我正在使用yocto处理IMX6，我正在尝试使用GSTREAMER插件：GDKPIXBUFOVERLAY在我的板上，但我有以下错误：
gst-launch-1.0 autovideosrc ! gdkpixbufoverlay location=image.png ! autovideosink
(gst-launch-1.0:441): GdkPixbuf-WARNING **: Cannot open pixbuf loader module file '/usr/lib/gdk-pixbuf-2.0/2.10.0/loaders.cache': No such file or directory
This likely means that your installation is broken.
Try running the command
gdk-pixbuf-query-loaders > /usr/lib/gdk-pixbuf-2.0/2.10.0/loaders.cache
to make things work again for the time being.
Setting pipeline to PAUSED ...
ERROR: Pipeline doesn't want to pause.
ERROR: from element /GstPipeline:pipeline0/GstGdkPixbufOverlay:gdkpixbufoverlay0: Could not load overlay image.
Additional debug info:

Setting pipeline to NULL ...

所以我尝试运行建议的命令，但我也没有工作。我看了输出：
/usr/lib/gdk-pixbuf-2.0/gdk-pixbuf-query-loaders
# GdkPixbuf Image Loader Modules file
# Automatically generated file, do not edit
# Created by gdk-pixbuf-query-loaders from gdk-pixbuf-2.32.3
#
# LoaderDir = /usr/lib/gdk-pixbuf-2.0/2.10.0/loaders
#
，输出充满了评论。我认为董事会上有什么问题，但找不到哪里。
我是否需要其他一些软件包才能使GDKPIXBUF起作用？我在Krogoth和Pyro分支上对Poky Distribution进行了测试，结果是相同的。
添加到您的配方（ image-your_recipe_name.bb file）必要的软件包和子包装名称为行。在我的情况下，包装分开了，因此，为了使用PNG和JPEG图像叠加层，我的食谱看起来如下：
...
gdk-pixbuf
gdk-pixbuf-loader-png
gdk-pixbuf-loader-jpeg
...
保存更改后，请不要忘记将其击倒：
bitbake image-YOUR_RECIPE_NAME
