下載套件及工具

opencv(此次版本為3.4.0 Source code.zip )
CMake(此次版本為3.10.1)->按此直接下載

Transform360

●事前準備 ( 編譯opencv )

1. 下載opencv解壓縮到想要放置的資料夾
2. 找到第一步放置的opencv路徑，並將其複製
3. 開啟CMake
4. 在 source code 的地方輸入opencv路徑
5. 回到opencv目錄底下新增build資料夾
   
6. 在CMake中 Where to builf the binaries輸入opencv build 資料夾的路徑
7. 按下Configure
8. 成功後會出現以下畫面
   
9. configure完之後Generate生成檔案
   
10. Done

●編譯Transform360

1. 開啟CMake
2. 在 source code 的地方輸入 Transform360 路徑
3. 回到 Transform360 目錄底下新增 build 資料夾
   
4. 在CMake中 Where to builf the binaries輸入 Transform360 build 資料夾的路徑
5. 按下Configure
6. 這時會有錯誤，找到OpenCV_DIR欄位並輸入 opencv build 資料夾的路徑
   
7. 再次按下Configure，此時會顯示Done
8. Configure完成後按下Generate生成檔案
9. 檢查目錄已經有編譯完成的檔案了
   
10. 開啟 Transform360\build\libtransform360.sln 專案
11. Build專案(記得切到Release x64)
    
12. 此時會出現 M_PI 編譯錯誤
13. 在 VideoFrameTransform.cpp 檔的最上面添加以下程式碼：

#define _USE_MATH_DEFINES

14. 再重新Build一次(記得切到Release x64)
15. Done( Transform360.lib 會生成在Release裡)
    

●操作Transform360 README.md 中的步驟5~8

1. 複製Transform360裡的 vf_transform360.c 到FFmpeg裡的libavfilter.
   

2. 修改libavfilter裡的 vf_transform360.c 路徑

從以下：

#include "transform360/VideoFrameTransformHandler.h"
#include "transform360/VideoFrameTransformHelper.h"

改成以下：

#include "Transform360/Library/VideoFrameTransformHandler.h"
#include "Transform360/Library/VideoFrameTransformHelper.h"

3. 在libavfilter裡的 allfilters.c 加入以下程式碼:

REGISTER_FILTER(TRANSFORM360, transform360, vf);

4. 在libavfilter裡的 Makefile 加入以下程式碼:

OBJS-$(CONFIG_TRANSFORM360_FILTER) += vf_transform360.o

5. 複製Transform360資料夾至FFmpeg目錄底下
   
6. Done
