Flash is a very common format used to deliver animations over Internet. Flash brings us a lot fun but at the same time, flash viewers have to concern the security issues as well. The first flash file virus WF/LFM.926 appeared in early 2002 but was fortunately refused by patch tools emergently released from Macromedia company. However, just after two years in November, 26th, 2004, another new virus DJ2005 (Win32.Troj.QQMydj2005) which can be downloaded automatically with the flash file was found. When you are browsing the exquisite flash files, be extremely careful if another website is opened simultaneously or an irrelevant program is downloaded automatically, because that might be the virus! It can modify explorer. exe process and registry, besides, it can also send messages through QQ to cajole other users.

Strategies: first, scan DJ2005 trojans through free online virus check http://scan.kingsoft.com/; second, make sure your virus database is up to date to prevent any new virus; third, make sure your flash player, flash converter or other flash relevant programs are clean and safe, 100% virus free.

Now there are many teaching videos in the form of SWF spreading on the Internet. Quite useful, but how to watch those teaching videos under Linux operating system?

In fact, these SWF format videos are compiled flash bytecode files and can’t be played by regular video players like MPlayer and VLC Media Player, which otherwise is capable of playing other flash-delivered FLV files. Here comes the topic today: the introduction of three flash SWF players under Linux OS.

1. Swfdec

The earliest open-source flash implementation scheme, is able to play the most of flash 7 format videos and contained in almost all release repositories. Both 32 and 64-bit versions are available.

Installation under Fedora 10: su-c ‘yum install swfdec-gnome’

2. Gnash

Gnash is an emerging open-source flash implementation scheme, currently only supports flash 7 format videos. It’s quite active in the recent two year’s release, there are 32 and 64-bit versions.

Installation under Fedora 10: su-c ‘yum install gnash’

3. Adobe Flash Standalone Player for Linux

Adobe Flash Standalone Player was included in the Adobe Flash Debugger and can be downloaded from Adobe’s official website. There is only 32-bit version available but with the best SWF compatibility due to the official version.

Installation under Fedora 10: download and unzip with 7-zip, double-click the generated flashplayer icon to start. If you want to create SWF play association under GNOME, right-click any SWF file, choose “properties”-“open”-“add”, find and select the unzipped flashplayer, click “ok”. Then check the radio in front to make it the default SWF player, click “close” at last to quit settings.

4. Moyea SWF to Video Converter Std/Pro

Moyea SWF to Video Converter Std/Pro is a SWF player as well as a SWF converter which can convert SWF files to all kinds of popular video formats efficiently and swiftly.

Installation: click here to download and install the trial version for free.

5. Windows Media Player

Usually Windows Media Player can’t play SWF files under the default settings, however, if we manually change some settings, theoretically it can play. To be more precise, I’m still testing it and will write another blog about it when it’s done.

Summary

After the personal test using several English grammar SWF videos, Gnash sometimes may have the asynchronization between video and audio, Swfdec performs well, so does the Adobe Flash Standalone Player and Moyea SWF to Video Converter Std/Pro.

By the way, If you only have a few SWF files, those standalone flash players might be troublesome. In this case, what you need is just a web browser with flash plugin. Drag the SWF file to the address bar and that’s all it takes to enjoy your nice teaching videos.

Adobe company issued a statement said that it will cooperate with Google and Yahoo! to optimize the flash player technology, so that the flash content can also be searched by searching engines.

According to foreign medias, in order to add the genuine flash content to searching engine results, Adobe is working with Google and Yahoo! now to improve the quality of seaching results by providing the optimized flash playing technology. Adobe flash player advanced product manager Mr. JustinEverett-Church said this project will show the flash content searching results in the form of text and links. Flash-based applications, games, even the contents of advertisements shall be found by searching engines. The flash webpage made in .swf format also can be found easily. He also said: “the flash players will be installed in Google and Yahoo’s server so that they can play real-time flash files. This means the end-users will be guaranteed with better searching results. After all, searching online flash content is always a very big challenge.”

Mr. Vanessa Fox, editor of online media EngineLand, said that this cooperation can be a positive interpretation about how Adobe reacts to searching engines, but it takes time to judge whether it is profitable to do so. He explained: “searching engines are not able to grab any online flash content before. I’m holding a conservative opinion though I am optimistic about this technology. But honestly, still not sure how many webpages can be found by searching engines exactly.” It’s true that those flash-technology-based websites can obtain higher traffic, however, this project is only able to extract text and links from flash files, animations and videos are still not available.

The cooperation between Adobe and Google, Yahoo! will be continued to improve searching technology so that the publishers, developers, and users can all benefit from it. Delightfully, both Google and Yahoo! expressed their huge support for this project.
