The recipe now uses PACKAGECONFIG to allow for enabling/disabling plugins.
Also, mx7 support has been added, and the libfslcodec->imx_codec renaming
has been included.
Changes:
* compositor: Rename ImxCompositor(Pad) to ImxVideoCompositor(Pad)
This prevents conflicts if both the NXP plugins and the gstreamer-imx
are installed in the same rootfs
* Add switches to wscript configuration to enable/disable plugins
Until now, all plugins were built (unless their dependencies were
missing). On some i.MX machines, some features are missing. For
example, the i.MX7 has no VPU. To ensure deterministic builds, it is
useful to selectively disable plugins in the build.
* ipu+pxp: : Fix deadlocks and incorrect logging in case of init error
This was causing a freeze if for example one tries to use PxP elements
on an i.MX6 Dual/Quad
* imxv4l2videosrc fixes and enhancements:
* fixes to interlacing support (incl. workarounds for analog TV input)
* remove format restriction in get_caps function
this removes the limitation on I420 formats
* simplified determination of fps (necessary due to driver limitations)
* eglvivsink: wayland: Do not commit before buffers are swapped
This fixes eglSwapBuffer swaps with damaged frames
* Documentation additions
Adds GPU memory leak notess to the FAQ
* vpu: encoder: Expose motion estimation range as property
* vpu: decoder: Drop output frame if its buffer cannot be allocated

Shouldn't plugins-bad be a dependency for v4l2src only?
The configuration switches only switch on/off the actual plugins (and
their immediate dependencies, like GLES libraries, or libimxvpuapi).
And, gstphotography is a dependency-less component of -bad. In the -bad
tree, gstphotography can be found in gst-libs/ , while stuff that has
external dependencies is in ext/.
What this means is that gstphotography is *not* enabled/disabled by the
v4l2src switch in the build script. This is intentional -
dependency-less GStreamer *libraries* might be used by more than one
gstreamer-imx plugin in the future, which is why they are autoconfigured
in the root build script. (For example, gstreamer-video-1.0 is used by
the vpu plugins as well as the ipu and pxp ones.)
If I put -bad as a v4l2src dependency, then the build script would still
scan for gstphotography if you turn off the v4l2src plugin. bitbake
would then print a warning that -bad is a dependency but is not part of
the DEPENDS list.

Same for the RDEPENDS, I think they should be runtime dependencies of
uniaudiodec and vpu.
True. I will fix this in a v2 recipe.

Wouldn't it be better to split things here for each version of the
mx6, mx6sx doesn't need vpu nor ipu for instance, mx6sl doesn't need
eglvivsink either.

Hm yes, I do not have a full overview over all these variants. If you
have a list handy that I can directly use, it would help, otherwise I'll
get it from the reference manual and the individual SoC specs.
