Anyone help me with finding the correct command?

 

Try yuvfps, the part of mjpegtools.

 

how to use it? what will be the command to run?

 

ffmpeg -i Aare.avi -f yuv4mpegpipe - | yuvfps -s 50:1 -r 50:1 | ffmpeg -f yuv4mpegpipe -i - -b 28800k -y output.flv

Did you install mjpegtools? (-bash: yuvfps: command not found)
Also possibly you have wrong values at source framerate and target framerate at yuvfps parameters. Please look at http://linux.die.net/man/1/yuvfps

Also look at http://lists.mplayerhq.hu/pipermail/ffmpeg-user/2008-December/018095.html

 

Thanks a lot for you help..but what will be the force command? I have limited rights on the server and can not install new services ..

 

Look here: http://ffmpeg.org/ffmpeg-doc.html

 

oki

execute this command:

ffmpeg -i Chupke_Se.avi -y -r 25 -f flv -vcodec flv -s qvga -ab 192 -f mp3 -an outerfile.flv

Everything is just fine but no sound .. what command will work for sound too

 

You can use Moyea Video4Web Converter. It is free and effective to convert all video to FLV. It works well.

 

Intuitive and eay to use
