According to erenz1202 method, I changed soruce file from FXP to LUKE 1.10.8. After that I added lib file [MIUI v1.10.7 Luke1215 Camera 720p fixed] in lib folder. Then video cam 720P is working.
First install under LUKE kernel then after everthing is working, it can change to Doom Kernel.
It is for an information.
