[digiKam-users] fdk-aac support in appimage

Yes the ffmpeg build you use compiled with fdk-aac support.
The codec has a funky license though. I hope that is okay for digiKam.

Hi,
The difficulty about ffmpeg compilation is the huge external dependencies to solve to obtain the libraries.
Remember that DK AppImage is compiled under Centos6 for binary compatibility and ffmpeg is not avaialble by default. To compile ffmpeg i need to use external repositories not official and more and less maintained.
But, i use also ffmpeg at work to stream endoscope from the machine to Internet. I use also Centos, and i solved this problem recently by using a pre-compiled version of ffmpeg libraries available here :
https://sourceforge.net/projects/avbuild/files/

The advantage is to switch from ffmpeg 3 to 4 in appimage.
The disavantage is to not have any control on ffmpeg codecs available. You must use as well.
So please take a look at last 4.0.3 XV tarball for linux which contain the static ffmpeg binary. Look if the relevant codecs is available for you...

Hello Gilles,
I am wondering if you compile ffmpeg with fdk-aac codec within the appimage.Looks like the latest beta appimage can't play such files so I guess the answer is no.I have noticed that VLC, ffmpeg, Handbrake, etc. dropped fdk-aac support by default due to some licensing issues and was wondering what is your opinion on this.
I do have many videos coded using fdk-aac and I have to decide now on whether I recode all of them with another codec or just recompile ffmpeg, VLC and digikam myself.
Best regards, 
Andrey
