while I was trying out figuring some problems with playing videos from amazon.de I was wondering about the packages ffmpeg-free and ffmpeg-libs.
The package ffmpeg-free comes with the fedora repo and ffmpeg-libs is availible in RPM fusion free.
I first installed ffmpeg-free and after that I tried ffmpeg-libs (with removing ffmpeg-free).
Can you tell me what´s the difference between the two packages. Do they offer other codes for video playback?
ffmpeg-free includes only the FOSS/patent free bits of ffmpeg since Fedora does not distribute non FOSS/patent encumbered code. The RPM Fusion build of ffmpeg also includes the non-free/patent encumbered bits.
As stated, fedora can include ffmpeg, but only with the totally free codecs.
If you do dnf list ffmpeg* you will see all the packages available, and that only ffmpeg-free packages come from fedora. All the others are from rpmfusion.
audacity from fedora repository is built with audacity_use_ffmpeg=off to prevent loading of any ffmpeg libraries for import/export of restricted formats including mp4a.
audacity-freeworld from rpmfusion is built with audacity_use_ffmpeg=loaded and has it’s own compat-ffmpeg4 for import/export of mp4a.
Thanx! That was exactly what I needed. And, I put the question here instead of a new topic because just installing audacity isn’t enough; you need to know which version to install.
