[MPlayer-users] VO: Description: Null video output

In two separate blocks below, I have posted the outputs for
mplayer -vo help
and
mplayer -v Metallica\ -\ Nothing\ Else\ Matters.mp4
for the same user, but while running two different versions mplayer
under two different versions of RHEL.
The file .mplayer/config for this user contains a single line:
# Write your default config options here!
My video card is nvidia. The info about it from lspci is in my last
post (at the bottom of this post).
Now that you have explained a few things, I do not think I have an
mplayer driver for my video card.
With and without any of the command line -vo options, I get essentially
the same result. In what is posted below, I did not use them.
The version of mplayer that works under RHEL 7 is 1.1-4.4.7
The version I am trying to get to work under RHEL 8 is 1.5-8
The VO for the first version is reported to be Xv.
./configure for the two versions was run with the following options:
1.1-4.4.7
--enable-gui --codecsdir=/home/inatps/MPlayer/essential-2007100 --
prefix=/home/inatps/MPlayer/MPlayer2013 --yasm=
1.5-8
--prefix=/home/inatps/MPlayer/MPlayer-1.5/local --
codecsdir=/home/inatps/MPlayer/MPlayer-1.5/essential-20071007
The permissions for the two installs are the same.
At first, I thought the problem was an operating system permissions
issue. After some research, I thought is was a security issue with
ffmpeg. Now, I am of the sense it is a compile-time issue. I remember
that there is a compile-time log. Is that where I look next? Where do
I find it again?
Craig.
