Command Line


player [-ao null] [-vo qt|gl|d2d|gdi|xv] [-vd "dxva[;cuda[;vaapi[;vda[;ffmpeg]]]]"] [--ffmpeg-log] [-f url|path|pipe:]

To disable audio output, add -ao null

Choose a render engine with -vo option(default is OpenGL). For example, in windows that support Direct2D, you can run

player -vo d2d filename

To select decoder, use -vd option. Value can be dxva, cuda, vaapi and ffmpeg, or a list separated by ; in priority order. For example:

player -vd "dxva;cuda;ffmpeg" filename

will use dxva if dxva can decode, use cuda if dxva failed to decode, and use ffmpeg if cuda can not decode.
