      @jie 我们最新的C model 压缩比 相当于 x265 medium 水平,后期准备优化到比medium更好一点。 开源2.0版压缩率没有过多优化

        @tang 在windows上,使用exe测试了416240、19201088分辨率的,都是可以运行的,但是对于480480、12001200的分辨率(这些文件用H264源码测试是没有问题的),没有报任何错误,就直接返回了,生成的文件都为空。

        参数设置:
        0_1562031426970_parameters.png

        测试结果:
        0_1562031458186_result.png

        想问下,是那里出了问题,还是有那些参数没有设置了?

          @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?

                                    @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
                                            如何纠正
                                            我已附上屏幕截图。.请告诉0_1606368230378_1606129535183-screenshot-from-2020-11-23-16-31-27-resized.jpeg
