I checked the ffmpeg encoding as not found libx264, but it wasn't in /usr/lib/, so I tried to install it, but I couldn't do it many times, so I asked this question.
I downloaded x264 on git clone and compiled it.
However, after doing the above, x264 was added to /usr/local/bin/ instead of /usr/lib/.
Is this the wrong installation?
Also, even if I can install libx264, can I use ffmpeg right away?
Do I need to compile ffmpeg again after I put it in?
Thank you for your cooperation.
Additional information
The operating system I use is raspbian.
configure results are
platform:ARM
byte order —Little-endian
system:LINUX
cli —Yes
libx264—internal
shared —no
static —no
asm —Yes
interlaced —Yes
avs —avxsynth
lavf —Yes
ffms —no
mp4 —no
gpl:yes
thread —posix
opencl:yes
filters —resize crop select_every
debug: no
gprof —no
strip —no
PIC: no
bit depth —8
chroma format —all
It came out like this.
The results of the make are as follows.

I tried configure, make, and make install.
However, this was not found in /usr/lib/ and only added x264 to /usr/local/bin/.
The configure option does not have --enable-shared so only the execution commands are built.
Specify --prefix=/usr if you want to change the installation location.
Also, even if I can install libx264, can I use ffmpeg right away?

It's a shared library, so I think it's okay.
However, you can't try it, so please check it yourself.
How to verify the configure option
configure has options, so check the options you need as follows:
$./configure --help
Is there an option around here?
--prefix=PREFIX install architecture-independent files in PREFIX [/usr/local]
-- enable-shared build shared library
In my environment, I also needed the following options:
--disable-asm disable platform-specific assembly optimizations
configure Example
$./configure--prefix=/usr/local--enable-shared--disable-asm
