Looking to implement a small BigBlueButton server but leadership is asking about whether any royalties/fees need to be taken into consideration.
In particular, BigBlueButton recordings are in MP4 format so they are wondering whether any H.264 & AAC encoding royalties are required? Any point in right direction is appreciated.
You would need to only pay royalty fees if you are charging for content, if you are not charging for content then H.264 is free to use see this release.
Also bigbluebutton does not use H.264 encoder/decoder even for playback as it respects the commercial license agreements and supports only WebM for this( from version 0.81 the latest), so you don't need to worry about the same (See this discussion about H.264)

I noticed that WURFL changed his license model on 30 august 2010. Can please anyone explain me, can I use it with new license in commercial product?
See licensing info for commercial use at ScientaMobile
A cloud offering should be making it's debut in roughly a month, and may save you some $ depending on your usage. A free version with limited capabilities will likely be included as well.

I'm looking for a non-(L)GPL library to decode MPEG-4 stream.
I don't mind it being commercial.
The price is as not important as code quality and support.
Any suggestions are welcome.
Your own experience is even better.
You can only try Commercial ones:
Elcard : http://www.elecard.com/en/download/products.html
Ligos : http://ligos.com/index.php/home/products/mediarig_encoder/
MainConcept : http://www.mainconcept.com/products/sdks/video.html
Rohzet (carbon coder) : http://www.rhozet.com/products.html
Flip factory : http://www.telestream.net/flipfactory/overview.htm
All of these are practically well used in broadcast productions and are of good grade.
The order doesn't reflect any preference. Most of them are either usable as SDK or independent application with dongle or otherwise.
However, your fear is rather fundamental, and fleeing DLL might not be possible to be prevented trivially.
I was under the impression that CoreAVC is by far the best performant H.264 codec. http://corecodec.com/products/coreavc
Depends what you mean by non-GPL. There are many that are LGPL (thus non-viral).
Like the most popular one libavcodec which is part of FFmpeg.
By contrast x264, which is GPL-ed, is only needed for encoding, not for decoding.
FFmpeg makes it clear how to compile it in non-viral way.
Are you going to require your own videocard drivers as well, or what happens if I use a video driver that does whatever I want with what your decoder sends me? Are you going to somehow force users to use only your video cables as well, and somehow destroy any video camera in the vicinity, and wipe clean the users' memories of what they see? Such madness! So what if you use a GPL library? You cannot lock down the Universe.

I seem to recall hearing at some point (I believe it was MIX09) that Microsoft has a licensing model of some sort where a business can consume licenses for up to two years, free of charge, until they reach a point where they are stable position and can pay their licensing at the end of two years. However, I can't find information regarding it online.
I want to say that possibly stackoverflow used this licensing model to kick start their site. Is anyone familiar with this?
In addition to BizSpark (as per #paul) there are also WebSpark and, as of May 2010, the developer MAPS programmes.
Webspark information is here: http://www.microsoft.com/web/websitespark/default.aspx
Details of the Action Pack (MAPS) are currently here: https://partner.microsoft.com/global/40132997
I'm fairly certain that in all cases availablility varies by your location - but if you're producing stuff for/with/on Microsoft tools/platforms then they're all worth a look.
You're thinking of BizSpark:

There is also the Empower program if you're an existing business, not a startup.

I want to create a project using DirectShow. Which license does DirectShow have? Can I just use it or do I have to mind sth.?
What input and output-codecs can DirectShow handle?
You can just use Directshow with no issues. The only issues you may have surround some of the codecs. Some of those are licensed. Distribution of those "can" get complicated. In general (Though this isn't always the case so make sure you check the license!) decoders can be distributed freely but encoders need to be licensed in some form of other.
As for what input and output codecs it can use ... it can use pretty much anything with a DirectShow or DirectMedia Object built for it. If there is a format there is usually an encoder/decoder for it.

its not directly programming question
but i need to implement ffmpeg functionality in my application that is commercial.
what is my restrictions when using this lib/app ?
i was confused from reading there web page .
"FFmpeg is free software and is licensed under the LGPL or GPL depending on your choice of configuration options." from the homepage.
The mini-FAQ at http://ffmpeg.org/legal.html should probably answer your questions. Do you have a specific part of it you don't understand?
http://ffmpeg.org/legal.html
That sums up all relevant information quite nicely.
I would say that if you want to incorporate FFmpeg into your commercial application, you should consult a lawyer who is familiar with the laws and regulations in your area and the area in which you wish to distribute your application.
