SimpleScreenRecorder is a Qt application for Linux that can record the desktop (Xorg only) and OpenGL applications directly. It had a major new release (0.4.0) about 3 weeks ago, but because I was waiting for its changelog to be updated (which wasn't until today), I forgot about it until today when a bug-fix 0.4.1 version was released.
The latest ScreenRecorder 0.4.0 / 0.4.1 brings high-DPI monitor support, a recording schedule, command-line control over stdin, and other improvements.
But first let me tell you a bit about SimpleScreenRecorder. The application uses libav/ffmpeg for encoding and it can record (with optional sound) OpenGL applications directly, the entire screen, a rectangle you draw on the screen or a window with properly synchronized audio and video, which is a common issue for other such tools. The video can be paused and resumed at any time, either with a click or with a keyboard shortcut. It also supports live-streaming, though this feature is experimental.
Other SSR features:
- good defaults
- fully multithreaded, so its various components don't block the others, resulting in a smooth video recording
- shows a preview during recording
- reduces the video frame rate if your computer is too slow
- shows a preview during recording
- shows statistics during recording, like the file size, bit rate, recording time, etc.
- tooltips for everything so you can fully understand what everything does
The new SimpleScreenRecorder 0.4.0 / 0.4.1 brings high-DPI monitor support. I don't own such a monitor, so I can't tell you how well it behaves with high-DPI monitors though. You'll have to give it a try and see for yourself.
The latest SimpleScreenRecorder also includes an important new feature: recording schedule. Using this recording schedule, you can set the application to start and pause the recording at a given date and time, so it can capture the screen without any later input from the user. This is great to record some TV show (in conjunction with a TV tuner) for example.
