[编码选项 编码log]--verbose选项提供更多的选择

[Yang-Xijie]

uavs3e --verbose的说明为：

  -v, --verbose [INTEGER] (optional)
    : verbose level
	 0: no message
	 1: frame-level messages (default)
	 2: all messages

但是个人感觉1和2并没有差异……都包含逐帧的信息（Linux, Ubuntu 18.04.2 LTS, uavs3e version: 1.2.208_release，也可能是操作系统上版本的问题）

参考x265的--log-level说明

--log-level <integer|string>
Controls the level of information displayed on the console. Debug level enables per-frame QP, metric, and bitrate logging. Full level enables hash and weight logging. -1 disables all logging, except certain fatal errors, and can be specified by the string “none”.

0. error
1. warning
2. info (default)
3. debug
4. full

希望编码得到的基本信息为最开头的 视频、参数设置信息 和 最后面的视频编码数据，省略中间逐帧的信息，而不是现在default的 frame-level messages

另外，如果可以，基本信息可以再精简一些，输出的log可以更贴近自然语言一些
