           Summary: aac encoding: infinitely returning data even if fed
                    0/empty input
           Product: Libav
           Version: 10
          Platform: All
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: libavcodec
        AssignedTo: bugzilla at libav.org
        ReportedBy: thiagossantos at gmail.com


Detected when debugging GStreamer issue
https://bugzilla.gnome.org/show_bug.cgi?id=724536

After gstreamer libav encoder is finished it starts pushing NULL input to the
libav encoder to allow it to flush its remaining data. AAC encoder never
finishes because it keeps returning output for empty input. The output is
empty, too as the pkt.duration is 0.

There are instructions on the gstreamer bug on how to reproduce this issue.
