FLV edit without reencoding

[shorto]

Hello all!

Just wanted to ask if there is a way to edit FLV files or bteter said cut out some video without reencoding it. I'm asking this only cuz of Andy's FLV joiner since if you can join files together without reencoding can you cut them apart as well?

Try AVIDEMUX

Also...
If target container format is not necessarily FLV, You can use VirtualDub with an appropriate input plugin.

I don't see what ffmpeg converting has to do with flv cutting.

But you could use ffmpeg to cut a flv...not that simple from a commad line software though.

OK AVIDemux simply crashes with my file on all computers... any others?

Yea....I have NO idea why anyone would recommend AviDemux for FLV files. I've been using Avidemux for years and have never had any success with FLV files with it.
BUT...FLV files are complete crap. They are the worst to try to do anything with. My only success with them was using something like and OLD version of SUPER and converting them to something else first...then editing.....but SUPER now SUCKS as well. Don't download and install SUPER.....you'll be sorry.

ffmpeg -i videoinput.flv -ss 00:00:00 -t 00:10:00 -vcodec copy -acodec copy videooutput1.flv

cut file start to 0 for 10 minuts
note -vcodec copy -acodec copy is direct stream copy not recompress

in virtualdub used to import flv or other files plugin ffmpeg (FFmpeg supported Files) for virtualdub download here http://code.google.com/p/ffinputdriver/downloads/list
