I'm trying to add subtitles to an AVI file while minimizing loss in video quality. I can adjust the quality by setting the bitrate in mencoder. I would like to know the bitrate of the original file in order to set this correctly. How can I find out the original bitrate?

ffmpeg -i somefile.avi outfile.avi should spit the bitrate to the command line

ffplay will spit out the bitrate too

Why is an output file name needed? –  tony_sid Jan 1 '11 at 4:48
see the edit...ffmpeg is a transcoder ffplay is a player –  hbdgaf Jan 1 '11 at 4:49
and it isn't required to get it to spit out the bitrate it's just a habit –  hbdgaf Jan 1 '11 at 4:51
If I leave out the output file name then it shows the information. If I give an output file name then it starts creating that file. –  tony_sid Jan 1 '11 at 4:52
yeah...it's a does that ctl-c should stop it –  hbdgaf Jan 1 '11 at 4:53
