Thanks for your patch. I looked into this, and the problem is not
related to Linaro toolchains, but a compatibility issue with GStreamer
newer than 1.19.x, which changed this GstAppSinkCallbacks structure. I
identified the upstream fix for this problem, backported it, and added
an explanation.

See the resulting commit at:

Thanks a lot!
