So where's their source code? Since they distributed it with ffmpeg, under the license agreement, they must distribute their app's source as well.
To clarify:
http://ffmpeg.sourceforge.net/legal.php
| Quote: |
Be advised that FFmpeg incorporates several modules that are covered under The GNU General Public License, notably liba52 and libpostproc. If you use these components in your project, you are expected to release your whole application under the GPL if you distribute your project at all. This is the full text of the GPL.

Q: Since FFmpeg is licensed under the LGPL, is it perfectly all right to incorporate the whole FFmpeg core into my own commercial product?
A: You might have a problem here. Sure the LGPL allows you to incorporate the code. However, there have been cases where companies have used FFmpeg in their projects, usually for such capabilities as superior MPEG-4 decoding. These companies found out that once you start trying to make money from certain technologies, the alleged owners of the technologies will come after their dues. Most notably, MPEG-LA (licensing authority) is vigilant and diligent about collecting for MPEG-related technologies.

This is why I haven't distributed MY PSP app yet....I wanted to wait for the other people to screw up first :).

... messed around with this app last night. seems pretty good. it uses the ID3 tags to create a thumbnail for the mp3 tracks, as well. however, it didn't on some tracks, some i'm wondering which version of ID3 it can handle.

Because we are not modifying ffmpeg, it is legal to package it with the software. It is not integrated via code nor modified in any way, there is no code to release, it is exactly the same as the usual ffmpeg release.
As for the ID3 tags, v2.4 tags should work.

It's not a question of modifying ffmpeg, it's the usage of it AS IT IS. This is why ffmepgX isn't distributed with the ffmpeg tool - the author tells the user where to get it.
I really think you should re-read the ffmpeg license.

Thanks, zigzag, for both of your quick responses ;)
Would be cool to see some .m3u file generation support too... not that the PSP supports it all that well (yet).

If the license is GPL, then I believe it works as I've stated.
LGPL offers even more freedom. Other applications already do the same thing we are doing and are considered fully legal. For example, take a look at Acquisition X, which uses the GPL'd LimeWire core.

We're already looking into it, among other things :)

Contradictory to your belief, by the way, ffmpegX *is* distributed with the ffmpeg tool. Please check your sources. Perhaps it wasn't in the past due to a misunderstanding by the author. |

I downloaded it 2 weeks ago and the tools were not there.

This does not mean the reason was licensing.
However, I've just downloaded it myself and they are included. |

You're right. My mistake. I cheked and it was there. I thought it wasn't because the "locate the tools" dialog came up when I first ran it, and it had URLs for the tools.
I'm a bit worried about distributing ffmpeg. I was reading the Debian distro forum where they had the same dilemma and they were going to point the user to where the tool(s) could be downloaded rather than distribute the tool.
I just don't want to pay a gazillion dollars in royalties someday :).

developers on *gpl onyl get cranky when you sell your app with thiers bundled in. take note that ffmpegX is free. i am not trying to knock this app, in fact i love it. more the reason for me to care about its future. if a large portion of this app is based on free code i would ask permission before it gets out of hand. best thing to do is have the app -require- ffmpeg installed, and make sure that your app gets licensed in a way to even be allowed to link against its libraries. (for instance: mysql4 and qpl code cant link eachother "legaly"... yet.. but thats another story)
hope this helps |

Developers only get cranky if you sell GPL code without providing the source.
It is ok to sell GPL code, as long as source is also provided, for the specific code covered under GPL.
If ffmpeg is GPL, they can include the code and binary in their shareware package, is is allowed under GPL.
As long as the code is not integrated with proprietary code, any separate proprietary code can remain proprietary. If there is any integration of proprietary source with GPL source, then all source must be GPL.
But they said ffmpeg is distributed as a separate binary, so I am not sure there is a problem here ? Unless the ffmpeg license is NOT GPL ? |

Good Lord. ffmpeg is LGPL, some optional parts of it are GPL, so if you don't use the optional GPL parts and don't modify the LGPL parts then you can distribute binaries compiled against ffmpeg without providing source to your entire app.
