Searching for a tool which can convert my video into a flv, so that uploading a video into youtube does not take more time. ffmpeg command came handy for me.
Command used:
ffmpeg -i mov00326.mpg -ar 22050 -ab 56 -aspect 4:3 -b 200 -r 12 -s 320x240 test.flv
Note: Sound was not working after converting, but its Okay for me as of now.
