使用Yocto建立gstreamer

Question

我正在尝试为IMX53 Evk板构建gstreamer.我从http://freescale.github.io/#download下载了Yocto 并运行以下命令.

#MACHINE=imx53qsb
#source setup-environment build
#bitbake core-image-minimal

它构建了u-boot,内核和文件系统.文件系统没有gstreamer.我也想建立gstreamer.

根据我的理解,现在有两种方法来构建gstreamer.

方法1.修改distro.conf文件以构建gstreamer.我不知道如何在distro.conf中添加gstreamer条目.分布是分布式的.

方法2.使用gstreamer条目添加IMAGE_INSTALL_append.我怀疑的是我们必须在IMAGE_INSTALL_append中添加什么名称.

我可以看到以下与gstreamer相关的bb文件.你可以帮助我在local.conf中的IMAGE_INSTALL_append中添加我必须添加的字符串.

Answer 1

你可以添加

IMAGE_INSTALL_append += "gstreamer"

答案很长,你应该添加通常存储在PN配方变量中的包名.你可以在这里阅读PN变量.包名称也可以使用PACKAGES 变量进行管理.
