[Freedos-user] MPlayer: Tips and Tricks
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 3. (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 3 /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! P.

It's MS-DOS COMMAND.COM that was the concern. The trick works in batch files run by CMD,EXE under WinXP, too. I have a couple of batch files that use it. I'm allocating a RAMdisk with a compressed NTFS filesystem using a third-party driver on boot, loading my Firefox profile to it and having FF put its cache there. Firefox is set to look on the RAMdisk for the profile it will use when run. One batch file does the load, and another stores the profile back to HD when I'm done. Faster to store the profile in a zip file, unzip to RAMdisk to load, and zip back to catch changes in profile than to copy. __ Dennis -- Rapidly troubleshoot problems before they affect your business.

It's not official in any sense as there was (AFAIK) never a DOS/DJGPP maintainer for this. I never rebuilt it (probably a big pain) and have no interest in multimedia (nor patents, ugh), so I never even tried running it. You'd have more luck asking on BTTR's Forum. At least some of them have rebuilt this (or similar, e.g. FFMpeg) in recent years, e.g. RayeR or Khusraw. and old build from Michael Kostylev; http://www.ausreg.com/dos_ports/index.htm ; it seems that sources not exist in Web... Mik was notoriously bad about publishing his efforts, and he basically just disappeared. I'm not sure if he really ever meant to fully propagate any of it. So most of it just wasn't properly vetted. He was not really actively trying to volunteer for DOS communities. But that didn't stop people from keeping what little bits of his that they could find. Anyways, I know GPL sounds nice here (which I assume is why you're mentioning sources), but unless you're a glutton for punishment, you will not enjoy trying to rebuild such things. DJGPP is just not well-supported (upstream or downstream), so you're really swimming against the tide. Just use Linux isn't advice, it's a requirement since most *nix-y projects flat out refuse to even pretend to support DJGPP. 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 3 /dev/null %1 %2 %3 %4 %5 %6 %7 %8 %9 DJGPP supports response files, so mpoffi.exe @blah.txt should also work (esp. if you're going beyond 128 chars). I hope it is interesting for somebody :) Thank you, FreeDOS MPlayer maintainer! P. S: here is link http://freedos.10956.n7.nabble.com/DJGPP-Mplayer-build-tp19621p19627.html (not tested yet); Thank you, Mr. Georg Potthast! Again, it's probably not totally impossible to rebuild such things, but most of it doesn't work by default with DJGPP, and AFAIK there is no maintainer to any of this. Don't get your hopes up, what you see is (maybe) all you get ... for now. -- Rapidly troubleshoot problems before they affect your business.
