Some hints, for FreeDOS lovers, or "HowTo Create a Nice Multimedia System
from Old Hardware"

MPlayer is two versions: official FreeDOS, with sources:
http://ftp.ibiblio.org/pub/micro/pc-stuff/freedos/files/util/user/mplayer/
and old build from Michael Kostylev;
http://www.ausreg.com/dos_ports/index.htm ; it seems that sources not exist
in Web...

"official" is more fast on old hardware, but it have a small bug: it can
freeze DOS, if play more than one file. For example, "mplayer 2.mp3" work
well, but "mplayer *.mp3" or "mplayer 2.mp3 3.mp3" freeze after first file
played. It seems to be hardware-depend bug, I'll write more guess-work
later... Build from Mr. Kostylev have not this bug.

I tested the "official" FreeDOS mplayer.

Hardware: NVIDIA Corporation NV11 [GeForce2 MX/MX 400] (rev b2), (64
MegaBytes); CPU: Celeron 1600 Mhz, all hardware from approximately 2002
year. FreeDOS is native.

First tip. Play excellent both AAC and MP3 audio tracks, up to 44 khz
stereo, but sometimes sound is "discontinuous". To avoid it, add "-af
resample 30000". (or 16000, or 8000....)

Second tip. Sound can be too quiet. Add "-softvol -softvol-max 1000" to fix
it, it make volume possibility to 1000%...

Third tip. Screen indication can be disabled, (it speeds up system): " >
/dev/null". Under DOS exist "/dev/null"? Funny....

Forth tip. You can create file "mplayer.bat" with all options in it.
here is my mplayer.bat: (mpoffi.exe is renamed "official" MPlayer)

c:\mpoffi.exe -softvol -softvol-max 2000 -af resample 30000 > /dev/null %1
%2 %3 %4 %5 %6 %7 %8 %9

well, what about HD video? MPEG, 1024x720, 24 fps, sound 44khz AAC/MP3
works well (with sound resampling, as above).
H264 works: 400x240, 640x360 - well. H264 800x480 (and more) -  can not
play at all, returns error: "first frame is no keyframe",  and another
errors, I'll play with it later, probably, play with "-vc something"?

Practically, all you need is graphics card after 2000 year; but unreliable
old video card can play 640x360 or at least 320x240 video pretty nice.

I hope it is interesting for somebody :) Thank you, FreeDOS MPlayer
maintainer!
