Hello,

try:

flvtool2 -Px /path/to/your/movie.flv

An XML string is returned and you can see what meta data has been  
added to the file.

Ciao,
Norman

Subject: [FLVTool2-users] question about modifying frame rate metadata
Message-ID: <284072.30728.qm@web32915.mail.mud.yahoo.com>

  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.

you should be able to overwrite the metadata values without issue, 
although its unclear how that will impact the playback of the video.

Subject: [FLVTool2-users] flvtool2 memory usage on -P, -U on big files
Message-ID: <200704191828.57704.nickolay.kutovoy@envisionext.com.ua>

Hello to everybody.

	As I readed some discussion from 2006 year there is problem with memory usage 
on big file. Seems that there is no progress in that problem yet. I reached 
same problem ( 700Mb-1Gb flv file is being completely loaded into memory and 
cpu takes 100% for 20-30 mins ) on big flv for -U key and (!) for -P key too 
(why? for -P we need just to output header from file?.. )

	Tool is awesome but miss such important thing - memory / cpu handling on big 
files... I tried to use yamdi - it takes few sec instead of 20 mins to inject 
data to 300Mb file and almost no memory. But yamdi doesn't allow to print 
meta-data to screen - I'm thinking about patching it to output meta-data...

Thanks for any advise.

Best regards,
Kutovoy Nickolay.

Brooks --
     First of all, thanks...
       I was using just flvtool2 -P, I did not realize I needed to do -PU.
   
     However it didn't work!
     When I ran flvtool2 -PU -framerate:5 file.flv
   
     it changed the framerate all right, but flvtool2 calculated other things like keyframe data and the videodatarate tag and added these to the metadata.
   
     I thought I was able to change the videodatarate from 2000.12 to 400 and slow the file down but I can't seem to replicate this success.
     
    question: does flvtool2 always add keyframe data?
    question: anyone have any success with slowing a file down this way?
    question: if it cant be done this way, what can I do to reencode it to slow it down and preserve the audio data too?

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?

Do you mean that it is possible to change de keyframe interval in a FLV
using flvtool2 ?

If so, how ??
