I just updated the gstreamer from 1.14. when I was using the gstreamer editing service it gives an error  when setting the mode for the GES. this is in c++.

GES:ERROR:../ges/ges-pipeline.c:1144:ges_pipeline_set_mode: assertion failed: (pipeline->priv->valid_thread == g_thread_self())

I use this to set the mode of rendering or preview.
HANDLE handle = reinterpret_cast<HANDLE>(_beginthreadex(0, 0,&VideoPipeline::ThePreviewModeThread, pipe->pPipeline, 0, 0));
CloseHandle(handle);
