Bug ID: 785006
Summary: DirectViv texture upload method is broken
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: thaytan at noraisin.net
QA Contact: gstreamer-bugs at lists.freedesktop.org
CC: dv at pseudoterminal.org
GNOME version: ---
If the DirectVIV texture upload method is available, it adds caps
transformations to the glupload negotiated caps set, but might not be able to
perform them when buffers arrive if the buffers don't contain GstMemory from a
physical memory allocator.
That means that this use case no longer works:
gst-launch-1.0 videotestsrc ! glupload ! glimagesink
glupload will negotiate to transform I420 to RGBA, but fail to do it. Instead,
the raw memory upload will output buffers that contain I420 GstVideoMeta, with
RGBA caps and result in:
Got context from element 'sink': gst.gl.GLDisplay=context,
gst.gl.GLDisplay=(GstGLDisplay)"\(GstGLDisplayX11\)\ gldisplayx11-0";
** (gst-launch-1.0:9095): CRITICAL **: gst_video_frame_map_id: assertion

The DirectVIV method really needs a Caps Feature on the received caps to
confirm that the buffers it will be receiving are going to work.
