I am not sure of what errors you are referring to.

Yes they are recent enough, but these packages are old and you would be missing
out on the newer changes (especially for libx265).
So although you can use these packages I recommend at least compiling libx265
instead of using the repo package: the guide provides instructions to do so.
Or if you don't intend on encoding using either of these encoding libraries you
can skip them and remove --enable-libx264 and/or --enable-libx265 from your
ffmpeg configure line.
