Well its very likely I'm afraid.

Below is the output when converting a single frame to jpg on my build environment, this fails when run in Lambda.

The ldd output is, of course this is only valid for the dynamically linked version which also fails on lambda even though the same binaries are available inside the lambda package and the ldd output is similar to the below: 

        linux-vdso.so.1 =>  (0x00007fffe2dde000)
        libm.so.6 => /lib64/libm.so.6 (0x00007ff6d47e1000)

This sounds very unlikely.

Please at least provide the console output your binary produces on your build system and also "ldd ffmpeg"
