Checked into GIT x265 updated snapshot of 17122023, along with modified 0013-Multibit...patch as Andrew provided WITH NEW NAME of x265_3.517122023 because until x265_3.5 is deleted in thirdparty/src, the configure file requires a bigger number so that tar file is used.

Modified patch3 as recommended below for the Multibit patchset.

As Andrea has recommended, I am OK with making multibit automatically the default rather than separate IF CAN FIX THE "syntax error" that I found out is not only in ubuntu 16 but is in what I use as the Fedora baseline build. Partial log below:

cmake version 3.17.4 -- The C compiler identification is GNU 10.3.1 -- The CXX compiler identification is GNU 10.3.1 -- Check for working C compiler: /usr/bin/cc -- Check for working C compiler: /usr/bin/cc - works --
...

/bin/sh: -c: line 0: syntax error near unexpected token `('
/bin/sh: -c: line 0: `cmake version 3.17.4 -- The C compiler identification is GNU 10.3.1 -- The CXX compiler identification is GNU 10.3
...
make[3]: [Makefile:4: all] Error 1 (ignored)
make[3]: Leaving directory '/mnt0/build5/cinelerra-5.1/thirdparty/x265_3.517122023'

Will send full log file to see if Andrew knows what it is.

I guess I should study bash a bit more :) because I think this is error I created unintentionally and ignored so far.

Thanks, and I hope you are not jumping over yourself for doing this for us especially now.

According to weather prognosis we will have like "-20 C" right at 1st January, so I think buying a bit more storable food will be good idea, even if usually 10-15 min walk to food store (separate from dog walks) is not a problem.

Be careful!

Compiling with multibit on Ubuntu 16, results in an Error in the log file, although it seems to work anyway. Errors are:
./libx265_main12.a(api.cpp.o): In function `x265_12bit::x265_api_get_208(int)':

sounds like at least one shared lib was missing from final linking stage,like "-ldl". For me on termux another android-specific files was missed, so I added this file to ffmpeg-specific env. variable before configure in termux.bld and disabled cli x265 encoder (because ffmpeg need just *.a library).

I guess you can change x265 multibit patch3 , last cmake line

+cd ../8bit
+ln -sf ../10bit/libx265.a libx265_main10.a
+ln -sf ../12bit/libx265.a libx265_main12.a
+cmake ../source -DEXTRA_LIB="x265_main10.a;x265_main12.a" -DENABLE_SHARED=OFF -DEXTRA_LINK_FLAGS=-L. -DLINKED_10BIT=ON -DLINKED_12BIT=ON

by adding also DENABLE_CLI=OFF like in previous entry.
