首先准备好Yocto的开发环境，具体可参考 http://w.g77k.com/Yocto_Project
然后要准备好iMX6开发版的内核、模块、Firmware以及头文件。
进入开发环境的目录，用编辑器编辑sources/meta-fsl-demos/recipes-fsl/images/luna-image-gui-dev.bb，写入以下内容
include recipes-sato/images/core-image-sato.bb
IMAGE_FEATURES += "debug-tweaks dbg-pkgs dev-pkgs tools-sdk tools-debug tools-profile tools-testapps"
DISTRO_FEATURES += "pulseaudio"
WEB = "web-webkit"
SOC_EXTRA_IMAGE_FEATURES ?= "tools-testapps"
# Add extra image features
EXTRA_IMAGE_FEATURES += " \
${SOC_EXTRA_IMAGE_FEATURES} \
tools-debug \
tools-profile \
qt4-pkgs \
"
SOC_IMAGE_INSTALL = ""
SOC_IMAGE_INSTALL_mx5 = "glcubes-demo"
IMAGE_INSTALL += " \

export IMAGE_BASENAME = "luna-image-gui-dev"
编辑build/conf/local.conf，修改为以下内容

EXTRA_IMAGE_FEATURES = "debug-tweaks dbg-pkgs dev-pkgs tools-sdk tools-debug"

进入build目录，执行命令bitbake luna-image-gui-dev，运行完成后可在tmp/deploy/images/imx6qsabresd找到luna-image-gui-dev-imx6qsabresd.tar.bz2，将其解压到SD卡上作为rootfs使用，并将之前准备好的内核模块、Firmware以及头文件包解压到对应目录。
因为GStreamer 0.10对MPEGTS的支持不佳，因此我们需要使用GStreamer 1.0，这里使用的是GStreamer 1.2.2，gstreamer-imx需要1.2或以上的版本才能编译。
先从之前编译rootfs完成后的tmp/deploy/rpm/cortexa9hf_vfp_neon下获取以下.rpm文件:
alsa-dev-1.0.27.2-r1.cortexa9hf_vfp_neon.rpm alsa-lib-dev-1.0.27.2-r1.cortexa9hf_vfp_neon.rpm libglib-2.0-utils-2.36.4-r0.cortexa9hf_vfp_neon.rpm libfaad2-2.7-r1.cortexa9hf_vfp_neon.rpm libfaad-dev-2.7-r1.cortexa9hf_vfp_neon.rpm faad2-dev-2.7-r1.cortexa9hf_vfp_neon.rpm faad2-2.7-r1.cortexa9hf_vfp_neon.rpm libmad0-0.15.1b-r3.cortexa9hf_vfp_neon.rpm libmad-dev-0.15.1b-r3.cortexa9hf_vfp_neon.rpm使用rpm -ivh (rpm file)来安装它们(注意要按顺序安装) 下载以下文件
http://gstreamer.freedesktop.org/src/gstreamer/gstreamer-1.2.2.tar.xz http://gstreamer.freedesktop.org/src/gst-plugins-base/gst-plugins-base-1.2.2.tar.xz http://gstreamer.freedesktop.org/src/gst-plugins-good/gst-plugins-good-1.2.2.tar.xz http://gstreamer.freedesktop.org/src/gst-plugins-bad/gst-plugins-bad-1.2.2.tar.xz http://gstreamer.freedesktop.org/src/gst-plugins-ugly/gst-plugins-ugly-1.2.2.tar.xz依次解压它们，并进入其目录，执行以下命令 ./autogen.sh --prefix=/usr --disable-gtk-doc --disable-examples make -j6 make install 如果没有错误就说明正常安装完成了 安装gstreamer-imx (https://github.com/Freescale/gstreamer-imx) git clone https://github.com/Freescale/gstreamer-imx.git (开发板上的系统可能不能正常运行git命令，可从其网站上获取tar.gz包来使用) 使用以下命令来编译 (务必准备好内核头文件) ./waf configure --prefix=/usr --kernel-headers=/usr/src/linux/include ./waf -j6 ./waf install 没有出现错误的话即安装完成 最后可以使用 DISPLAY=:0.0 gst-launch-1.0 playbin uri=udp://225.0.0.1:2001 video-sink=imxeglvivsink 来测试GStreamer是否能正常使用硬件解码工作(需要当前局域网内有视频流服务器)。
