I tried compiling by putting in ./configure... the option "--enable-opencl" but it is not recognized. I tried exporting opencl between the autogen.sh and ./configure steps...: export FFMPEG_EXTRA_CFG=" --enable-opencl" I have no errors during ./configure but I have a crash in make: "ERROR: opencl not found If you think configure made a mistake, make sure you are using the latest version from Git. If the latest version fails, report the problem to the [email protected] mailing list or IRC #ffmpeg on irc.libera.chat. Include the log file "ffbuild/config.log" produced by configure as this will help solve the problem." I attach the cin5-with.log, if it helps. I redid the compilation always with "export..." but putting in ./configure also "--without-thirdparty" but I have a crash after a few seconds of "make". I also attach the cin5-without.log. https://transfer.sh/CXaksQ/cin5.tar.gz
