- LoadMPEG_adpro.ma written by Alex Kazik 1994
- LoadMPEG_HAM6.ma
- LoadMPEG_HAM8.ma

-
- ----- the idea ----------------------------------------------------------
- The idea of these three ARexx-scripts is to decode MPEGs. I got a decoder
- from the AmiNet, but it's not simple to handle it. To solve this problem I
- wrote these scripts, which are simple to handle.
-
-
- ----- the installation --------------------------------------------------
- The installing of LoadMPEG is very simple. MainActor must be installed,
- and an assign called "MainActor:" must exist. Just do a doubleclick on
- Install MPEGLoader "English", and it installes it automatically.
-
-
- ----- the operation -----------------------------------------------------
- To start the script, choose "Start ARexx-Script" in to MainActor from the
- menu "ARexx". Then choose the file "LoadMPEG_adpro.ma".
- First you get asked, which MPEG-anim shall be decoded. Then you get asked
- to give the name of the animation you want to make. If such a file already
- exists, give the same name again to delete it. If you don't want to erase
- the file enter another name or press "Cancel".
- In the next step the MPEG-anim gets splitted in seperate YUV-pictures,
- and the WB comes to the front and a window gets opened. In this window you
- can follow the steps.
-
- *** Remember the width and the height of the animation, which you get to
- *** know at the beginning of the decoding.
-
- After this is done, the pictures get counted. Then you are asked to give
- the original width and height, give the values that you have remembered.
- This is important, because the YUV-format stores only the simple picture-
- information without width and height.
- In the next step the YUV-pics are converted into PPM-pictures and then
- into 24bit IFF-pictures.
- Then ADPro gets loaded, if it is not already in the memory. It takes not
- more than 30 sec. to load ADPro. If it does not work you get asked if you
- want to wait longer . When you stop the operation the stored pictures get
- not erased.
- All settings get stored and at the and of the script loaded.
- Now you get asked, how the anim should look like. That means how many
- colours. You can choose between 2-256 colours, HAM and HAM8. Then it is
- asked if it is to calculate for every picture a new palette (UnLocked) or
- if the actual palette should be taken for every picture (Locked), or if a
- palette shall get loaded and be taken for every picture (LoadPAL). Now you
- get asked if ADPro should dither the pictures. You can choose between all
- ADPro dither-functions. If you choose "Random", "Lg Ord" or "Sm Ord" you
- can select the "DitherAmount".
- After all theese adjustments, ADPro starts working , and writes an
- IFF-Anim5-animation. When ADPro has come to an end, and it has been loaded
- you get asked if ADPro should be closed.
- If it is needed a new project gets opened, and the animation gets loaded.
- Thats all!
-
-
- ----- the two other scripts ---------------------------------------------
- The two other scripts decode a MPEG-Anim without using ADPro. The
- handling is the same as wich the other script, but the script creates only
- HAM6/HAM8 pictures, and there is no palette/dither function. At the end is
- no anim, only a list of pictures. You can save them to an anim.
-
-
- ----- at least: ---------------------------------------------------------
- The programms in the drawer MainActor:mpeg are from Andy C. Hung (Unix),
- ported to Amiga by Son H. Le. Thanks, because without this programm it
- would not have been possible to create these scripts. The original archive
- is in the directory mpeg in this packet.
- If you have problems with these scripts or new ideas or money or
- something else, please contact me.
