- Does anyone have experience using the QuickTime FlattenMovie function to
- create single fork ("flattened") movie files? I am experiencing a possible
- bug, or at least obscure behavior.
-
- The behavior is this: I flatten ordinary movie file A using a little custom program
- that simply calls FlattenMovie, (producing file B) then FTP B round trip
- (in binary mode) to a Unix machine and back (producing file C). A, B, and C all
- have different names on my disk.
-
- Now I delete file B.
-
- Now Simple Player (and other players) fail trying to play the movie from file C, popping
- up the standard "Looking for movie file B" dialog that Quicktime shows when it can't
- quickly resolve a reference to a data file. Of course, I think that QuickTime should be
- finding the self-same file (C) I told Simple Player to open, but it won't accept that answer,
- it wants file B. If I rename C to B, Simple Player can play it perfectly.
-
- My theory is that somewhere inside the flattened movie file is an alias or other reference
- to the flattened movie file B, which wasn't changed via the FlattenMovie procedure.
- Since FlattenMovie was included in QuickTime exactly to handle the case of moving
- movies to other (non-mac) file systems, this seems like a bug to me, and since I want to
- write a "movie server" that can hand off movies to anyone who asks, without dictating the
- name of the file it gets stored in, this is causing me real grief.
-
- Has anyone else seen this, have ideas about what might cause it, or thoughts on how
- I might debug it? Pointers to public domain code that flattens movies would also be
- appreciated, on the off chance that I am not using FlattenMovie correctly.
-
- Thanks in advance.
