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.
Ok, I didn't know the plugin would throw a warning on that dependency,
we don't want a warning for sure.
What confused me is the comment since it clearly states that
plugins-bad is for imxv4l2videosrc.
True, this could be confusing. This is why I changed the comment ;-)
Here is what I think it should look like:
PACKAGECONFIG_mx6q = "eglvivsink g2d ipu mp3encoder pxp uniaudiocodec
v4l2src vpu"
PACKAGECONFIG_mx6dl = "eglvivsink g2d ipu mp3encoder pxp uniaudiocodec
v4l2src vpu"
PACKAGECONFIG_mx6sx = "eglvivsink g2d mp3encoder pxp uniaudiocodec v4l2src"
PACKAGECONFIG_mx6sl = "g2d mp3encoder pxp uniaudiocodec v4l2src"
PACKAGECONFIG_mx7 = "mp3encoder pxp uniaudiocodec v4l2src"
I've ordered the flags alphabetically, feel free to change it.
Regards,
Gary
Thanks, this helps. (uniaudiodec, not uniaudiocodec, but I'll rename
that in the v2 recipe.)
Also, if anybody can try this on older SoCs such as an imx5, I would
welcome patches, both for the recipe and for gstreamer-imx itself :-)
