Summary: GST_BUFFER_FLAG_DELTA_UNIT not set to true/false in
gstrtpvp8depay.c
Classification: Platform
Product: GStreamer
Version: 1.x
OS/Version: All
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: gst-plugins-good
AssignedTo: gstreamer-bugs at lists.freedesktop.org
ReportedBy: Morgan.Lindqvist at ericsson.com

GNOME version: ---
The VP8 RTP payload depack pluging does not set the GST_BUFFER_FLAG_DELTA_UNIT
flag to true or false depending on if the decoded picture is a full intra
picture /keyframe or not.
This is done in for instance gstrtph264depay.c using the following code
-----------------
if (out_keyframe)
GST_BUFFER_FLAG_UNSET (outbuf, GST_BUFFER_FLAG_DELTA_UNIT);
else
GST_BUFFER_FLAG_SET (outbuf, GST_BUFFER_FLAG_DELTA_UNIT);
------------------
In the specification, http://tools.ietf.org/html/rfc6386#section-19.1, it is
described how to detect if this picture is a keyframe or not.
