There is no way to know the texture ID without uploading the frame.<br>
<br>
The texture ID is almost never a constant value. At least, there
will probably be two textures that will be flipped between. At most,
each texture id will be unique.<br>

<div> That is one option if you're looking to use
glimagesink's rendering. If you're rendering the texture
yourself, something like <a
href="https://gitlab.freedesktop.org/gstreamer/gst-plugins-base/-/blob/master/tests/examples/gl/sdl/sdlshare.c"
target="_blank" moz-do-not-send="true">https://gitlab.freedesktop.org/gstreamer/gst-plugins-base/-/blob/master/tests/examples/gl/sdl/sdlshare.c</a>
is more appropriate.<br>

<div>To get the texture id I see a pattern in the cube

<div>What is the current recommended pattern for
rendering to a GL texture which gets consumed by a
shared context? The shared context handles the
rendering.</div>

clutter has not been recommended for many
years. gst-plugins-gl neither for many more.
gst-plugins-gl has been migrated into
gst-plugins-bad as can be seen from the latest
commit on that repo: <a
href="https://github.com/freedesktop/gstreamer-gst-plugins-gl/commit/bedade404ec82432742a901c663f18dfaa24356f"

and then promoted to gst-plugins-base and is
available as the libgstgl-1.0 library.<br>
<br>
