- add 'ffmpeg' as the preferred provider for virtual/ffmpeg

to that provided by oe-core (e.g. kodi)

This needs more detail. What else would be providing virtual/ffmpeg,
other than ffmpeg itself? Why the justification is talking about
'different versions', and not different providers?

I was talking about versions, because thats what I use it for. A 
different provider would be e.g libav,but in meta-kodi I have older 
versions of ffmpeg
called ffmpeg-6 and ffmpeg-7 and let them provide virtual/ffmpeg. Dont 
ask me why I didn't stick with
preferred_version. I only remember that I had issues with using it but 
not exactly what it was. But if you think this
is the way it should be, I can give it another try

I think that was because I had to build Kodi and mpv with different 
ffmpeg versions at the time, because mpv was updated to ffmpeg 7 but 
Kodi wasn't ready yet.
Similar situation like today with ffmpeg 8. There exists a patch to add 
ffmpeg 8 support in kodi but to me it feels like its a bit to early for 
this step.

 couldn't find a way to use two different system versions of ffmpeg as 
long as they only differed in the version number.
