A look behind the scenes of FFmpeg of rudi - 19 Mar 2009 10:28:00
Some FFmpeg hate, some love it. For us, a life without FFmpeg in any case has become inconceivable. After recently quite surprising jump to version 0.5 took place, the site Phoronix three of the developer to load an interview. This will now be summed up online and gives some interesting insights into the development of the most universal codec pack of all time. For example, what is with the Hall of Shame on him.

Hello!

Nice article. And thanks for the hint.

FFmpeg is probably for the free video editing is now a non-core has become more firmly established. Much free but synonymous commercial software on Linux, Windows and MacOS X use FFmpeg or based on it.

Unfortunately, Michael Niedermayer with syllable None mentioned. He is the lead developer and has created FFv1 and snow.

Also, the diversity of the architectures supported are not mentioned. FFmpeg is running on almost all CPUs and synonymous to the so popular systems like iPod touch and iPhone.

A lot of greetings from here.
Lars

Hello together,

ffmpeg is really no longer inconceivable. Here's a thank you s.alle involved. In the new FAQ of VLC is that within Europe we do not pay royalties. Let us assume that you must pay royalties:
[list]
- Where do I pay the $ 2.50 s.die MPEG LA?
- Covers the fee, a software program, a person or even equal the entire budget?
- Do you have other codecs pay royalties?
[/ list: u: 10578a8e2e]

if I remember correctly, you pay per player. So for each installed software or a device, if the codec in hardware or firmware is realized.
Where you pay, I do not synonymous.
But who says that of the developed ffmpeg codecs synonymous with the specifications of the MPEG LA correspond, so that license fees at all costs?

Lars



Antwort von blenderman:

Hello Lars,

thank you for your answer. According to the old VLC FAQs should be due to patents in the MPEG ffmpeg royalties paid s.die MPEG LA. Although the implementation of a codec is. In the new FAQs are these charges in Europe according to the current legal situation does not become due. At least, I understood.

Nevertheless, I would be interested in how the $ 2.50 paid and whether other codecs of claims are concerned.

Regards,
Oli



Antwort von LarsProgressiv:

Hi Oli,

Patent rights and licensing are two different things!
Please do not mix.
Because of this problem I would prefer a synonymous of scratch-free and developed codec (FFv1 and snow), but there are too few developers who want and can.
Unfortunately, I can not synonymous.

Good night
Lars



Antwort von blenderman:

So I had understood that the claims from the MPEG LA license claims s.die user directed. The MPEG LA s.der are not involved in the development of ffmpeg. There was no code of the MPEG LA is used.

Some of the codecs that are distributed with VLC, are patented,
Royalty s.ihre why you have to pay the licensor. These are
Mostly the MPEG codecs.





Antwort von LarsProgressiv:

Good morning, Oli,

with the software patents in Europe is not, that is clear.

That with the licenses is something else. Each sold software or hardware that makes it possible, in a licensed format MPEG coded data reproduction are subject to licensing.

But If I remember correctly, private users are not burdened with the charges, but only companies that earn money with products that offer this possibility.

Surely I am not, because to me a few semesters in my Jura Vita missing ;-)

But if you get the license numbers really want to look doich times here:
