

deb http://repository.spotify.com stable non-free

# 2. If you want to verify the downloaded packages, you will need to add our public key

sudo apt-key adv –keyserver keyserver.ubuntu.com –recv-keys 94558F59

# 3. Run apt-get update

sudo apt-get update

 

# 4. Install spotify!
