Why doesn't VLC player correctly indocate MPEG1 or MPEG2 video?

[Videogamer555]

Whenever I user FFMPEG to create MPEG1 or MPEG2 video (via the codec setting of mpeg1video or mpeg2video), and then play the resulting video file in VLC player, VLC player always indicates the codec as "MPEG-1/2 Video". Why doesn't it correctly show which MPEG codec is actually in use? It seems to indicate it can't tell which it is, so it indicates it as "1/2" meaning "this could be either MPEG1 or MPEG2". Can somebody here tell me if there's a setting in VLC player to fix this? Or is this a bug in the player's code?
