swf-projector

Package for creating Flash Player projectors

Overview

Creates Flash projectors from a standalone Flash Player.

Takes a standalone Flash Player file, a directory containing a standalone Flash Player, or a shockpkg standalone Flash Player package file.

Can also create bundles that group the projector and resources in a directory beside a single launcher for Windows and Linux or within an application bundle for macOS.

Reading DMG projector packages is only supported on macOS.

await projector.withFile('player.tar.gz', 'movie.swf');

await projector.withFile('player.tar.gz', 'movie.swf');

Bundle

Windows

import {BundleWindows32} from '@shockpkg/swf-projector';

const bundle = new BundleWindows32('bundle-windows32/application.exe');

// Use projector property to set options.
bundle.projector.removeCodeSignature = true;

await bundle.withFile('player.exe', 'movie.swf', async b => {
    // Add resources in callback.
    await b.copyResource('other.swf', 'other.swf');
});

Mac App

import {BundleMacApp} from '@shockpkg/swf-projector';

const bundle = new BundleMacApp('bundle-macapp/application.app');

// Use projector property to set options.
bundle.projector.removeCodeSignature = true;

await bundle.withFile('player.dmg', 'movie.swf', async b => {
    // Add resources in callback.
    await b.copyResource('other.swf', 'other.swf');
});

Linux 32-bit

import {BundleLinux32} from '@shockpkg/swf-projector';

const bundle = new BundleLinux32('bundle-linux32/application');

// Use projector property to set options.
bundle.projector.patchProjectorPath = true;

await bundle.withFile('player.tar.gz', 'movie.swf', async b => {
    // Add resources in callback.
    await b.copyResource('other.swf', 'other.swf');
});

Linux 64-bit

import {BundleLinux64} from '@shockpkg/swf-projector';

const bundle = new BundleLinux64('bundle-linux64/application');

// Use projector property to set options.
bundle.projector.patchProjectorPath = true;
bundle.projector.patchProjectorOffset = true;

await bundle.withFile('player.tar.gz', 'movie.swf', async b => {
    // Add resources in callback.
    await b.copyResource('other.swf', 'other.swf');
});

Loader Generator

To make it easier to create a SWF that loads another URL for use in a projector, there's a loader utility function which generates an ASVM1 stub which loads another URL into level 0 (effectively replacing the content).

You can also specify a number of frames to delay loading the other movie, to give the player a chance to initialize before loading the other movie. This is especially useful on Linux where the player may take about 0.25s to finish resizing the window and may not finish with the correct size (mainly depending on the desktop environment's use of the menu bar). Loading another movie into level 0 after the initial resize is done will however correct the issue. Waiting 0.5s (or FPS / 2) should offer enough of a buffer.

SWF8 600x400 30fps white movie that loads other.swf?param=1

import {loader} from '@shockpkg/swf-projector';

const swfData = loader(8, 600, 400, 30, 0xFFFFFF, 'other.swf?param=1');

SWF8 600x400 30fps red movie that loads other.swf, 0.5s delay

import {loader} from '@shockpkg/swf-projector';

const swfData = loader(8, 600, 400, 30, 0xFF0000, 'other.swf', 30 / 2);

Notes

Windows

Option: patchWindowTitle

An option to replace the window title stored in the binary. Size cannot be larger than the title being replaced in the binary.

Mac App

Option: patchWindowTitle

An option to set a custom window title in the binary. Size cannot be larger than the string being replaced in the binary.

Linux

Option: patchWindowTitle

An option to replace the window title stored in the binary. Size cannot be larger than the title being replaced in the binary.

Option: patchMenuRemove

An option to completely disable the menu for the projector. Avoids layout calculation issues when the menu is in the window.

Option: patchProjectorPath

Compatible with Flash Player 9+ (version 6 was correct).

Required since Flash Player 10.1+ to load relative paths (earlier versions would try the relative path first, before trying resolved path).

Projectors create the main URL with: "file:" + argv[0] resolving to a bad URL like file://file|%2Fpath%2Fto%2Fapplication causing relative paths to load from the root of the drive.

This patch replaces the string reference to use "file://" + argv[0] instead, which resolves to file:///path/to/application when run by an absolute path.

Not a perfect patch because it does not resolve the full path first, if run from relative path would get path like file://./application, but an improvement. Recommended to use a shell script or binary that resolves itself and runs projector from an absolute path. Using a Bundle does this automatically.

Option: patchProjectorOffset

The Linux projector reading code was never updated for 64-bit ELF compatibility. This patch fixes reading projector data in 64-bit Linux projectors.
