mpv播放器基础使用（鼠标，键盘快捷键）

​ mpv是一个开源的命令行视频播放器，支持跨平台。支持详细的配置文件，和脚本的高级特性。并且占用资源比较小十分轻量级。

    这个是最近的稳定版本的官方文档https://mpv.io/manual/stable/

01.帮助信息

在命令行界面输入mpv -h，就会打印出如下的帮助信息

可以看到基础的选项也比较少。但是如果你使用 --list-options 选项，就会打印出一堆选项，估计大多数是要通过配置文件来配置比较方便。所以暂时只要知道这几个基础选项就够用了。

我的需求也很简单，当做ffplay的升级版来用，而且这个软件功能很强大，其实也可以当做potplayer一样当做一个主用的播放器。

mpv -h
Usage:   mpv [options] [url|path/]filename

Basic options:
 --start=<time>    seek to given (percent, seconds, or hh:mm:ss) position
 --no-audio        do not play sound
 --no-video        do not play video
 --fs              fullscreen playback
 --sub-file=<file> specify subtitle file to use
 --playlist=<file> specify playlist file

 --list-options    list all mpv options
 --h=<string>      print options which contain the given string in their name

02.键盘快捷键

总结一下常用操作：

我下面总结的表格，主要是在win10下测试成功了，部分快捷键在mac下面是不一样的

官方文档贴在下面：

Keyboard Control
LEFT and RIGHT
Seek backward/forward 5 seconds. Shift+arrow does a 1 second exact seek (see --hr-seek).
UP and DOWN
Seek forward/backward 1 minute. Shift+arrow does a 5 second exact seek (see --hr-seek).
Ctrl+LEFT and Ctrl+RIGHT
Seek to the previous/next subtitle. Subject to some restrictions and might not always work; see sub-seek command.
Ctrl+Shift+Left and Ctrl+Shift+Right
Adjust subtitle delay so that the next or previous subtitle is displayed now. This is especially useful to sync subtitles to audio.
[ and ]
Decrease/increase current playback speed by 10%.
{ and }
Halve/double current playback speed.
BACKSPACE
Reset playback speed to normal.
Shift+BACKSPACE
Undo the last seek. This works only if the playlist entry was not changed. Hitting it a second time will go back to the original position. See revert-seek command for details.
Shift+Ctrl+BACKSPACE
Mark the current position. This will then be used by Shift+BACKSPACE as revert position (once you seek back, the marker will be reset). You can use this to seek around in the file and then return to the exact position where you left off.
< and >
Go backward/forward in the playlist.
ENTER
Go forward in the playlist.
p / SPACE
Pause (pressing again unpauses).
.
Step forward. Pressing once will pause, every consecutive press will play one frame and then go into pause mode again.
,
Step backward. Pressing once will pause, every consecutive press will play one frame in reverse and then go into pause mode again.
q
Stop playing and quit.
Q
Like q, but store the current playback position. Playing the same file later will resume at the old playback position if possible.
/ and *
Decrease/increase volume.
9 and 0
Decrease/increase volume.
m
Mute sound.
_
Cycle through the available video tracks.
#
Cycle through the available audio tracks.
f
Toggle fullscreen (see also --fs).
ESC
Exit fullscreen mode.
T
Toggle stay-on-top (see also --ontop).
w and W
Decrease/increase pan-and-scan range. The e key does the same as W currently, but use is discouraged.
o (also P)
Show progression bar, elapsed time and total duration on the OSD.
O
Toggle OSD states between normal and playback time/duration.
v
Toggle subtitle visibility.
j and J
Cycle through the available subtitles.
z and Z
Adjust subtitle delay by +/- 0.1 seconds. The x key does the same as Z currently, but use is discouraged.

Set/clear A-B loop points. See ab-loop command for details.
L
Toggle infinite looping.
Ctrl + and Ctrl -
Adjust audio delay (A/V sync) by +/- 0.1 seconds.
u
Switch between applying no style overrides to SSA/ASS subtitles, and overriding them almost completely with the normal subtitle style. See --sub-ass-override for more info.
V
Toggle subtitle VSFilter aspect compatibility mode. See --sub-ass-vsfilter-aspect-compat for more info.
r and R
Move subtitles up/down. The t key does the same as R currently, but use is discouraged.
s
Take a screenshot.
S
Take a screenshot, without subtitles. (Whether this works depends on VO driver support.)
Ctrl s
Take a screenshot, as the window shows it (with subtitles, OSD, and scaled video).
PGUP and PGDWN
Seek to the beginning of the previous/next chapter. In most cases, "previous" will actually go to the beginning of the current chapter; see --chapter-seek-threshold.

Activate/deactivate deinterlacer.

F9
Show the list of audio and subtitle streams (useful only if a UI window is used, broken on the terminal).
i and I
Show/toggle an overlay displaying statistics about the currently playing file such as codec, framerate, number of dropped frames and so on. See STATS for more information.
del
Cycles visibility between never / auto (mouse-move) / always
`
Show the console. (ESC closes it again. See CONSOLE.)
