Licensing for most of the apps you mentioned is a bear.
MP3: Playback licensing is required and costly. $10,000.00 (Unless the
underlying technology is licensed). In Windows, it is cover under
directx for PLAYBACK only. There is no provision for Mac as far as I
know, please tell me if I'm wrong. I would love to know.

JPEG: http://en.wikipedia.org/wiki/JPEG
As of October 6 </wiki/October_6>, 2006 </wiki/2006>, the U.S. patent's
20-year term appears to have expired, and in November 2006, Forgent
agreed to abandon enforcement of patent claims against use of the JPEG
standard.^[6] <#_note-surrendered>
The JPEG committee has as one of its explicit goals that their standards
(in particular their baseline methods) be implementable without payment
of license fees, and they have secured appropriate license rights for
their upcoming JPEG 2000 </wiki/JPEG_2000> standard from over 20 large
organizations.
Windows Media Technologies: Licensing is free under Windows but not free
on any none-windows platforms including the Mac.

By the way, I would love to know if RS is paying for usage of the
players on their development engine. The thing is that RS is not the
developer of the application, you and I are, so I would love to know
what licensing if any is covered by RS.

No, I do not believe there are any royalties for playback of Windows Media
files. REALbasic includes built-in support for Windows Media Player from
their MoviePlayer control. The MoviePlayer control accesses the ActiveX
version of Windows Media Player, which I believe is already installed on
people's PCs if they already installed Windows Media Player. Microsoft
offers the API documentation for .Net, VB, and any other development tool
that can access the Windows Media Player API.
Usually, only the creation or saving of proprietary file formats is when
licensing or royalties come into play. Unisys used to have a patent on the
GIF format and they went after developers whose applications saved files as
GIFs. There's also a patent out there for MP3, which requires a royalty for
encoding/creating MP3 files. Awhile back, Forgent was actively pursuing
developers for apps that save JPEG files. I know their JPEG patent came
into question, so I'm not sure what the final verdict on JPEGs are...
But if your application only reads or plays those formats, then I do not
believe there are any licensing or royalty issues.

I saw u gave an URL to the sdk doc and was hoping you had found better
information on distribution.
Does MS make app developers pay royalty for playback?

Giovanni,
Not sure what you mean by that... If you're referring to Microsoft's free
version of Flip4Mac QuickTime component, I do NOT include it with Stimulus.
Stimulus users are encouraged to download that component themselves if they
want Windows Media support in QuickTime. So there's no distribution
licensing needed since I don't distribute it with Stimulus.

Actually, Microsoft offers the free Windows Media Component for QuickTime by
Flip4Mac for Mac OS X (they had acquired the free version from Flip4Mac).
It can be downloaded free from:
<http://www.microsoft.com/windows/windowsmedia/player/wmcomponents.mspx>
That solves playing Windows Media files using RB's QuickTime movie player
control in Mac applications.
As for playing both Windows Media files and QuickTime-compatible files in
Windows applications, this is what I did in the Windows version of Stimulus:
(1) -- First my code determines what filetype the selected media file is.
(2) -- If its a filetype that will play via QuickTime, then I set the Movie
Player control's PlayerType property to 1 (QuickTime). If its a Windows
Media file, then I set the MoviePlayer's PlayerType property to 2 (Windows
Media Player).
(3) -- If you have a media file whose filetype that is compatible with
either QuickTime or Windows Media Player, I usually opt to play it with
QuickTime since RB's MoviePlayer control is the most reliable with QuickTime
as its PlayerType (in my humble opinion). I found that the best way to
control the Windows Media Player (via the Movie Player control) is to access
the methods and properties of the Windows Media API via the Movie Player
Control. Here's the URL to Microsoft's online docs:
<http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wmpsdk11/m
mp_sdk/windowsmediaplayerobjectmodelreference.asp>
Brian, before you ask...
Stimulus is a commercial application, so unfortunately, I'm not at liberty
to share the above mentioned code with you since it represents a huge chunk
of functionality.
But I have been thinking about rolling that Windows Media and QuickTime
functionality into an easy to use encrypted RB class. If anyone's
interested, send me an email offlist, so I can gauge the level of interest.

Dave Wooldridge

What platform? Windows or Mac? If you're going to be running on
Mac, have you tried Flip4Mac which allows QuickTime to player WMV
files (up to version 9, 10 has some DRM stuff which renders it
unplayable on Mac as MS hasn't seen fit to release WMP 10 for Mac)
Otherwise, I'm not sure how you would pull this off without WMV
codecs for QuickTime... and there isn't a "WMVPlayer" control in
REALbasic that I know of.
Note that Flip4Mac (http://www.flip4mac.com) isn't free, but isn't
that expensive if you just want to play WMV files under QuickTime;
it's somewhat pricier if you want to edit it though.

I am building a media player application
I want to open a
1) QuickTime Movie File
2) Windows Media Movie File
How would I go about doing that?
Do I need to know the file type(s) and creator code(s)?
or any kind of file extension? If so what are they?
I got a Movie player control in my project
