# 文件名：flvget.sh
# 本脚本利用 http://www.flvurl.cn 或 http://www.flvcd.com 提供的服务解析在线视频并下载
# 受支持的站点列表见 http://www.flvurl.cn 及 http://www.flvcd.com

# 用法：
# flvget.sh <在线视频地址> [清晰度]
# 示例：
#	flvget.sh http://www.iqiyi.com/dongman/20121105/077f6156dad52548.html super
# 清晰度参数是可选的，可用的选项有：normal、high、super、super2
# 如果解析时由于无法连接服务器造成不能解析，可能需要使用代理：
#	[PROXY=<协议>://<主机>:<端口>] flvget.sh <在线视频地址> [清晰度]
# 例如：
# 	PROXY=http://127.0.0.1:8087 flvget.sh http://www.iqiyi.com/dongman/20121105/077f6156dad52548.html super
