[SOLVED]Youtube and Video Codecs

Question

Hey guys
Ok basically today i went to make a screen recording for a friend. and i got this command line of the internet, youtube itself actually. i do remember the guy on the video saying he converts it later
The recording went fine. better than fine, x11grab is impressive
But when i uploaded the video to youtube, youtube failed to process the video, saying it couldnt read the codec
ffmpeg -f alsa -ac 2 -i pulse -f x11grab -r 30 -s $(xwininfo -root | grep 'geometry' | awk '{print$2;}') -i :0.0 -acodec pcm_s16le -vcodec libx264 -vpre lossless_ultrafast -threads 0 -y output.avi
So im wondering how i'd go about converting the file into a format that youtube will accept
i did try this, it convers the video itself but with no audio
mencoder output.avi -o test.mp4 -oac copy -ovc lavc -lavcopts vcodec=mpeg1video -of mpeg
due to this error
mencoder unknown audio format assuming mp2/3 use -fafmttag
I did try searching the arch forums and google. i couldnt find a solution or whats happening with the audio situation with mencoder

If you want to tweak a few parameters along the way:
ffmpeg -i 'input-file.avi' -r 25 -s 640x368 -aspect 16:9 -b 988k -vcodec libxvid -vtag xvid -metadata title='Metainfo Title' -acodec libmp3lame -ac 2 -ab 128k 'output-file.avi'
or to purely copy video as is and transcode audio:
ffmpeg -i 'input.avi' -sameq -vcodec mpeg4 -acodec libmp3lame -ac 2 -ab 128k 'output-file.avi'
man ffmpeg
