      最近在学习H.265视频编码器IP,参考帧的数量好像会直接影响编码的算力成本,请问目前v2.0的编码器具体参考帧数量有确定的数量吗?在具体的码流中会不会有体现?看到相关文章说“如果解码器不知道编码码流的参考帧的数量,将会以最坏的打算来分配解码内存,总成不必要的资源浪费”,这种观点正确吗?

        @damian 目前仅支持一个参考帧

            @bo 你好,我还有一个点没懂,按理说我们编码第二帧的时候是以第一帧作为参考帧的,但是我发现第二帧的load_ref_Luma和load_ref_chroma并不是load的第一帧的重构帧,而是load TV目录下单独的ref.yuv,为什么呢?

              这个是仿真需求,如果上板子的话可以加上总线访问逻辑,改变每次load的ref地址

                @bo OK,意思就是实际的板子中添加总线逻辑后load_ref其实就是load之前的store_db,请问你们有考虑开放核心ip之外的总线接口的全部代码吗

                  @damian 是的, 我们有加上axi、apb总线的ip核的。开源代码是codec的内核,不包含总线访问逻辑的

                    您好,@bo 先生,您能否分享任何注释或任何数据手册,以了解代码中使用此输入和输出的原因和内容

                    我试图首先理解版本 1 代码,然后我发现了 pre_i(模式决定)

                    请引导我完成这个过程。

                    如果您有任何这些东西,请提供

                    谢谢你,先生

                    Hi sir can you please share any notes or any databook for why and what is this input and output is used in code

                    I am trying to understand the Version 1 code 1st and I struck at pre_i (mode decision)

                    Please guide me through this.

                    if you have any these things please provide it

                    Thank you sir
