Bug ID: 794574
Summary: vaapidecode doesn't create enough surfaces for
glimagesink
Classification: Platform
Product: GStreamer
Version: git master
OS: Linux
Status: NEW
Severity: normal
Priority: Normal
Component: gstreamer-vaapi
Assignee: gstreamer-bugs at lists.freedesktop.org
Reporter: vjaquez at igalia.com
QA Contact: gstreamer-bugs at lists.freedesktop.org
CC: bsreerenj at gmail.com, vjaquez at igalia.com
GNOME version: ---
glimagesink stores internally more buffers than vaapidecode creates, leading to
a deadlock.
The workaround is to add a vaapipostproc in the middle, something that
vaapidecodebin normally does.
A real solution is to increase the number that vaapidecode creates, and verify
that the gl buffer pool requires the exact minimum number of buffers.
