Section 12.3.3 Worth testing out?

Convert to AVI first with ffmpeg

Code: Select all

for i in ../rips/unmodified/aitd4/cd2/AITD4_GD_2/MOVIES/*.4XM; do ffmpeg -i "$i" -vf scale=320x160 -y "${i%.*}.avi"; done

Downsample with 4xm_comp.exe

Speed : 30 fps Data Rate : 110000 Resize Width 320 Height 160

Yes, thank you moefoh.

Thanks for the shout out SMiTH. Never got Cred before. I did a thing! Feels good.

Nice work on the script. Might you edit your first post with it? So it don’t get buried? 19 pages is a lot to wade thru..

Next I wanna test the multi launcher GINSU. To see it work with more than one 4x vid.
For science.

Here is a quick test using the 4xm selfboot script v4...

Fight Club Trailer 4xm test:
https://mega.nz/file/QYpGUSyI#JqOGAvix6 ... XbISw-_ID4

source:
video codec: xvid-avi
(viewed in file properties, details tab)
width: 1280 height: 720
datarate: 100000
total bitrate: 101411kbps
fps: 30
audio: 1411kbps, 44 khz, stereo

4xm_comp:
resize width: 320 height: 160
speed: 30fps
data rate: 800000

testing another 4xm with different settings, will post later..

That works but it is the same spec as softdec.. This spec is what they used in the games that used it..

There are 2 version of 4xm player one is the c player it can use Ginsu and the C++ version which can not use it at all..
I have my katana dev and wince set up so we can make changes to the player..

Current every version is set to scalex=640.f/app_handle->width;
scaley=480.f/app_handle->height;

Dont save any thing far as speed using 320x160 this was for space on a retail game..
It still drawing 640x480 to the screen..

Sample player on dreamon is crippled version
config->memory_cache_size=128; // we ask 128 pages (256Ko pre-buffer); default is 1024 only set to 128k pre buffer

4x Movie player - DreamCast Version
   (c) 4x Technologies / 2000
---------------------------------

1 - C

In the directory C, you can find the player working in full C. So, it supports SHC, GNU and MetroWerks CodeWarrior.
To build the SHC or GNU version, open the makefile and change the compiler option, and run gmake on the command line.
To build the CodeWarrior version, go in the subdirectory cw and open the mcp project.

2 - C++
In the directory C++, you can find the player working in full C++. So, it supports GNU and MetroWerks CodeWarrior. But the SHC doesn't work at all.
To build the GNU version, run gmake on the command line.
To build the CodeWarrior version, go in the subdirectory cw and open the mcp project.

3 - Note
The source code of the player is only here to show how the 4xmovie sdk works. You can modify it for your own use.

This thing where using is basic sample of 4xm sdk..

So the multi launcher GINSU works with more than one Video. Here is a quick and dirty example:

I'm guessing Dreamon should work too? I will have a look

[-drez01-]

Dreamon works. You just play the videos the same way as with GINSU, but using Dreamon's menu system. Have to add it to the MENU.CFG. Plus each Vid needs its own CFG
