老师您好，想请教您几个问题：
1、你们实验室做的H265标准编码器与HM16.6的客观BD-Rate性能大概是多少呢？
2、预测模式中inter和intra的所有模式都进行PK吗？
3、在做ME的时候搜索范围是全图大小，还是一定范围，范围是多少？
4、整个RDO过程bits估计有参考HM那一套上下文模型进行更新吗？
5、intra prediction 在角度预测的时候参考像素用的是原始的还是重构的？
6、是否有一个RTL code的说明文档可以参考呢？
感谢老师解答。

I tried using h264enc_v2.0 developed by Yibo Sir and it worked perfectly and so is using it

did you solve the problem

Sir,can you please tell which module is to be added for rate control??
I'm currently working on h265enc_v2.0 made by you..
I'm not able to get the ouput because of some errors in simulation.I'm attaching the screenshot of the errors in this.
Please tell how to correct the errors.

先生，您能告诉我们要添加哪个模块进行速率控制吗？
我目前正在研究您制作的h265enc_v2.0。
由于模拟中存在一些错误，因此我无法获得输出。我在此附加了错误的屏幕截图。
请告诉您如何纠正错误。2_1606454113783_3.png 1_1606454113783_2.png 0_1606454113782_1.png

Where is the output hevc file located and what is the input file given??
I checked the code thoroughly but did not find any mention about input or ouput??
PLEASE TELL SIR

艺博先生
输出hevc文件在哪里，输入文件是什么？
我彻底检查了代码，但未发现有关输入或输出的任何内容？？
请告诉先生

The parameter 'bs_byte_cnt' isn't matching between f265 and h265
How can it be corrected
I've attached the screenshot..Please tell

模拟时出现一些错误。

at 00000600, Frame Number = 00, mb_x_first = 00, mb_y_first = 00

# at 00049380, Error!

# (MV_X,MV_Y) should be (0c,0c), however is (04,0d)

# ** Note: $finish    : ./tb_top.v(783)

修改办法: 修改/sim/h265core/tb_top.v

# 将所有的$fopen语句修改一下
$fopen( XXXX ,"r" );    ->    $fopen( XXXX ,"rb" )
