★ Sources: screen capture | camera | audio input | audio output This difference is caused by Wayland, a new desktop technology adopted by Ubuntu most recently and the Snap version is already successful to run on it.īelow's the options your can enable with OBS Studio:
#Ubuntu screencast to tv install
Screen recording indicator, if displayed then the screen is being recorded.įor Ubuntu version 20.04 LTS, do the following: $ sudo apt-get install obs-studioįor Ubuntu version 21.04 and above, do the following: $ snap install obs-studio.Status bar, where information about live recording / live streaming displayed.Controls area, where Start / Stop Recording buttons and Settings displayed.Audio Mixer area, the color indicators will move following audio input and output.Sources area, where you add / remove recording input items.Preview area, where you see what being recorded.I hope this blog post helps you in creating screen casts with the simplest possible tools. Note: I don’t use this extension in my example video though. You can also use a Gnome Extension called Draw on You Screen by Abakkk, with this extension you can do annotations directly on the screen and thus show your thoughts / comments / pointers on screen directly. I think it makes the screen cast a bit more entertaining compared to showing plain text but you can decide for yourself. Annotationįor annotation I use Xournalpp (xournal++) which helps me in drawing with my XP-Pen drawing tablet. You can minimize the settings pane so that you’re left with only the video of your webcam for the introduction/conclusion of your video. Install with sudo apt install guvcview, start the program with guvcview.
You can use the built in program CheeseĪnother option is to use guvcview, which has a cleaner interface (no buttons on the webcam output window) To add some engagement with whoever will view your screencast, you can show your own webcam in the screen.
You can also upload it to Youtube, which can process the output file and you are done to spread some knowledge! Add some extra spice to your screencast The result is what happens here: GIF recording of putting the video and audio together (Recorded with Peek GIF Recorder) This is the minimum necessary to create a screencast!įor example, you can send this webm video output file to people over email / file share / whatever you’d like. Specify the output file, in this case it will be copied to file.webm in the same directory as where you run the command. In this case it is 0:v to use the video for the first input file and 1:a to use the audio of the second input file The map itself shows what we are using in the output. The number is the first (0) or second (1) input file. Note that there are two input files (video & audio)ĭesignate one or more input streams as a source for the output file. To combine them, I used the following command: ffmpeg -y -i Videos/Screencast\ from\ 05-12-2021\ 02:51:06\ PM.webm -i Recordings/Clip\ 5 -map 0:v -map 1:a -c copy file.webm Right now you have two separate files, not really useful when they are not combined. When you stop the recording, the Ogg Vorbis file will be saved in the default location in your home folder, which is: ~/Recordings. Important: You need to press the screencast start keyboard command Ctrl+Alt+R and the Record button at the same time, or your video and audio will be out of sync. You can see me pressing the buttons in the recorded screen cast. Press “Record” to start your recording and click “Done” when you would like to end your recording. Audio recordingĪs the most simple solution I used the builtin Sound Recorder in Gnome: When you press Ctrl+Alt+R again, the circle disappears and the recording is saved to the Videos folder in your home folder: When the recording is in progress, you see a red filled circle in your notification area: Press Ctrl+Alt+R to start the screen cast recording. Since I want to use the most simple method, my approach is to use the built-in screen cast ability in Gnome. Written annotation on screen (Draw On You Screen).Written annotation on a page (xournal++).Putting the video and audio recording together.This howto is divided in several sections: In Pop!_OS I use Gnome with Wayland.Īll the instructions below will work with Ubuntu and any Ubuntu based distribution as well. I use Pop!_OS 21.04, which is based of Ubuntu. If you are very curious and want to see the result immediately, look at the video below: “Apache Kafka files store data without encryption”

Goal: Create a screencast recording of my desktop with narrated (recorded) audio at the same time. I was trying to use the minimum amount of tools in Gnome/Ubuntu and wanted to share the proces with you all. For a colleague I just made a screencast of a problem we were discussing.
