In buildroot[1] zlib and bzip2 are optional components, in my testcase with a minimum of features enabled they are disabled. >> --disable-yasm > > This is ok if you know (exactly) what you are doing, > note that as far as I am concerned the resulting > binaries are unsupported.

Compiling ffmpeg with gcc 4.9.2 works fine, I did not test any other gcc5 release but 5.1.0. If I am reading http://git.videolan.org/?p=ffmpeg.git;a=blob;f=configure;h= 3960b735c103ec3224e3f580aa4a91a5212a2d88;hb=HEAD#l2074 correctly then inline asm is only needed for a mmx-enabled build so disabling it, like in my non-mmx testcase, is ok, right?
