           Summary: gstavvidec: decoded frames lost on EOS
    Classification: Platform
           Product: GStreamer
           Version: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-libav
        AssignedTo: gstreamer-bugs at lists.freedesktop.org
        ReportedBy: aleix at oblong.com
         QAContact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---


When the videodecoder receives an EOS and has already pushed all the frames, it
will call the decoder drain() function and then send EOS downstream.

avviddec has a try loop to get remaining frames. The loop stops when len=0 and
have_data=0;

  if (len < 0 || have_data == 0)
    break;

This causes loss of buffers.
