GoldenDict compiling without avformat (ffmpeg)

[embar]

Hi,

i would like to create GoldenDict package for openSUSE in OBS, but I can not use ffmpeg because of license. How can I compile GoldenDict with dissabled avformat (ffmpeg)?

Hi,

I don't think that it is possible to build without ffmpeg (without modifying the sources).

As far as I know, ffmpeg is (L)GPL and should not be of any problem license-wise. Why do you think it is unacceptable?

I can not found ffmpeg and libffmpeg-devel in open source repository of openSUSE – they are only in PackMan repository, witch can not be used in build.opensuse.org

Here's what is needed for Ubuntu, maybe it will be of any help to you?

Code: Select all

libao-dev libavutil-dev libavformat-dev

In openSUSE I found in default repository:

Code: Select all

libao-devel libavutil-devel

There is no such „libavformat-devel“ package. According this and this post, headers of libavformat is in „libffmpeg-devel“

But „libffmpeg-devel“ is in additional PackMan repository, that contain proprietary software.
And „libffmpeg-devel“ also exist in VLC repository.
But not in open source repositories of openSUSE.

Ok, got it.

I've file an issue here: https://github.com/goldendict/goldendict/issues/356

This is rather unfortunate. Even if we are to provide a way to build without ffmpeg, then GD won't be able to play sounds via internal player, you'd be required to use external players like vlc.

But I found ffmpeg package in OBS home:fabio_s project.
Now I successced to build GoldenDict from git
You can found this RPM package here: http://download.opensuse.org/repositori ... umbleweed/

Excellent!!!

What concerns me the most is that if ffmpeg by OpenSUSE definition is not 100% open-source then GoldenDict will never be part of the default installation.
