Local preview backends:

Engine	Supported platforms	Required setup to achieve full functionality	Notes
Null	All	-	Just a mock. Does not provide audio nor video.
PyAV	Linux, Windows	-	Aimed to be the default on all platforms.
WinRT	Windows	Installation of some proprietary codecs (like HEVC). Codecs must be compatible with Windows Media Foundation.	Aimed to be phased out.
Qt	All	Installation of multiple codecs. On Linux GStreamer codecs. On Windows either DirectShow (default PyPI release) or Windows Media Foundation (default for binary release).	Aimed to be phased out.

FAQ:

Local preview does not seem to work (video/audio/both issue).

• First go to: Application > Settings > Local Player Backend
  
• Then try to choose a different backend.
  
• If PyAV backend is available on your platform, it should be the best option.
  
• If problem persists try to install codecs on your OS:
  • Linux - Install GStreamer codecs.
  • Windows:
    • Install codecs compatible with Windows Media Foundation. Most notably HEVC codec. Should be available in MS Store.
    • Install codecs compatible with DirectShow. Some codec pack like K-Lite should be enough.

I see no progress on taskbar on Linux.

Taskbar progress on Linux is supported only by selected desktop environments. (Like KDE or Unity.)

Furthermore, the application would have to be installed in either of root or user environment.

However, both approaches are discouraged and binary installation is recommended.

If you don't want the binary package, please use venv like so:

# Copy desktop and icon files to user environment:
cp -fv ${your_venv_prefix}/share/applications/* ~/.local/share/applications/
cp -fv ${your_venv_prefix}/share/pixmaps/* ~/.local/share/pixmaps/

# Create launcher script:
echo "#!/usr/bin/sh" > ~/.local/bin/kast
echo "source ${your_venv_prefix}/bin/activate" >> ~/.local/bin/kast
echo "python -m kast" >> ~/.local/bin/kast
chmod +x ~/.local/bin/kast

# Remember to replace all occurrences of the "${your_venv_prefix}" with an actual path to your venv directory!
