FFmpeg-8.0 is ABI incompatible with 7.1. BLFS in the development books
has updated to FFmpeg-8.0. Several packages do not yet support
FFmpeg-8.0. Some of our own editing team have been bitten from
incompatibilites, such as:
1. Unable to watch live streams.
2. Unable to watch several videos and movies.
3. Unable to access healthcare portals.
4. Epic hangs.
5. Packages fail to build against FFmpeg-8.0 like MLT.

I estimate these issues won't get fixed for around another month. Thus,
I recommend to NOT upgrade to FFmpeg-8.0 to avoid a lot of headaches
and to ensure compatibility with all the software you currently use.

If you already upgraded or freshly installed FFmpeg-8.0 on your LFS
system, it would be a good idea to rollback to FFmpeg-7.1.

We may look into rolling back FFmpeg in the book. We pushed it out
in the book way too early.

I will send another email when the dust has settled and when it seems
mostly safe to install FFmpeg-8.0.

Apologies to any users with FFmpeg-8.0 currently installed as a result
of it being in the BLFS development (svn/git) book.
