A year later I'm now starting to tackle some automation. I have been using 'super' combined with flash video encoder to covert .VOB files to .flv format on my x-Win PC. With my recently upgraded to Ubuntu Linux desktop I now have access to ffmpeg and mencoder to do command line conversions. I'm not much for video, just a dabbler who does what is necessary to get from point A to point B. I could use a little advice with the correct arguments to get some reasonable quality for .flv files that will be displayed at 320x240px dimensions, preferably as conservatively sized (MB) as possible. I found an ffmpeg examples which I cannot get to work at all for .vob to .flv: % ffmpeg -i input.vob -f flv -vcodec flv -b 200k -r 25 -s 296x236 -ab 64 -ar 44100 -ac 2 -acodec mp3 output.flv It errors with: "Unsupported codec for output stream #0.1". For avi to flv or mpg the following work: % ffmpeg -i input.avi avi_to_flv.flv % ffmpeg -i input.avi -target pal-vcd avi_to_mpg.mpg Second part of the question, reasonable middle of the road arguments/values for use with mencoder. Here is what I tried and works but I'm not sure how reasonably optimal it is: % mencoder input.vob -of lavf -ovc lavc -lavcopts vcodec=flv:vbitrate=768 -ofps 25 -oac mp3lame -lameopts abr:br=32 -srate 22050 -vf scale=320:240 -o output.flv Thx.... -- Bob Meetin www.dottedi.biz 303-926-0167 Hook up with me on Twitter, Facebook, LinkedIn, Plaxo Pulse and Bebo or catch my blog at www.dottedi.biz/blog.php Standards - you gotta love em - there are so many to choose from!
