This version of FFmpeg has been compiled without "libx264" enabled.

Your Debian FFmpeg doesn't show "--enable-libx264" in the configuration section.
Your Windows FFmpeg does show "--enable-libx264" in the configuration section.

get_iplayer works OK with Debian because ...
get_iplayer doesn't need libx264.
(get_iplayer only "copies", it doesn't "encode" the video).
