Bitbake Yocto Morty的最新Gstreamer

我想在Yocto Morty中bitbake最新的Gstreamer，但出现了错误，无法实现Gstreamer

我在上找到了gstreamer 1.12.2配方。 因此，我将meta-gstreamer1.0目录放在sources目录中，并添加BBLAYERS+=“${BSPDIR}/sources/meta-gstreamer1.0”以构建_fb/BBLAYERS.conf。 然后，我对fsl图像gui进行了Bit烘焙，并出现以下错误

摘要：显示了2条错误消息，返回非零退出代码。

我发现Yocto 2.3（Pyro）中的错误“Exception:TypeError:getVar（）缺少1个必需的位置参数：'expand'”已修复。
此外，YP core表示Yocto Morty的gstreamer版本为1.8.3（参见更新选项卡）

这些事情是否意味着我们无法在Yocto Morty中实现gstreamer 1.12.2或更高版本？有什么办法吗？如果我们想实现gstreamer 1.12，是否必须使用Yocto Pyro或更高版本

环境

附言：

我重写了getVar和bitbake。但是我遇到了以下错误。有人能帮我吗

ERROR: gstreamer1.0-plugins-base-1.12.2-r0 do_populate_sysroot: The recipe gstreamer1.0-plugins-base is trying to install files into a shared area when those files already exist. Those files and their manifest location are:

 Matched in b'manifest-imx6ul-var-dart-gstreamer1.0-plugins-bad.populate_sysroot'
Please verify which recipe should provide the above files.
The build has stopped as continuing in this scenario WILL break things, if not now, possibly in the future (we've seen builds fail several months later). If the system knew how to recover from this automatically it would however there are several different scenarios which can result in this and we don't know which one this is. It may be you have switched providers of something like virtual/kernel (e.g. from linux-yocto to linux-yocto-dev), in that case you need to execute the clean task for both recipes and it will resolve this error. It may be you changed DISTRO_FEATURES from systemd to udev or vice versa. Cleaning those recipes should again resolve this error however switching DISTRO_FEATURES on an existing build directory is not supported, you should really clean out tmp and rebuild (reusing sstate should be safe). It could be the overlapping files detected are harmless in which case adding them to SSTATE_DUPWHITELIST may be the correct solution. It could also be your build is including two different conflicting versions of things (e.g. bluez 4 and bluez 5 and the correct solution for that would be to resolve the conflict. If in doubt, please ask on the mailing list, sharing the error and filelist above.
ERROR: gstreamer1.0-plugins-base-1.12.2-r0 do_populate_sysroot: If the above message is too much, the simpler version is you're advised to wipe out tmp and rebuild (reusing sstate is fine). That will likely fix things in most (but not all) cases.
