           Summary: [pngenc] Remove the buffer == file assumption
           Product: GStreamer
           Version: HEAD CVS
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: Normal
         Component: gst-plugins
        AssignedTo: gstreamer-bugs at lists.sourceforge.net
        ReportedBy: algernon at bonehunter.rulez.org

Right now pngenc assumes that the buffer is preciesly equal to the whole data it
must process. That breaks spectacularly when using something like this:

gst-launch filesrc location=test.raw !
video/x-raw-rgb,depth=(int)32,bpp=(int)32,width=(int)48,height=(int)48 ! pngenc
! filesink location=out.png

In my tests, out.png contained only a part of the input data (the first 1024
bytes encoded into png, which is no suprise).

Attached will be a patch that removes this assumption.
