[MPlayer-users] FLV, -ss and -hr-edl-seek

[Ronni Egeriis]

Hi,

 

I'm having some difficulties trimming a FLV file with MEncoder.

 

I've tried two different approaches, with -ss and -endpos:

 

mencoder input.flv -ss 00:10:00 -endpos 00:20:00 -ovc copy -oac copy -o
output.flv

 

With this method I get an error message in the output, and MEncoder
doesn't seem to recognise the input "nan kbit/s":

Writing index...

Writing header...

And with -hr-edl-seek:

 

mencoder input.flv -hr-edl-seek -edl a.edl -ovc copy -oac copy -o
output.flv

 

With this method it seems to success, though the output is the exact
same as the input. No differences, other than a larger output file.
