ffmpeg has presets for ipod ( which btw also work just as well for Blackberry ) and dvds. Go tweak and select a preset that works for you and go with you. My advise is to use existing ffpresets presets. I think you will find preset in the ffmpeg source/ffpresets Very important : once you get ffmpeg to work just the way you want, back up the source that you used to build your binary and backup all sources of libs . This is important as sometimes refreshing code from repositories breaks the features you depend on . And if you are extremely paranoid like me and your business had a critical dependency on video transcoding, create a Virtual box guest OS, build ffmpeg and tweek till it works and then save that image for emergencies. Its about a Days work in all. I have a shell script that scans my "input folder"(an ftp dir) once it finds a file , it invokes ffmpeg process. On a quad core box, I max my cpu utilization at 8 ~10 concurrent instances of ffmpeg. Your mileage would depend on factors like bitrate etc.
