I see an issue here
mythfrontend[17542]: E CoreContext vaapicontext.cpp:348 (CreateDisplay)
VAAPI: Invalid display
mythfrontend[17542]: E CoreContext videoout_openglvaapi.cpp:167
(CreateVAAPIContext) VidOutGLVAAPI: Failed to create VAAPI context.
mythfrontend[17542]: I CoreContext mythpainter_ogl.cpp:62 (ClearCache)
Clearing OpenGL painter cache.
mythfrontend[17542]: I CoreContext mythrender_opengl2.cpp:896
(DeleteOpenGLResources) OpenGL2: Deleting OpenGL Resources
mythfrontend[17542]: I CoreContext mythrender_opengl.cpp:1211
(DeleteOpenGLResources) OpenGL: Deleting OpenGL Resources
mythfrontend[17542]: E CoreContext videooutbase.cpp:318 (Create)
VideoOutput: Not compiled with any useable video output method.
mythfrontend[17542]: E CoreContext mythplayer.cpp:493 (InitVideo)
Player(1): Couldn't create VideoOutput instance. Exiting..

So it's failing to create a connection to the x display for some
reason, and then bombing out. On the bright side it's not actually
crashing so we don't need a gdb backtrace.

What is your DISPLAY variable set to?

Can you re-run that test with `--verbose playback` please?
