我这也出现很多的这种消息，硬件解码失败，丢失帧

我在其他网站上找到了一个说法：

硬解码是不会给你合并帧的，丢进去硬件一帧要么解的出来，要么就解不出来。 如果送mpp的一帧不完整，你要开SPLITE_MODE，这样mpp软件部分会去合并，但是建议自己合并完完整帧再送mpp。

但是不知道怎么开启splite_mode，

这个最后的解码报错估计是最后一帧的最后一包不完整导致出错的，没什么问题的。

看 mpi_dec_test 里的 need_split 标志

programcj commented 3 years ago

@HermanChen 已经解决了 mpp可以屏蔽 解码错误信息的功能，不注意看文档确实很难发现 最近github国内太难访问了，什么时候也弄一个比较好的国内的镜像呢？
