I got more informations using the lastest version of gst-plugin-gl : 

This is the gstreamer debug output : 

0:00:00.246154721 vaapivideomemory
gstvaapivideomemory.c:167:gst_video_meta_map_vaapi_memory: unsupported map

** (POC_DISPLAY:13123): CRITICAL **: gst_gl_shader_compile: assertion

So, I tried to reproduce the problem without using vaapidecode element, and It
seems to work correctly. Now, I'm not a expert, but this unexcepted behavior
may be cause by the vaapidecode element.
