I'm tempted to revert that soonish, but I wanted to get an overview of
what issues the FFmpeg decoder has. Sorry for forcing testing on you :-)

I think you should be able to suppress it at least with the right -msglevel option.
Something like -msglevel decoder=-1
If it doesn't work that would be a bug I think.

Probably a good idea. I know we had this issue a few times in the past,
but I _think_ those cases have been fixed.

Yes, that's because ffmp3 is an integer decoder

Overall probably not after all. For now it was meant as a measure to get an
overview of the issues removing it would cause.
The speed one I could have found out myself, but for those overread issues
and also possible noise after seeking it's a matter of having the right samples.
