# flvtool2(1)

a manipulation tool for flash video files

## NAME

flvtool2 - a manipulation tool for flash video files

## SYNOPSIS

**flvtool2** \[-ACDPUVaciklnoprstvx\]...*\[-key:value\]...*in-path\|stdin*\[out-path\|stdout\]*\

## DESCRIPTION

If out-path is omitted, in-path will be overwritten. In-path can be a single file, or a directory. If in-path is a directory, out-path has to be likewise, or can be omitted. Directory recursion is controlled by the -r switch. You can use stdin and stdout keywords as in- and out-path for piping or redirecting.

Chain commands like that: -UP (updates FLV file than prints out meta data)

## 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

- **-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
