Playing Flash and Media Files Inline · **Released**: 03-16-2005

Is it possible? Is there any security issue? I am thinking of releasing this hack, but I am not sure about the demands and security issue on this.

History:

Originally, I have window media files played directly (inline) in phpbb. When I moved to vb, I tried to seek help from vb.com to modify their attachment system without success. I understand that Vb's attachment system for security purpose. Therefore, I have to find other means to achieve what I want. I come up with this hack when my board is at its infancy stage. It probably still is infancy because, it is used as a test and fun board when I am at work

.

Requirement:

This hack might not work on all system due to different configuration, platform, and such. I will try to help you all as much as I can.

This hack will use your board attachment system to run mp3, wma, wmv, flash files. It is a bit server intensive. So be warned

Security Risk:

It has been known that flash files can be used to exploit and compromise certain securities on user computer. You might want to verify your flash attachment before enable flash playing inline on your forum.

while i'm not sure about media files, flash files are a huge secruity risk i would suggest you note that in your initial post

montda · #14 03-17-2005, 11:28 AM

can i make it avelable to any usergroups i want?
it well be great

thx alot

Johnny · #15 03-17-2005, 11:48 AM

i dont get whats the difference from using just bbcodes for both instead of hacking the files

Deaths · #16 03-17-2005, 11:52 AM

Nice hack, wrong forum.

Show thread modifications would be more appropriate.

Mla7a6 · #17 03-17-2005, 01:09 PM

Hi..
It looks like a nice hack IF it will allow you to play ONLY media files (different formats: mp3, wav, wmv, au, rm, mov..etc.) because it is well known and tried before the security risk arising from playing flash files stored on your domain.. unless we can find a solution like to be able to store attachments on a different domain -or sub domain- and then try to call it from VB..
I am not a coder.. but I thaught 'll share my idea..

This hack uses attachment system on vb. You can set the permission there.

Flash files are cached to member's computer. If you don't want flash files being played on your board, then disable that section.

With bbcode:

You have to upload the files on your forum thru certain means like ftp, or the like.

Then you have to use bbcode for the link

With this one:

You use the vb built in attachment system.

you dont have to upload the files threw ftp to use the bbcode for a video or flash file you can just upload it threw the attachment system and link the attachment in the bbcode. i know it works that way on my board. :ermm:
