Bug ID: 786054
Summary: mapping vaapi buffer slow
Classification: Platform
Product: GStreamer
Version: 1.10.4
OS: Linux
Status: NEW
Severity: normal
Priority: Normal
Component: gstreamer-vaapi
Assignee: gstreamer-bugs at lists.freedesktop.org
Reporter: frank.huber at barco.com
QA Contact: gstreamer-bugs at lists.freedesktop.org

GNOME version: ---
If the number of decoded videos increase, the time-span of gst_buffer_map()
increases dramatically.
With 16 h264 full HD videos each mapping needs more than 16 ms.
We map the buffer to copy the video data. The copy itself needs only 1 ms.
We assume the increase of the mapping time is a bug, maybe a concurrency issue.
Maybe inside intel vaapi driver, not the gstreamer code.
