[FFmpeg-user] ffm file layout

[Soho Soho123]

Hi all,

I see the example of ffserver.conf that describes tmp file about feed
# File=/tmp/feed_name.ffm FileMaxSize=5M

Could someone explain the layout of /tmp/feed_name.ffm?
how to map the struct FFMContext to the file?
Because I got the serious problem about header in struct FFMContext that
are corrupt.
ffserver can not find the valid data content of struct FFMContext.
Does someone have idea?
