Up to you, my far guess is that you actually unref too much something 
somewhere, and endup doing "use after free" object that holds a mutex 
and crash. Normally, valgrind, with the environment 
G_SLICE=always_malloc gives an overview of that very quickly, and can 
often be done before cutting down you pipeline. I say you, because it's 
an habit to blame the new and shiny code, but obviously it's not 
impossible that libvaapi or the graphic driver is bugged. You have 
already said that without HW acceleration it's fine.
