This work for me: and took me a lot of time to find a proper way to stop gracefully the ffmpeg process

import ffmpeg, time

#Setup for recording windows desktop to mp4 file
process = (
            ffmpeg
            .input(format='gdigrab',framerate=25,filename="desktop")
            .output(crf="0",preset="ultrafast",filename="./output.mp4",c= "libx264" )
            .overwrite_output()
            )
#Launch video recording
process = process.run_async(pipe_stdin=True)


#Stop video recording
process.communicate(str.encode("q")) #Equivalent to send a Q

# To be sure that the process ends I wait 3 seconds and then terminate de process (wich is more like kill -9)
time.sleep(3) 
process.terminate()

Please consider add a wrapper/function to stop the process, or at least add some notes one this line to the readme or api documentation
