【Java】简易视频播放器

【效果图】

【功能】

1、当窗口获取焦点后，按空格暂停/播放

2、原速播放键、暂停/播放键、倍速播放键（最高3倍速，每次递增0.5）

3、进度条可点击选择播放位置

4、时间显示、播放速度显示

【项目与工具】

maven、java8、vlc-3.8.0、log4j-1.2.17

【说明】

没事做着玩一玩，其实也可以用一用，不过vlc会报几个错（好像也不会影响使用），目前暂时还没找到解决方法<-_->。错误比如这个[00000000222fd390] direct3d11 vout display error: SetThumbNailClip failed: 0x800706f4

【后记】

2020.06.09

GitHub中的项目，截止到2020.06.09，简易播放器新增以下功能（共12个commits）：

1、声音控制模块：音量百分比显示、点击音量进度条设置音量、鼠标轮滑滚动设置音量

2、选择文件按钮：支持多选文件（暂未判断文件类型）

3、查看播放文件列表（半透明效果）：列表中文件名支持换行显示

4、播放/暂停按钮文案动态显示

5、升级了log4j版本，1.2.17升级到2.13.3

（最新版本与本文展示的源码版本差距有一丢丢大，嘻嘻(#^.^#)，播放模式也改了，之前是写好路径，运行窗口就播放，最新版本是选择文件后点击播放按钮或按空格才播放）
