    # Platform is being enforced here to solve issues like:
    # issue /usr/bin/ld: skipping incompatible /usr/local/lib/libavdevice.so when searching for -lavdevice
    #
    # The tools to check the compiled objects format showed:
    # objdump -a /opt/srt_lib/lib/libsrt.so (file format elf64-littleaarch64)
    # objdump -a /usr/local/lib/libavformat.so (file format elf64-little)
    #
    # Once the platform was fixed, the problem disappeared. Even though the configured platform
    # is amd64, the final objects are x64, don't know why yet.
