Just -zoom will make it do the right thing, but as you noticed software
scaling is really slow, especially without any assembler optimizations.
-sws options can make it a good bit faster, but still slow.

This is too old to do GLES (which if it worked might be the fastest way).

Why are you using gl2? gl is better in any aspect (except for supporting
some very, very old and special cards or videos with more than 2048x2048
resolution).

Also really old and a fork which is kind of off-topic here.

As said, the graphics driver sucks.
Get a up-to-date MPlayer version and try -vo gl:backend=3.
If it doesn't work, the graphics driver is not working properly at all.
Note: I don't think there is any way at all to make the graphics driver
work with an up-to-date Ubuntu for example.
