There is unbuildable dependency on virtual/egl from gstreamer1.0-plugins-base because:
1) gstreamer1.0-plugins-base depends on virtual/egl because of "egl" PACKAGECONFIG
2) "egl" PACKAGECONFIG is enabled by
meta-raspberrypi/recipes-multimedia/gstreamer/gstreamer1.0-plugins-base_%.bbappend
PACKAGECONFIG_GL_rpi = "egl gles2"
without respecting the "opengl" in DISTRO_FEATURES like the recipe in oe-core does
openembedded-core/meta/recipes-multimedia/gstreamer/gstreamer1.0-plugins-base_1.14.4.bb:
PACKAGECONFIG_GL ?= "${@bb.utils.contains('DISTRO_FEATURES', 'opengl', 'gles2 egl', '', d)}"
3) virtual/egl is provided either by:
- userland (only without vc4graphics in MACHINE_FEATURES):
meta-raspberrypi/recipes-graphics/userland/userland_git.bb:PROVIDES += "${@bb.utils.contains("MACHINE_FEATURES", "vc4graphics", "", "virtual/libgles2 virtual/egl", d)}"
- mesa (selected with vc4graphics in MACHINE_FEATURES)
meta-raspberrypi/conf/machine/include/rpi-default-providers.inc:PREFERRED_PROVIDER_virtual/egl ?= "${@bb.utils.contains("MACHINE_FEATURES", "vc4graphics", "mesa", "userland", d)}"
- vc-graphics(-hardfp)
meta-raspberrypirecipes-graphics/vc-graphics/vc-graphics.inc:PROVIDES = "virtual/libgles2 virtual/egl"
4) vc-graphics(-hardfp) recipe are skipped in default setup, because with vc4graphics being
in MACHINE_FEATURES by default since:
690bdca574
the PREFERRED_PROVIDER_virtual/libgles2 is set to mesa in:
conf/machine/include/rpi-default-providers.inc:PREFERRED_PROVIDER_virtual/libgles2 ?= "${@bb.utils.contains("MACHINE_FEATURES", "vc4graphics", "mesa", "userland", d)}"
resulting in skipping the other virtual/libgles2 providers:
vc-graphics-hardfp PROVIDES virtual/egl but was skipped: PREFERRED_PROVIDER_virtual/libgles2 set to mesa, not vc-graphics-hardfp
vc-graphics PROVIDES virtual/egl but was skipped: PREFERRED_PROVIDER_virtual/libgles2 set to mesa, not vc-graphics
5) mesa is skipped when neither opengl nor vulkan are in DISTRO_FEATURES
6) userland doesn't provide virtual/egl because we have the default vc4graphics
meta-raspberrypi/recipes-graphics/userland/userland_git.bb:PROVIDES += "${@bb.utils.contains("MACHINE_FEATURES", "vc4graphics", "", "virtual/libgles2 virtual/egl", d)}"
and it cannot be built anyway, because with the default vc4graphics it depends on libegl-mesa:
meta-raspberrypi/recipes-graphics/userland/userland_git.bb:RDEPENDS_${PN} += "${@bb.utils.contains("MACHINE_FEATURES", "vc4graphics", "libegl-mesa", "", d)}"
and libegl-mesa is provided only by mesa recipe from oe-core which in turn
requires either "opengl" or "vulkan" to be in DISTRO_FEATURES
This causes a lot of unresolved dependencies in default setup with vc4graphics but without opengl.
- with Yocto 2.6 Thud and older it worked, because vc4graphics wasn't enabled by default before:
690bdca574
To build gstreamer1.0-plugins-base with egl PACKAGECONFIG enabled you have 2 options:
A) Just add "opengl" to DISTRO_FEATURES and use the default vc4graphics with mesa providing virtual/egl
B) Use DISABLE_VC4GRAPHICS added in
96c8459c93
to explicitly disable vc4graphics and use userland to provide virtual/egl

As a result of this change, we update the hash in the bcm2835-bootfiles
recipe as well.

Use the IMAGE_NAME_SUFFIX variable to build the SDIMG name. Some layers,
notably meta-mender, change the IMAGE_NAME_SUFFIX variable to something
other that ".rootfs", causing build failures.
