           Summary: avi index massaging is slow
           Product: GStreamer
           Version: HEAD CVS
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: Normal
         Component: gst-plugins
        AssignedTo: gstreamer-bugs at lists.sourceforge.net

Load a somewhat large file (e.g. 1:30h) with somewhat large audio chunks
(>0.2second) and watch how gst_avi_demux_massage_index() takes more than
two-and-a-half-minute to complete.

The problem is in de chunk cutting (line 1393-1454), which will cut each single
chunk in pieces, move all subsequent chunks further down and then fill in the
new subchunks. This obviously needs to be done using lists instead of an array.
