fvp supports ffmpeg 4~7 runtime libraries without rebuilding. you can remove libffmpeg(lobffmpeg.so, libffmpeg.dylib, ffmpeg-*.dll) in fvp destination dir, and add your own ffmpeg libraries(avcodec, avformat etc.) instead, then your ffmpeg will be used. the prebuilt libffmpeg is a lite version with only frequently used features.

Hello and thanks for your prompt answer.

One question: Where do I get prebuilt libffmpeg files for Android and iOS? Google it and didn't find anything.

Thanks again,

Mauricio

build yourself. I have a build script https://github.com/wang-bin/avbuild

moriciogithub commented 3 months ago

Hello.

I'm so sorry to bother you. I have unable to build it. I have setup a VM with Ubuntu 22.04, install the build-essentials, downloaded your script, ffmpeg source code version 6.1.2. After running it comes with message

C compiler test failed. clang: error: unsupported option '-gcc-toolchain'

Do you have a doc with the correct setup in order to build the lib?

Thanks in advance.
