Seems like a good idea.

The reason for the pipe version's AVOption structure to be outside of
the if is the IMAGEAUTO_DEMUXER macro, so I guess unless we like
really long #ifs then this is as good as it gets.

Quickly checked and it seems like generally the separation of options
seems correct... but I'm not sure about "ts_from_file" . The filename
variable will probably be full of \0s at the point where stat() is
called, as it's only set to something else under "!s->is_pipe" branch
in the beginning of the function if I'm seeing correctly - thus making
this option effectively unusable under the _pipe demuxers?
