Yocto Morty最新的Gstreamer

Question

我想在Yocto Morty中使用最新的Gstreamer，但错误已经发生，无法实现Gstreamer。

我在https://github.com/dv1/meta-gstreamer1.0找到了GStreewer1.12.2配方。因此，我将meta-gStreever1.0目录放在源文件目录中，并添加BBLAYERS +=“${BSPDIR}/+=/meta-gStreer1.0”来构建_fb/bblayers.conf。然后我咬了一下fsl图像-gui，并出现了以下错误。

我发现错误“TypeError: getVar()缺少一个必需的位置参数：‘展开’”在bug.cgi?id=3314的Yocto2.3(Pyro)中得到了修正。此外，Yocto表示，Yocto的gstreamer版本为1.8.3 (参见https://www.yoctoproject.org/downloads/core/morty22更新选项卡)。

这些事情是否意味着我们不能在Yocto中实现GStreamer1.12.2或更高版本？有什么办法吗？如果我们想要实现GStreamer1.12，我们必须使用Yocto还是更高版本？

环境

Yocto (2.2.1) https://github.com/varigit/variscite-bsp-platform/tree/morty#variscite-release-notes

PS：

我重写了getVar和bitbake proceeded.However，我跟踪了error.Would，有人帮我吗？

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:

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.

Answer 1

由于要将较旧版本的Yocto迁移到更新版本，您必须面临约克托的这种变化的后果:展开参数(第二个)为getVar()，getVarFlag()已成为强制性(来自morty的bitbake用户手册)，以前它默认为False。因此，您应该更正这些操作的所有出现，并至少添加False作为第二个参数。
