      @yfor debug之后发现是熵编码里面的dump_buf设置不够大,一般情况下是足够的,dump_buf是用来导出测试TV的。但是特殊情况下,输出码流比较大,超出dump_buf的大小,无法正常导出文件,所以会出现这个问题。PS:与编码过程无关

          @tang 您好,不知道我的理解是否正确,如果f265软件生成的rec.yuv被认为是正确的,作为check文件,那么这个软件是怎么得到的,HM?

                @Fudh 暂不开源,抱歉我不能提供。如果只是确认rec.yuv是否正确,直接和.hevc解码得到的YUV对比即可。谢谢

                    Hello.
                    I always get a "segmentation fault" warning when trying to run the command "./f265 -c f265_encode.cfg" and no data is generated from my .yuv.

                    Anyone knows what could be the reason to that issue?
                    I am using sudo and all the files have the necessary permissions.

                    Thanks.

                              请问cabac_bina.v中的两处for循环,都以i作为循环变量,是不是有问题?

                              reg ctx_spflag[0:3];
                              integer i;

                              begin

                              begin
                              case(ctx[i])

                                @tang 您是否使用Xilinx板(尤其是Zynq ultrascale + zcu102板)成功实现了代码?

                                        I'm getting some errors while doing the simulaion.
                                        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。
                                        f265和h265之间的参数'bs_byte_cnt'不匹配

                                            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 output 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。
