SGDK Video Player (work in progress)

[haroldoop]

Hello;

I am currently experimenting with creating a video player for the Sega Genesis using SGDK.

For now, I em just experimenting with what works and what doesn't; there are a few conversion scripts, but they aren't user friendly at this phase (version 0.0.1).

Example ROM for version 0.0.1: https://github.com/haroldo-ok/sgdk-vide ... .1.bin.zip
Github repo: https://github.com/haroldo-ok/sgdk-video-player

Version 0.0.2 tries to use raster ints to stretch the background vertically; it's still very glitchy.

Example ROM for v0.0.2: https://github.com/haroldo-ok/sgdk-vide ... .2.bin.zip

--- edit ---

I guess the vertical stretching idea isn't going anywhere; Instead, I will try to adapt the tech developed for RgbQuant-SMS into a command line tool that will perform tileset reduction for each individual frame and, if that idea works out, I may adapt it to reduce tile count between similar frames.

Version 0.0.3 uses RgbQuant-SMS to reduce the tile count of each individual frame.

Version 0.0.5 adds support for 320x224 resolution while not increasing the final compressed size very much.

Pretty cool. Not bad for an old 68000 and 16 color tile graphics.

Thanks!

Version v0.0.6 adds sound support, through SGDK's ADPCM driver.

Version 0.0.8 uses a newer version of "rgbquant-sms", that allows for faster encoding and much less RAM usage.

I made a few experiments with multi-frame merging, but it's still too slow and glitchy to be useful; branch with multi-frame merging experiment: https://github.com/haroldo-ok/sgdk-vide ... oup-frames

I think I'll leave the encoding as it is, for now, and start to turn the experiment into an actual tool.

Hello, again!

Version 0.1.0 refactors the disparate conversion scripts into a single coherent CLI.

To install:

Code: Select all

npm install -g sgdk-video-player

How to use:

Code: Select all

sgdk-video-player convert <src> <resDir>

Converts a video file and outputs the result in the resource directory

Positionals:
  src     The source video, the one that will be converted   [string] [required]
  resDir  The resource directory, where the generated sources will be placed.
                                                             [string] [required]

Options:
  --version                Show version number                         [boolean]
  --imagemagick-dir, --kd  Directory where ImageMagick is located       [string]
  --help                   Show help                                   [boolean]
  --cpu-cores              Number of CPU cores to use. If ommited, will use all
                           of them.
  --alias                  Alias to use when generating the C constants. If
                           ommited, it will be generated from <src>.    [string]

Now, all that remains for this being actually usable is to refactor the "main.c" file into a reusable library.

[haroldoop]

Version 0.2.0 refactors the video player into a SGDK-compatible C library.

Version 0.3.0 adds a flag to skip conversion if the files are unchanged.
