Bug ID: 745730
Summary: gl: Putting GstGLAllocator as first allocator in
ALLOCATION query
Classification: Platform
Product: GStreamer
Version: git master
OS: Linux
Status: NEW
Severity: critical
Priority: Normal
Component: gst-plugins-bad
Assignee: gstreamer-bugs at lists.freedesktop.org
Reporter: slomo at coaxion.net
QA Contact: gstreamer-bugs at lists.freedesktop.org
GNOME version: ---
Currently GL elements are putting the GstGLAllocator as the first allocator in
the ALLOCATION query. As long as the caps contain the GL caps feature that is
completely ok, but otherwise not.
What can happen otherwise is that the GL allocator is tried to be set on a
GstVideoBufferPool or GstBufferPool, which then completely fails because
GstGLAllocator can't use the normal GstAllocator::alloc() function.
For sysmem caps, only allocators that work normally should be at the first
position.
