Ubuntu16.04下调试gstreamer+rkisp(一)

在上一个关于luvcview任务中发现许多isp功能未实现,考虑用gstreamer再找到独立rkisp插件进行编写.目前由于相关资料较少,可能没有直接的rkisp插件,好在能在githup上找到Linux-Rockchip相关文件.

根据 <RK_Linux_Camera_Gstreamer 应用开发>

1.搭建gstreamer环境

略.

2.安装使用Gstreamer的插件

安装使用 Gstreamer rkisp element:
首先解压缩基于 Gstreamer 的 rkisp 插件,并根据不同环境进行编译安装。
Firefly 开发板上,请运行以下命令:

$ ./autogen.sh --prefix=/usr/local --enable-gst --enable-rkiq
$make
$ make install

在没有编译环境的开发板上,请先在 PC 端运行以下命令进行交叉编译后,再将编译生成的库安装
到开发板上,这里以 excavator 开发板为例:

$ export PATH=/path/to/cross-compiler:$PATH
$ CC=aarch64-linux-gcc ./autogen.sh --prefix=./out --host=aarch64-linux
--enable-gst --enable-rkiq
$ make
$ make install

目前准备在下述几个包中进行编译,怀着试一试的态度考察是否可行:
把它们就当成rkisp试试…
若需需安装交叉编译工具,rk3399如下:

$ sudo apt-get install gcc-arm-linux-gnueabihf \
gcc-aarch64-linux-gnu device-tree-compiler lzop libncurses5-dev \
libssl1.0.0 libssl-dev

检测交叉编译工具:

$aarch64-linux-gnu-gcc -v
