GStreamer | gst-openmax | Ver: HEAD CVS
Summary: gst_pad_push() return value is ignored
Product: GStreamer
Version: HEAD CVS
Platform: Other
OS/Version: Linux
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: gst-openmax
AssignedTo: felipe.contreras at nokia.com
ReportedBy: ext-tommi.myohanen at nokia.com
QAContact: gstreamer-bugs at lists.sourceforge.net
GNOME version: Unspecified
GNOME milestone: Unspecified
In gstomx_base_filter.c there is a separate output_thread that calls
push_buffer() that in turn calls gst_pad_push(). The return value of
gst_pad_push() is not taken, and _chain() function (almost) always returns
GST_FLOW_OK.
Instead, the output_thread should save this GstFlowReturn value and _chain()
should use it as a return value. This way the downstream _push() return value
gets propagated upstream, e.g. when pipeline is set to NULL. Currently the
parser element just keeps on pushing frames to decoder, since chain incorrectly
returns GST_FLOW_OK even the gst_pad_push() has returned GST_FLOW_WRONG_STATE.
