@PokeMMO ideas?

PokeMMO commented 3 years ago

Try running ./gradlew buildFFmpeg first?

MrStahlfelge commented 3 years ago

Generally, a look at the workflow files helps finding out what to do to build the stuff: https://github.com/libgdx/gdx-video/blob/master/.github/workflows/gradle.yml

roiniti commented 3 years ago

./gradlew buildFFmpeg is working fine until it gets to ARM where i get:

arm-linux-gnueabihf-gcc is unable to create an executable file.
C compiler test failed.

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
ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "config.log" produced by configure as this will help
solve the problem.

I recently added some new build instructions to the README, I hope they help ...

[exec] /usr/bin/ld: /home/roiniti/Escritorio/ffmpg/gdx-video-master/gdx-video-desktop/FFmpeg/build-linux64/libavcodec/libavcodec.a(h264_cabac.o): relocation R_X86_64_PC32 against symbol `ff_h264_cabac_tables' can not be used when making a shared object; recompile with -fPIC

That shouldn't be an issue anymore, this was solved by adding -Wl,-Bsymbolic to the build flags on linux.
