These options look useless, I suggest to remove them, if any of 
them make a difference, please report, it may indicate a bug:
--disable-w32threads --disable-os2threads --disable-yasm 
--disable-vis --disable-altivec --disable-mmx 
--disable-mmxext --disable-sse --disable-sse2 --disable-sse3 
--disable-ssse3 --disable-sse4 --disable-sse42 --disable-avx 
--disable-fma4 --disable-armv5te --disable-armv6 
--disable-armv6t2 --disable-vfp --disable-neon

(Does --enable-pic make a difference?)

I may miss something but this seems to indicate that your 
current driver only supports yuyv rawvideo.
