Short: Flash (SWF) format IBrowse plugin v.1.61 Author: 72207.463@compuserve.com (Mike Steed) Uploader: 72207 463 compuserve com (Mike Steed) Type: gfx/show Version: 1.61 Requires: 68020+; IBrowse 2.4+ Architecture: m68k-amigaos >= 3.0.0 Introduction: ------------- FlashPlayer is a player for Adobe's "flash" interactive animation format, also known as SWF. The flash format was originally invented as a very bandwidth-efficient means for delivering animation across the Internet. It has since grown into an interactive presentation format, complete with its own scripting language. Like most flash animation players for the Amiga, FlashPlayer is based on the open-source SWF library by Olivier Debon. FlashPlayer has made many improvements to the original SWF library, and has integrated it into an IBrowse plugin. However, despite the improvements, FlashPlayer still suffers many of the limitations of the SWF library, including limited or missing support for many of the newer additions to the flash format. This is the IBrowse plugin version of FlashPlayer. It works with IBrowse 2.4 or later to allow flash animations to be viewed as part of a web page. A standalone version of FlashPlayer is also available; it is capable of playing flash animations without the need for IBrowse. The source code for both the FlashPlayer plugin and the modified SWF library are available in a separate archive, FlashPlayerSrc.lha. Features: --------- - Fairly complete support for Flash 1 through Flash 3 formats Most of these older animations will play pretty much as intended. - Limited support for Flash 4 and up Does not support scripting, so while it will not malfunction when presented with a newer animation, it may not play it as intended. Newer animations may play just fine, however, if they don't use any of the unsupported features (I've seen Flash 8 and Flash 9 animations that work fine with FlashPlayer). - Fully integrated with IBrowse Flash animations appear as part of the web page, and can interact with the browser as well as the user to load other animations, visit other pages, and even execute Javascript. - Uses render.library and guigfx.library (included) for best image quality Plugins don't have access to the IBrowse rendering engine so, like the standalone FlashPlayer, the plugin uses these two libraries for its graphics output. This allows it to fully support any screen mode that IBrowse itself supports, including OCS, ECS, AGA, CyberGraphics, and Picasso 96. Uses dithering for improved display quality on color-mapped screens. - Uses AHI for flexible audio output Plays sound on any hardware for which AHI has a driver. Supports 16-bit audio. - Built-in decoding of MP3 sounds Contains an integrated version of the open-source MAD MP3 decoder; does not require mpega.library or other external decoder. - Support for alternate hardware platforms Because it does not depend on native Amiga hardware for graphics or sound, the FlashPlayer plugin works with Amiga emulators and with the latest Amiga hardware. - Configurable, for maximum flexibility Uses tooltypes to configure its operation (set the playback quality, enable or disable sound, streaming sound, and looping, adjust the sound buffer size, and set the diagnostic output level). New for version 1.61: --------------------- - This is an interim release that fixes a bug that caused the plugin to crash when loading a small number of flash files under OS4. There was no problem under OS3. - The plugin was compiled with optimization enabled, after it was inadvertently left off for version 1.6. - There is no corresponding version of the standalone FlashPlayer, as it has neither of these problems. Limitations: ------------ - Does not support many of the newer additions to the flash format Chief among these is the scripting language first added to Flash 4, and extended in newer flash versions. Some animations depend on scripting and will not run without it, while others use it only as an enhancement, and can still be viewed to some extent even without scripting support. - Limitations in the IBrowse plugin API As one of the first plugins for IBrowse, the FlashPlayer plugin uncovered some bugs and limitations in the IBrowse plugin interface. These will be addressed in future versions of IBrowse, but IBrowse 2.4 users will need to keep them in mind. Details are included in the documentation. - Resource-intensive While the flash files themselves can be small, decoding and presenting them requires lots of memory and lots of processor cycles. This is in addition to the cycles that IBrowse itself needs to download and present the rest of the web page. A fairly high-end system is required to make practical use of the plugin, and even a 68060 is unable to play most animations at their intended speed (or to play streaming sound without dropouts). - No printing The IBrowse plugin interface does not currently support printing, so printing (via Postscript) a web page with a flash animation will result in blank space where the animation is supposed to be. Requirements: ------------- The FlashPlayer plugin requires at least version 2.4 of IBrowse (earlier versions do not have an operational plugin interface). As does IBrowse, the FlashPlayer plugin requires at least AmigaOS 3.0, and a 68020 or better processor. The FlashPlayer plugin requires an FPU, and guigfx.library and render.library (both included). It makes use of, but does not require, AHI. The FlashPlayer plugin is not available for the PowerPC, as I don't have a PPC system to develop it on; however it runs under emulation on AmigaOS 4.
