UpdateTexture slow

[saxofon]

Hi,

I'm running raylib and gstreamer, trying to get overlays on video.
Works brilliant on my x86 linux laptop and a raspberry pi4 but for some reason rendering the video frame slow on a AMD/Xilinx UltraScale+ ZynqMP SoC shown below here :

In the loop I've measured up the calls which essentially is about all in the loop (some overlay drawing of course but
that is little) :

Jan 19 09:24:19 overlayd[869]: gst_app_sink_try_pull_sample 15 us
Jan 19 09:24:19 overlayd[869]: gst_sample_get_buffer 0 us
Jan 19 09:24:19 overlayd[869]: gst_buffer_map 2 us
Jan 19 09:24:19 overlayd[869]: UpdateTexture 20952 us
Jan 19 09:24:19 overlayd[869]: DrawTextureEx 6 us

Currently running raylib configured as desktop platform and system runs wayland/weston in all three cases.
Perhaps this is due to Mali-400 OpenGL setup?
Loop is similar to https://github.com/saxofon/video-testing/blob/9459bf093abbf422525ec564b928398c33e10711/src/v4l2-gstreamer-raylib.c#L284
Is there a more efficient way perhaps to do video frames with overlays?
