Roger's woze

just doing my part

ffmpeg windows

Here's how:

download script/run from http://ffmpeg.zeranoe.com/blog/

Then checkout FFMpeg source, then run:

./configure --enable-memalign-hack  --arch=x86   --target-os=mingw32    --cross-prefix=i686-w64-mingw32-  --pkg-config=pkg-config

The key here is the cross-prefix fella...that will change search for the file *gcc and see what your prefix should be.

make sure that location is in your path, too, I suppose (it should already be...)

c:\dev\ruby\downloads\rtsp-server>g:\installs\Perl\bin\perl.exe Makefile.PL
Set up gcc environment - gcc.exe (tdm-1) 4.5.1

It looks like you don't have either nmake.exe or dmake.exe on your PATH,
so you will not be able to execute the commands from a Makefile.  You can
install dmake.exe with the Perl Package Manager by running:

    ppm install dmake

Checking if your kit is complete...
Looks good

I think it just plain can’t.  Or if it can, I don’t know how.

It can output rtmp to a server, however (ffserver, red5, wowza, https://github.com/revmischa/rtsp-server)

http://svn.assembla.com/svn/legend/segmenter/segmenter.c might help…if ffmpeg eventually supports this

The trick is to use the raw mux–using ogg results in weird errors http://trac.videolan.org/vlc/ticket/3015#comment:7

like this (class LineEvent exists, Type is an inner, public class)

 Type = javax.sound.sampled.LineEvent::Type

The basic idea is to follow the trajectory of the eye, and, where the fovea centralis is looking, and to “beef up” the area that it happens to be looking at (and around the edges), thus giving the perception of ultra high resolution, while saving on bandwidth to transfer it.  +- having the peripherals also broadcast, and so they can look to their right or left and get the same type of ultra high density.

Oh,  and while I’m at it, you should do the same for movies, track some humans (or figure out how to anticipate where they’ll be looking, or tend to be), and focus more/most detail on those areas, per frame.  And/or areas of most movement.

Next idea: cup shaped monitors around the eye, so that it can give you a sense of periphery or actually being in a place, with or without the equivalent of several monitors being displayed in the cup.  Less priority there

Same thing for audio, basically several small speakers placed strategically so it can give the sense of audio being above or below or behind, etc. by it actually originating [kind of] from there, in the headphones.  Same with full sized speakers.

A monitor that broadcasts “out” at two different angles, one per each eye, so that it can give the illusion of depth.  Or camera shutters to allow only one to pass to each eye at a time.
