ssr-icon

Simple Screen Recorder, an open-source feature-rich screen recorder, sees a new release recently, almost one year after the last.

SimpleScreenRecorder is a screen recorder for Linux. Despite the name, this program is actually quite complex. It’s ‘simple’ in the sense that it’s easier to use than ffmpeg/avconv or VLC, because it has a straightforward user interface.

What’s New in the latest SimpleScreenRecorder:

  • Added support for latest FFmpeg/libav.
  • Make relaxed GLInject permissions actually work.
  • The backend now supports fragmented recording, but there is no GUI for this yet.
  • System tray icon now indicates errors during recording.
