            Bug ID: 792644
           Summary: aacparse mishandles very small raw frames
    Classification: Platform
           Product: GStreamer
           Version: 1.12.4
                OS: All
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: gst-plugins-good
          Assignee: gstreamer-bugs at lists.freedesktop.org
          Reporter: jan.steffens at gmail.com
        QA Contact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

Raw AAC streams we encounter (in RTMP and FLV) occasionally have very
small frames (6 bytes: 27 00 03 20 64 1c). These are smaller than
aacparse's default min_frame_size (ADTS_MAX_SIZE = 10).

When passthrough is disabled or aacparse has to output ADTS, BaseParse
will concatenate these short frames to the following frame before
handling them to aacparse, which processes each input buffer as a single
frame, producing bad output.


Patches follow.
