      @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?

                                reg ctx_spflag[0:3];

                                  @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
