Bug ID: 797128
Summary: videoaggregator: Notify drained status of a
videoaggregator pad
Classification: Platform
Product: GStreamer
Version: git master
OS: Linux
Status: NEW
Severity: normal
Priority: Normal
Component: gst-plugins-bad
Assignee: gstreamer-bugs at lists.freedesktop.org
Reporter: pudding8757 at gmail.com
QA Contact: gstreamer-bugs at lists.freedesktop.org
GNOME version: ---
Add GstVideoAggregatorPad::drained property and
GstVideoAggregator::pad-drained signal to help monitoring composing
status. Some complex use cases (such as dynamic add/remove composing
images), application might want to know when a stream is completely
consumed.
The issue is that EOS event cannot respect the consumed
status of a stream, because a buffer followed by the EOS might have
long duration and therefore the buffer will be alive until running time
of the other stream is reached to the buffer's running time.
