F1C200S 开启硬件解码流程记录

太不容易了

跌跌撞撞的，总算是在F1C200S上跑起来了H.264 硬解码。



## 参考链接

本文基本上都是参考论坛中下面的帖子整理的，请按顺序阅读。

https://whycan.com/t_4219.html

   这个页面分享了 cedarx 的驱动。

    https://github.com/aodzip/cedar/

https://whycan.com/t_5398.html

https://whycan.com/t_5824.html

https://whycan.com/t_6139.html



感谢以上作者的贡献。



下面我来分享一下我自己基于 buildroot-tiny200 来实现的硬解码过程中遇到的坑，以及我提供的解决方案。

整体的流程是：

1、修改内核支持 cedarx驱动；(修改成功之后F1C200S系统中会存在 /dev/ion 和 /dev/cedar_dev 设备文件)

2、buildroot中适配gstreamer;

3、openmax中进行解码格式转换修改，将MB32转为YV12;

4、gst-omx注册；

5、gstreamer测试验证。



## 关于 OMX_COLOR_FormatYVU420Planar 未定义的问题

这里我按照 https://whycan.com/t_6139.html 这个帖子，修改了gst-omx的版本到1.16.0 ,但是还不能解决问题。



最终通过在 `./output/host/arm-buildroot-linux-gnueabi/sysroot/usr/include/OMX_IVCommon.h` 添加 `OMX_COLOR_FormatYVU420Planar` 解决问题。



//./output/host/arm-buildroot-linux-gnueabi/sysroot/usr/include/OMX_IVCommon.h

    OMX_COLOR_Format18BitBGR666,
    OMX_COLOR_Format24BitARGB6666,
    OMX_COLOR_Format24BitABGR6666,
    OMX_COLOR_FormatYVU420SemiPlanar,		// 添加
    OMX_COLOR_FormatYVU420Planar,			// 添加
    OMX_COLOR_FormatKhronosExtensions = 0x6F000000, /**< Reserved region for introducing Khronos Standard Extensions */
    OMX_COLOR_FormatVendorStartUnused = 0x7F000000, /**< Reserved region for introducing Vendor Extensions */
    OMX_COLOR_FormatMax = 0x7FFFFFFF
} OMX_COLOR_FORMATTYPE;


## buildroot-tiny200 中找不到配置项gst1-plugins-bayer2rgb-neon

  我按照 https://whycan.com/t_5398.html 这个帖子修改 buildroot 中的配置,始终无法找到 `gst1-plugins-bayer2rgb-neon` 配置项，我准备忽略这个，把所有的步骤操作完成之后尝试验证，后来验证失败了，然后接着退回来研究`gst1-plugins-bayer2rgb-neon`,发现`gst1-plugins-bayer2rgb-neon` 这个在 buildroot-tiny200 的 package 下是存在的，但是要配置 gst1-plugins-bayer2rgb-neon ,需要先开启 `BR2_ARM_CPU_HAS_NEON`，然后我在 F1C200S的配置下找不到`BR2_ARM_CPU_HAS_NEON` 。

后来干脆强制修改 .config文件,手动强制在 buildroot-tiny200 中的 .config 中添加：

BR2_PACKAGE_BAYER2RGB_NEON=y
BR2_PACKAGE_GST1_PLUGINS_BAYER2RGB_NEON=y

这波骚操作直接让 buildroot 编译 `bayer2rgb-neon` 和`gst1-plugins-bayer2rgb-neon`。（这样操作不正规，但是我还是没有找到能够正常配置 gst1-plugins-bayer2rgb-neon 的方法，如果各位有相关移植适配经历，欢迎分享）

我预感到好像能成了。



## 执行 gst-launch-1.0 报错



文件系统制作好之后，重新写入SD卡中，然后记得修改`/etc/xdg/gstomx.conf`,按照 https://whycan.com/t_5398.html 中的方法进行修改,否则的话，运行会报错误：

gst-launch-1.0 filesrc location=BadApple.mp4 ! qtdemux ! h264parse ! omxh264dec ! autovideoconvert ! fbdevsink

## 运行成功

  下面附上运行成功的 log，用作参考。
