I found a couple of problems

* meta-raspberrypi/conf/machine/include/rpi-default-providers.inc
   Does not currently allow PREFERRED_PROVIDER_jpeg to be overriden

* meta-raspberrypi/recipes-graphics/userland/userland_git.bb
   Does not provide virtual/libgles1 (only virtual/libgles2 and virtual/libgl)
   The 'libva' library used by 'vlc' requires virtual/libgles1 and virtual/libgles2

The first issue is simple to fix:
diff --git a/conf/machine/include/rpi-default-providers.inc b/conf/machine/include/rpi-default-providers.inc
index ee3a3ac..ae9ed70 100644
--- a/conf/machine/include/rpi-default-providers.inc
+++ b/conf/machine/include/rpi-default-providers.inc
@@ -7,4 +7,5 @@ PREFERRED_PROVIDER_virtual/egl ?= "userland"
  PREFERRED_PROVIDER_virtual/libgles2 ?= "userland"
  PREFERRED_PROVIDER_virtual/libgl ?= "mesa-gl"
  PREFERRED_PROVIDER_virtual/mesa ?= "mesa-gl"
-PREFERRED_PROVIDER_jpeg = "jpeg"
+PREFERRED_PROVIDER_jpeg ?= "jpeg"
+PREFERRED_PROVIDER_jpeg-native ?= "jpeg-native"

I don't know a workaround for the second.  Any ideas?
