Anyway, I rebuild gstreamer-plugin-base as well as gtreamer-plugin-good with<br>
kernel header of 4.19.* in the system. Now it was compiled with dma-buf.h<br>
included and the following message is gone:<br>
gstdmabuf.c:93:gst_dmabuf_mem_unmap:<dmabufallocator2> Using DMABuf without<br>
synchronization. <br>

Anyway, the following warning is still present:<br>
