[Quick Tip] Single Command to Rotate a Video in Ubuntu Linux

Last updated: February 9, 2023

Got a video playing upside down? Here’s an easy way to rotate it via a single command in Ubuntu.

There are a few video players, e.g., SMPlayer, support for rotating by 90 degrees clockwise or counter-clockwise during video playback.

If you want to make it permanent by exporting video rotated, besides using a heavy video editing tool, e.g., Pitivi and Openshot, the single command in this tutorial may help.

An upside down video

1. Install FFmpeg:

Firstly install FFmpeg if you don’t have it. FFmpeg is a large suite of libraries and programs for handling multi-media files and streams.

It is very popular and most likely already installed on your system, if you have any audio, video, and other multimedia relevant applications installed.

To make sure, open terminal (Ctrl+Alt+T) and run command:

2. Command to rotate video:

Now you can run the single command to rotate a video:

ffmpeg -i input-video.mp4 -vf "transpose=1" -acodec copy output-video.mp4

Before this command, you may first navigate to the video folder either via cd command (e.g., cd ~/Videos), or in file browser go to the folder and right-click blank area and select “Open in Terminal”.

In the command, the number in “transpose=1” can also be:

  • 0 – means rotate by 90 degrees counterclockwise and flip
  • 1 – means rotate by 90 degrees clockwise
  • 2 – means rotate by 90 degrees counterclockwise
  • 3 – means rotate by 90 degrees clockwise and flip

(Thanks to Roman Sheydvasser) Add -c copy (or -codec copy) will copy all the frames instead of doing decode -> filter -> encode process. It will speed up the command quite a lot!

In my case, the command is:

ffmpeg -i ~/Videos/aisha.mp4 -vf "transpose=1" -acodec copy ~/Videos/aisha-rotated.mp4

This command however will re-encode the video. Depends on the video size and your CPU, the process may take a few minutes.

Optional

The last command can take quite a few minutes since it needs to re-encode the video. As a workaround, user can use this command instead to do the rotation in the metadata.

fmpeg -i input-video.mp4 -map_metadata 0 -metadata:s:v rotate="90" -codec copy output-video.mp4

The command is fast and will work for video players (such as VLC and MPV) that support can handle rotation metadata.

Macchina – Another Command Tool to Display Basic System Info in Linux

Last updated: March 6, 2021

Macchina is another command line tool to fetch basic system information in Linux, similar to Neofetch, but focus on performance and minimalism.

The software is written in Rust, and it displays basic system information, including hostname, manufacturer, kernel version, uptime, desktop environment, processor, memory / battery status, and more. Macchina is pretty fast, it runs 8.53 ± 0.72 times faster than neofetch!

Macchina is a new project in active development. By adding --theme or -t flag, you can specify one of the supported themes. They are so far: default, alt, and long.

And you can specify the key color (--color / -c), the separator color (--separator-color / -C), let it show palette (-p) and display memory usage and battery percentage as bars (-b).

It also has options to change left padding and spacing.

How to Install Macchina in Ubuntu:

The software so far is available to install via crates.io.

1. Firstly open terminal and run command to install cargo:

sudo apt install cargo

2. Then install the tool via command:

cargo install macchina

Once installed, you can run ~/.cargo/bin/macchina with your desired flags.

If you prefer to use command macchina instead, run command to edit user’s profile:

gedit ~/.profile

And add following lines to add “.cargo/bin” directory to your PATH:

# set PATH so it includes user's private bin if it exists
if [ -d "$HOME/.cargo/bin" ] ; then
    PATH="$HOME/.cargo/bin:$PATH"
fi

Log out and back in to apply the new PATH.

Uninstall Macchina:

To remove the software via cargo, run command:

cargo uninstall macchina

If you don’t use cargo, simply remove it via command:

sudo apt remove --purge cargo

The default size of files and folders in Nautilus file browser does not meet you need? It’s easy to change it in all current Ubuntu releases with Gnome.

Though you can’t find how to configure it either in the System Settings or Gnome Tweaks, Ubuntu do provide an option to set an even larger or smaller icon size, and here’s the quick tip shows you how.

Here value ‘large’ can be changed to: ‘small’, ‘standard’, ‘larger’, or ‘largest’.

2.) Change icon size in list view:

gsettings set org.gnome.nautilus.list-view default-zoom-level 'large'

Here value ‘large’ can be changed to: ‘small’, ‘standard’, or ‘larger’.

To reset the change, either run command:

gsettings reset org.gnome.nautilus.icon-view default-zoom-level

or run:

gsettings reset org.gnome.nautilus.list-view default-zoom-level

Change file folder icon size via graphical tool:

Firstly open Ubuntu Software, search for and install dconf editor (or install dconf-editor via apt):

Then launch the tool and navigate to “org/gnome/nautilus/icon-view/default-zoom-level” for the icon size in icon view:

  • Turn off ‘Use default value’
  • Then select a size from ‘Custom value’

For the list view mode, go to “org/gnome/nautilus/list-view/default-zoom-level”.
