[x264-devel] Add --input-fmt option to lavf input

[Yasuhiro Ikeda]

x264 | branch: master | Yasuhiro Ikeda <wipple625 at gmail.com> | Thu Jan 20 23:12:01 2011 +0900| [bb4182d8ea123666819d9547a7b5234d4da34a1b] | committer: Jason Garrett-Glaser

Add --input-fmt option to lavf input
Conforms to ffmpeg's `-f` option.
Use this when lavf fails to guess the input format.
