What is meant by:
"You need a media player which is based on ffmpeg?"

How does the ffmpeg, affect the whole workings, of all the popular media players like WMP 11, WMP 12, VLC, etc?

How does the ffmpeg affect files, that may be end up on DVD media disc?

Thanks.

Here's their website: http://www.ffmpeg.org/   On the Projects page you can see products that use code from ffmpeg.  I don't believe ffmpeg is used in any of the Microsoft products.

It could mean that the media they're giving you requires something from the ffmpeg libraries and/or codecs.  Or maybe they just think it's better.  Since ffmpeg is a very large project with many branches, it would hard to say anything more without getting info from the person who said that.  The projects page lists at least 100 programs or projects that use ffmpeg software, none are from Microsoft.

What does it mean to be "Always On"?

I think what I mean to ask is this:

Someone said I needed, or might need, a media player based on ffmpeg.
In my orginal qeustion, I did not include WMP because I knew that ffmpeg had anything, whatsoever to do with WMP or Microsoft. I did not know whether it did or not.

So, the question should read:
Why would someone think I need a ffmpeg based media player?
You can use VLC or some other non Microsoft player forreference.
What about the media players would cause me to need an ffmpeg media player?
(as if ffmpeg is the "new" thing and will replace others - not sure, just using that as an example)

You can a lot of clues from the ffmpeg website but you can only get the 'facts' from the person who said that.  If you're looking at that freelance job, you will still end up having to ask them.

the person who said it was anonymous on Yahoo Answers.
My question was about a secific file format.
Before their answer, I had never heard of ffmpeg.
Now I see that is does mean "something" as far as media players, etc.

"what" I am not sure.

First, ffmpeg is Open Source which means a lot of people can use it.  Second, it has been included in a lot of projects (see their projects page) including some you are probably using.  And third, it appears they are trying to be a 'complete solution' when it comes to libraries and codecs.

ffmpeg is not the program but the internal coding that makes program run so you are less likely to see it's name.

adding points

When I asked my question it was about my file converter.
They suggested one, and when I went to download it, I got to a point in the installation where it gave a warning about downloading ffmpeg files.
I read the warning. The choices were either, yes or no.
I read the warnings carefully, and answered "no," I did not want to download
ffmpeg files.
So, I then tried to continue the installation.
The message appeared again.
It seems, that unless I answered "yes" that I would like to download ffmpeg files, the program would not work.
Since I read the warnings and did not understand ffmeg, I aborted the installation.

So, they felt the issues with my converter, was that I need one that supported ffmpeg and a media player that supported ffmpeg.


After readings the warnings involved with ffmpeg downloads, I said no.

What is it you don't like about the ffmpeg download?  I have it on several of my machines but I don't remember a warning.

I'll post the warnings...later when I can find them (if I can)
It was all "legal" jargon, copyright, and so forth.
It implied that ffmpeg was different than the rest.

the warnings about ffmpeg, implied, that ffmpeg downloads were risky, legally speaking.

If you're talking about the part where they say that they accept no liability for the use of their code, that would be standard practice in almost all of the user agreements for software.  Post a link to the original download that you were trying to get so I can see what you're talking about.  This is too vague this way.

Here is the download link:
http://download.cnet.com/Quick-Media-Converter-HD/3000-2194_4-10787822.html
I just went through the steps again. As with all programs there was a page where you agree to terms, etc.
Then right before completing the installation, it offers:
1. recommended installation.
2. custom installation.
Since #1 contained some "tool bar," I took the check mark out of the box.
Do not want a bunch of tool bars.
Then I clicked ok, or done. Then I get this:

And I do not know how to do a screen shot, control V and control C do not work, and my keyboard is 10+ years old.

Here is the entire warning:
Warning:
For the reasons stated below, FFmpeg is not installed, nor delivered with the Graphic User Interface Quick Media Converter (QMC)
QMC is just an advanced GUI designed for an open source program named FFmpeg. QMC is designed to essentially help you use the latter (Graphical User Interface) with ease and without command lines.

For legal purposes specific to each country:
We have therefore decided to leave you to the choice to install or not, the FFmpeg versions, you might need to convert your media files with QMC, during the installation process.

Note that this notice is also valid for all other applications using or containing FFmpeg that you might use or download and is not specific only to QMC.

Be aware that depending on your country, if you download FFmpeg you are susceptible to be subject to paying royalties on patented codecs such as MPEG2, MPEG4, AVC or other."
This in fact, depends on the legislation in your country. This aspect of things is not always clear or well defined and may vary from place to place.

Do you WANT to download FFmpeg files?

Yes and the installation of the program continues (the QMC converter).
No, and the installtion can not continue.
----------------------------------------------------------------------------------------
So, if I want to use QMC, I must say YES to downloading FFmpeg files though I have never seen an FFmpeg file, nor have any desire to download an FFmpeg file. Now if FFmpeg is the new thing in file format land, and will become standard then maybe I should say yes.
I said NO, because of the above warning, which I did not get with the download of my FoxTabAVI converter.

Also, I do not understand this:
"if you download FFmpeg you are susceptible to be subject to paying royalties on patented codecs such as MPEG2, MPEG4, AVC or other."

I've never heard of that.

And reading it, again, slowly, it says:
IF YOU DOWNLOAD FFMPEG then royalties are on patented codecs such as MPEG2 and MPEG4.

I've never known that FFmpeg files are in any way related to MPEG2 or MPEG4.

I wouldn't install a toolbar either.  What they are saying is that FFMPEG is the engine that does the work and QMC is the user interface.  If you look at the project page, you will see that FFMPEG is used by Google Chrome and the VLC player.

And there aren't any 'FFmpeg files'.  FFmpeg is a software engine that uses codecs like MPEG2/4 and others to generate and playback media files.  Some of those codecs are patented.  A 'codec' is a 'coder/decoder' that is used to translate from one format to another.  The simplest of codecs may be like one that splits an audio stream into left and right discrete channels for playback.  Others like MP3 codecs do a lot of math to decode the audio for playback.

If you are wanting to use this for converting your own personal files for your own use, you wont' have a problem.  If you are converting them for sale, especially in a mass market situation, then you might be asked to pay royalties.  If you are having them duplicated by a service then the service is usually the one who pays the licensing fees.

Here is the FAQ on MPEG licensing from Microsoft: http://www.microsoft.com/windows/windowsmedia/licensing/mpeg4faq.aspx   And here is a more general article: http://en.wikipedia.org/wiki/H.264/MPEG-4_AVC

........And there aren't any 'FFmpeg files'.

.........ok, but when they asked this question:
Do you WANT to download FFmpeg files?
and required a yes or no.....

It sure sounded like there were FFmpeg files.

My FoxTabAVI converter works fine.
Except it's only MPEG2 output format is MPEG2-PS (DVD VOB), and it will not play on my DVD player.

Some one said take the PS out. Well, I can not take it out.

So, that is when I asked someone:
Why won't my MPEG2-PS file play?
They said I needed an FFmpeg media player.
And I did not know what they meant by FFmpeg.
And they rarely come back to the question once they get the 2 points, so there was no asking what they meant. I just tried the QMC.

That means the FFmpeg program files.  There aren't any FFmpeg media files like there are MP3 or MPEG4.  If you want to do the conversion, go ahead and download the QMC and the FFmpeg program files.  You wont' be billed or arrested for making a DVD for yourself.

However... I dont' see anything on the QMC page about converting to DVD formats.  A Google search for 'video to DVD converter' brings up a lot of results including ones that say the convert and burn to DVD.  A 'real' DVD is not a computer file format, just like and audio CD is not.  If you put a video file on a DVD as a computer file, it probably won't play in any case.  You need a burner and/or converter that puts it in proper DVD format

This is all that was said.

..............."First off, I've used Quick Media Converter for about 2 years - great program, easy and free."

I downloaded it. and then run into the FFmpeg thing.
I had never heard of FFmpeg and then got warnings, etc. as I proceeded.

I don't see any problem with QMC and FFmpeg so if it will do what you need, I'd go ahead and use it.  If it doesn't do what you want, try one of the others.  There are quite a few to chose from.

Good luck with your project.
