I am not going to build you a tube site but here are the command lines to encode high quality videos for html progressive playback on the iphone and android.
Code:
/usr/bin/ffmpeg -y -i <input_video> -vf scale='640:trunc(ow/a/2)*2' -acodec libfaac -ab 256k -ac 2 -ar 44100 -vcodec libx264 -f flv -fpre <path_to_presets>/presets/libx264-lossless_slow.ffpreset -crf 22 -threads 0 -f mp4 <output_video>
Code:
/usr/bin/MP4Box -inter 0 <video_file>
