Can you list the libavformat version used by your Fedora F17?

Fail: Could not resolve symbol <avformat_open_input>: not optional, no alternatives.

For some reason your system installed version of libavformat do not contain the avformat_open_input function or we simply failed to auto-detect it.

Please try run objdump -T on your Fedora built libavformat.so and check for avformat_open_input
On my Ubuntu 12.04 system I get:
objdump -T /usr/lib/i386-linux-gnu/libavformat.so.53.21.0 | grep avformat_open_input
000cde80 g    DF .text 000003dc  LIBAVFORMAT_53 avformat_open_input

I think your libavformat got a av_open_input_file function instead of avformat_open_input
objdump -T /usr/lib/i386-linux-gnu/libavformat.so.*| grep av_open_input_file
