[FFmpeg-devel] Fw: FFmpeg build failing in IOS 5.1

[Krishna]

Hello,

When I try to link ffmpeg library with IOS application, I am getting following link error.
What may be the issue?

ld: warning: ignoring file ./libavcodec.a, file was built for archive
which is not the architecture being linked (i386)
ld: warning: ignoring file ./libavformat.a, file was built for archive
which is not the architecture being linked (i386)

which is not the architecture being linked (i386)
