Very nice ... this might be useful for applications that want to capture some output or something alike.

I was looking for a way to have an visual DEBUG output for the FreeSpeedRacer 3D engine.
And yes it's nice for replays or demos too.

I don't think so it is really hot

No DirectX Medialayer or any VideoForWindows lib is needed.

neat, seems to get a lil choppy toward the end in wmp though, fine in mplayer except it looks fuzzy.
any chance of adding codec (xvid, divx) support? :D

Do you replay the avifile in original size?

the original replay recorder/player from FreeSpeedRacer used my fast de/compressor and the files end in *.FSR and it exist no codec for this types.

Feel free and add your codec support and write an player in FreeBASIC i think other people will love your work. but if you are do it do it not only for WINDOWS. I try to write all stuff for Lin and Win.

i found a free program on sourceforge which can add standard avi compressions to the output:
http://virtualdub.sourceforge.net/
free, and works very well. it reduced your program's output from 131mb to 500k with the xvid codec. ;)

D.J.Peters · Post by **D.J.Peters** » Sep 02, 2005 11:22

hi dumbledore,
yes for real movies you need an compressor / codec but i was made an loseless compressor.
I need it only to debug the 3d engine output from the FreeSpeedRacer project.
If any goes wrong with the 3d engine i can step later picture for picture to find the renderproblem.

When i use and codec with good compresion then many pixel ditals are lost.

Have a nice time and thanx for the link.
(it is only for Windows OS)
