FLVTool2

FLVTool2是用来操作 FLV 的工具

其命令格式：flvtool2.exe [-ACDPUVaciklnoprstvx]... [-key:value]... in-path|stdin [out-path|stdout]

如果out-path未定义，则将覆盖原文件，如果指定in-path为目录，out-path应为同一目录，否则将被忽略。

Commands:
 -A            Adds tags from -t tags-file
 -C            Cuts file using -i inpoint and -o outpoint
 -D            Debugs file (writes a lot to stdout)
 -H            Helpscreen will be shown
 -P            Prints out meta data to stdout
 -U            Updates FLV with an onMetaTag event

Switches:
 -a            Collapse space between cutted regions
 -c            Compatibility mode calculates some onMetaTag values different
 -key:value    Key-value-pair for onMetaData tag (overwrites generated values)
 -i timestamp  Inpoint for cut command in miliseconds
 -k            Keyframe mode slides onCuePoint(navigation) tags added by the
               add command to nearest keyframe position
 -l            Logs FLV stream reading to stream.log in current directory
 -n            Number of tag to debug
 -o timestamp  Outpoint for cut command in miliseconds
 -p            Preserve mode only updates FLVs that have not been processed
               before
 -r            Recursion for directory processing
 -s            Simulation mode never writes FLV data to out-path
 -t path       Tagfile (MetaTags written in XML)
 -v            Verbose mode
 -x            XML mode instead of YAML mode

举个简单的例子,新建文本文件，敲入下列内容，另存为.DAT批处理文件

"C:\Program Files\flvtool2.exe" -UPx "C:\in.flv" "C:\out.flv"

运行该批处理文件，将更新（修复）C:\in.flv文件的Meta Data，同时按照XML格式输出Meta Data信息内容到屏幕。
