The video effects do not work with this configuration. This problem also applies to the VLC you can download via snapstore. On this VLC, I solved the problem by changing the "Hardware-accelerated decoding" setting to VA-API video decoder.
When I run the following code
import vlc
import time
def video(source):
vlc1 = vlc.Instance("--video-filter=Mirror")
player = vlc1.media_player_new()
media = vlc1.media_new(source)
player.set_media(media)
player.play()
time.sleep(10)
video("video.mp4")
I get the following messages:

I suspect I could solve this problem by changing the decoder, but I am ignorant of how to do so via python, and I am also ignorant of how I could learn to change this setting. Any help would be greatly appreciated. My coding experience is very low.
