x265：在编码过程中我没有获得每帧的完整统计信息
x265: I don't get full statistics per frame during encoding process
我在 Ubuntu 12.04 服务器上使用 x265。
我正在使用命令 --log-level 4 获取每帧的完整统计信息，因为我只获取每帧的帧速率。
这是输出：

我在 Centos 服务器上也有 x265，使用之前的命令我得到 [debug] POC 编号、QP、位、Y U V PSNR 值、SSIM 和前瞻级别。
这是理想的输出：

正在从 here 读取 x265 1.8，–log-level now controls only console logging, frame level console logging has been removed. 统计信息仅显示在使用 --csv-log-level 2 的 csv 输出文件中。
