I have recently found a way to stream desktop grabbing with ffmpeg raw over my lan to a faster computer than the one I'm grabbing from and encode on the faster computer, so that I can do screen grabbing on a PC as old as my 1996/1997 200MHz pentium asus and encode it at a very decent rate for this hardware.
Some things can capture the sound as well, but some things can't.
For example, if I pipe the output of esdmon, and am running "esd zsnes" with some game loaded in the emulator I usually get pretty good sound rate.
I can't however, capture sound from wine yet.
Most of the problems I've run into doing this have been around my pre2000 hardware I am running the wine on under FreeBSD 8.2-release.
I wanted to go the easy way and set recording device to vol with alsa, or go with oss4 from packages/ports, but have not had success getting oss4 to work since the soundcard is an isa soundblaster awe64 pnp, and the vol recording device is unsupported on this hardware.
I almost got it working with padsp from pulseaudio, but it usually kills my userspace pulse daemon and the pulse is very laggy on my old hardware.
I have tried several other soundservers too, like arts, but no success yet.
Trying to record straight from normal FreeBSD 8.2-release legacy oss device gives a file is busy error since the sound has to be played to record from it.
I mostly use this PC for games and messing around with graphics stuff, anyway I am leaning towards a couple solutions:
-upgrading to latest FreeBSD-stable (I am in the process of doing a harddrive backup of my home and user data and will test latest stable with this hardware on another harddrive I might have handy)
-using a newer soundcard and going with oss4, I might be able to find a sbpci compatible card somewhere that will work with this machine, it has pci ports but the particular card happens to be isa
-using usb speakers that don't require a soundcard. If I have to spend money on this old hardware I'd rather do the usb speakers since I can swap them to other old machines - and newer ones, but I don't have much experience with usb speakers and have no idea which ones would work well with sound redirection I am trying to do.
I was really hoping I could get wine to work with esound's esddsp but when I do "esddsp wine" it just exits out with no explanation whatsoever and comes back up with sh terminal prompt instead of running wine at all.
If no one has a software solution other than upgrading to latest stable, then anyone in the know please give advice on the usb speaker way I am thinking of - what usb speakers work well and if they have sound redirection support.
I will try to post normal dmesg so you can see my hardware as well as pkg_info output so you can see software versions.
I just run this old machine as an extra home desktop, not a server somewhere that will have lots of security issues and stuff, so I don't mind changing permissions or something if I must or opening a firewall if that becomes a problem with this.
The one thing I haven't tried that I have available to me right now is trying to get wine to have alsa output (not sure if I can on this setup) and using arecord to do the audio grab.
Advice appreciated. Will try to attach dmesg and pkg_info outputs.
