How to pull meta:GstVideoGLTextureUploadMeta buffer in system memory?

[jeyp4]

gst-launch-1.0 -v v4l2src device=/dev/video0 ! image/jpeg,format=I420 !
jpegdec ! vaapih265enc ! vaapidecode !
'video/x-raw(meta:GstVideoGLTextureUploadMeta), format=BGRA' ! fakesink

Above pipeline works fine.

Can I replace fakesink with appsink to extract BGRA buffer data in system
memory?
