I am making a Cin_20240630 build by myself for the OS UbuntuStudio_16.04_LTS_64bit. I read in the MailingLists thanks to Phyllis and Andrew_R, I need to use specific instruction. My usual steps were: 1) cd to "cinelerra-5.1" directory 2) make clean 3) ./autogen.sh 4) ./configure --with-single-user --without-shuttle-usb \ --without-vaapi --without-vdpau \ --disable-dav1d \ 5) make 2>&1 | tee log 6) grep "\*\*\*.*error" -ai log ( Check for obvious build errors ) 7) make install From What I understand, with Cin_20240630 the steps are: 1) cd to "cinelerra-5.1" directory 2) make clean 3) export FFMPEG_EXTRA_CFG="--disable-decoder=vvc" ( before running autogen.sh / configure / make ) 4) patch -p1 < alt_shortcuts.patch ( to use standard shortcuts ) 5) ./autogen.sh 6) ./configure --with-single-user --without-shuttle-usb \ --without-vaapi --without-vdpau \ --disable-dav1d \ --enable-libaom=no ( "--enable-libaom=no" added, without double quote ) 7) make 2>&1 | tee log 8) grep "\*\*\*.*error" -ai log ( Check for obvious build errors ) 9) make install I am ignorant in Linux, so I would like to understand if the instruction *export FFMPEG_EXTRA_CFG="--disable-decoder=vvc"* write something in somewhere or not. Because my Operating System is UbuntuStudio_16.04, is there a way to build Cinelerra-GG using an old FFMPEG and/or libaom? Could you drive me to make that, if possible (and it has sense) and easy for a simply User like me, please? Thanks! IgorBeg
