RM视频播放器 [2011-4-20更新异步模式可以融合进 RM 画面] - Project1

#===============================================================================
# ■ [VX]RM VX 视频播放插件
# [VX]RMVXVideo <- 没有空格、下划线
#-------------------------------------------------------------------------------
# 使用说明:
#
# * 请先确定您所使用的视频文件格式, 具体的可以查看文件的扩展名.
#
# * 确认后, 请打开"引用网址", 从中下载文件格式的解码器. 都下载也是可以的,
# 不过这样工程会比较臃肿.
#
# * 解压解码库, 将里面的全部 dll 文件都添加到 VideoData 文件夹下. 注意:
# VideoData 文件夹下只能放置 dll 文件.
#
# * 最后可以使用脚本了. 脚本使用方法如下:
# $scene = Scene_Video.new(file_name, layer, x, y, width, height, type, playing, play_mode)
# 其中:
# file_name(String) : 文件名
# layer(int) : 加载层数
# x, y, width. height(int) : 播放画布范围定义.
# type(int) : 返回类型 0 Scene_Title; 1 Scene_Map
# playing(bool) : 播放开始类型 true 立即播放; false 手动播放
# play_mode(bool) : 播放模式 true 独占模式; false 异步模式
#
# * 独占模式: 视频在播放的时候让 RM 处于暂停状态, 除非视频播放结束, 或者玩家
# 提前按下 B 键后, 场景才会切换回定义的场景. 玩家按下 C 键的话, 视频会暂停,
# 再次按下继续播放
#
# * 异步模式: 视频开始播放后, 立即切换到定义的返回场景. 这样就可以一边播放视
# 频, 一边继续 RM 游戏. 不过注意会掉点FPS. 不过对视频毫无影响. 使用这个模式的
# 话, 需要使用者自己手动切换视频的状态(播放, 暂停什么的), 播放结束后也需要使
# 用者自己释放资源
#
# * 状态方法的使用说明:
# 参见"引用网址"

# - beta By 蕾米莉亚·斯卡雷特 or 铃仙·优昙华院·因幡
# * 基本脚本和 dll 组建
#
# - 1.0.1127 By 蕾米莉亚·斯卡雷特 or 铃仙·优昙华院·因幡
# * 使用新架构来构建
#
# - 2.0.0418 By 蕾米莉亚·斯卡雷特 or 铃仙·优昙华院·因幡
# * 不定期更新一些编码库
# * 新的编码库调用方案，减少对系统环境的依赖
#
# - 3.0.0420 By 蕾米莉亚·斯卡雷特 or 铃仙·优昙华院·因幡
# * 新的窗口使用方案. 可以融合进 RM 里
# * 添加异步模式和独占模式选择.
