Shift+Right Click in a folder (without any files selected) and choose Open command window here.Hit Win+R to open the Run utility and type cmd there.Search in the start menu for command prompt or just cmd.The 'terminated' event is emitted when FFmpeg is terminated by calling FFmpeg.terminate().Since FFmpeg is a command-line program, we’re going to need to open a command line! The 'completed' event is emitted when FFmpeg is successfully exited. The 'progress' event is emitted when FFmpeg reports progress. progress: a namedtuple with frame, fps, size, time, bitrate, speed fields.The 'stderr' event is emitted when FFmpeg writes a line to stderr. The 'start' event is emitted just before FFmpeg is executed. arguments: a sequence of arguments to execute FFmpeg.Gracefully terminates the running FFmpeg process. execute()Įxecutes FFmpeg using specified options and files. An arbitrary number of output files can be specified by calling this method multiple times. An arbitrary number of input files can be specified by calling this method multiple times.
