compilation : libx264 and libx265

gheine
Hello,


Trying to recompile ffmpeg on a Linux Mint 18.3 system; currently  
installed version
is 2-3 years old and gives a lot of errors about libav1.

The Compilation Guide (trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu) states:

"If your repository provides libx264-dev version ≥ 118,
   then you can install that instead of compiling
....
  If your repository provides libx265-dev version ≥ 68.
   then you can install that instead of compiling"

Running "apt show" on these two libraries shows the following versions  
in the repo:
    lib264, Version  2:0.148.2643+git5c65704-1
    lib265, Version  1.9-3

Are these new enough to use in compilation ?

thanks for any assistance -

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.
