HM下载

HM不能直接从网页下载，而是采用SVN管理代码的——首先，下载合适版本的TortoiseSVN，这里我们下载的是最新版本1.14.1-64bit：

在这里插入图片描述

下载后双击安装，一直点确定就行。安装完成后在要下载HM的文件夹（此处为D:\HM）右键，选择Repo-browser:

在这里插入图片描述

在弹出的URL框中输入HM的下载地址：https://hevc.hhi.fraunhofer.de/svn/svn_HEVCSoftware/tags/，可以看到不同版本的HM，这里我们选择最新的HM版本，并右键选择checkout，即可进行下载：

在这里插入图片描述

补充说明：后期版本的SCM表示该版本含有SHVC、MV-HEVC和3D-HEVC版本分支。

HM运行

这里使用VS2017打开HM->build文件夹，选择vs2015.sln，此时可在解决方案资源管理器中看到九个项目：

在这里插入图片描述

右击“解决方案’HM_vc2015’(10个项目)”->“生成解决方案”，可以选择debug或者win32模式，与系统是否是64位系统无关：

在这里插入图片描述

生成解决方案成功后，可在项目bin\vc2015\Win32\Debug下面看到TAppDecoder.exe和TAppEncoder.exe两个可执行文件：

在这里插入图片描述

一般我们更关注编码端，即如何将yuv文件转为HEVC文件，这里关注TAppEncoder项目：

在VS2017的解决方案资源管理器中右击TAppEncoder->“设为启动项目”，然后在此右击TAppEncoder->“属性”->“配置属性”->“调试”：

我们只需要修改工作目录，用于放置配置文件，这里按照日期命名，设为..\..\workspace\21_1215，即在HM->workspace下创建一个名为21_1215的空文件夹（自己创建），命令参数此处填入-c encoder_intra_main.cfg -c sintel.cfg，分别为帧内编码的配置文件和一个名为sintel的YUV序列文件的配置文件。

在这里插入图片描述

下面我们在刚才的workspace\21_1215中放置配置文件和视频序列：

encoder_intra_main.cfg可在HM->cfg中找到模板
sintel.cfg`可以在HM->cfg->per-sequence中找到模板
视频序列可以从Index of /hevc/hm-15.0-anchors/bitstreams/i_main/ (bbc.co.uk)中下载.bin格式的265压缩文件，然后在本地转为YUV序列，这里我们采用的是提前准备好的YUV序列：sintel.yuv

下面我们修改encoder_intra_main.cfg：

BitstreamFile 编码后的码流序列文件名，默认为str.bin
ReconFile 编码后重建的YUV文件名，默认为rec.yuv
QP 编码的量化系数，此处设为最大值51

然后修改sintel.cfg：

InputFile：可以写绝对地址，也可以直接写要编码的YUV文件名，但是此时要把文件放在workspace
SourceWidth和SourceHeight：帧宽和帧高
FramesToBeEncoded：要编码的帧的数目，此处设置为5

然后编译运行就可以了，结束后会在workspace下面看到编码后的码流序列str.bin和编码后重建的YUV文件rec.yuv。

后编译运行就可以了，结束后会在workspace下面看到编码后的码流序列str.bin和编码后重建的YUV文件rec.yuv。
