Are you building squeezelite against this specific version too? FFMPEG
changes its api/abi so between versions and could possibly be unstable
at any give date. You may want to fix the download version and build
both the library and squeezelite against that. [I don't include ffmpeg
in my squeezelite builds due to incompatibilities across versions]
