Summary: [0.11] Post tags only in sinks, synchronized to the
stream
Classification: Desktop
Product: GStreamer
Version: 0.10.x
OS/Version: Linux
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: gstreamer (core)

GNOME target: ---
GNOME version: ---
In 0.11 elements should never ever post tag messages. Instead they should send
tag events downstream, which then get converted to a message by the sink. This
is the same as is done for EOS now already.
Advantage of this would be, that tags are only seen by the application at the
time where the corresponding media is inside the sinks and not too early.
Changes would be that gst_element_found_tags() would send a tag event to all
srcpads and that gst_element_found_tags_for_pad() only sends the events.
This can't be done for 0.10 because gst_element_found_tags() would only do
something useful after the change if there are srcpads, while nowadays this
doesn't matter (there only needs to be a bus).
