[FLVTool2-users] question about modifying frame rate metadata

  Hi --  I have some FLV files that have an incorrect frame rate.
  The frame rate is 20 but it should be 5.
   
  Is it possible to inject new metadata into the FLV file to correct this?
   
  I.e. I want to make the framerate 4, and perhaps I have to also change the duration of the video from 129.075 to four times that, since the video will get longer.
   
  Is this possible with this tool?
   
  I would try it but there is no example of what syntax to use to overwrite existing metadata,
  and the wiki appears to be down.

  p.s. below is the current metadata
   
  <?xml version="1.0" encoding="UTF-8"?>
  <root>
  <duration>129.075</duration>
  <lasttimestamp>129.075</lasttimestamp>
  <videocodecid>2</videocodecid>
  <audiocodecid>5</audiocodecid>
  <audiodelay>0</audiodelay>
  <canSeekToEnd>false</canSeekToEnd>
  <width>320</width>
  <height>240</height>
  <videodatarate>0</videodatarate>
  <audiodatarate>0</audiodatarate>
  <framerate>20</framerate>
  <creationdate>unknown</creationdate>

  <metadatadate>4/18/2007 1:53:37 PM GMT-0500</metadatadate>
  <videosize>3306104</videosize>
  <audiosize>620993</audiosize>
  <datasize>2111</datasize>
  <filesize>3929221</filesize>
