[Ffmpeg-devel] [patch] fall back mmap() call for working on no-mmu systems

this patch tweaks libavformat/grab.c so that if the call to
mmap(MAP_SHARED) fails, the code will retry the mmap() call but this
time with MAP_PRIVATE ... this is needed to work on no-mmu linux
systems where mmap(MAP_SHARED) typically is not supported
