Mp4 is the container. H264 is the video codec.

got me, it was DivX and XviD which are indeed newer and fancier than MPEG2

And still much easier to play than h264. A Pentium II with NetBSD was more than enough.

Nowadays on an n270 CPU based netbook I use mpv and yt-dlp capped to 420p, even if I can play 720p@30FPS.
