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. > Have not tested Debian 9.1 32-bit yet as am getting hung up on cause of > error. >
