[FFmpeg-cvslog] doc: clarify -frames options behavior

[Lou Logan]

ffmpeg | branch: master | Lou Logan <lou at lrcd.com> | Tue Nov  4 10:17:45 2014 -0900| [37425fcb04748cf3177113f1615447bf7b3cb7ba] | committer: Lou Logan

doc: clarify -frames options behavior

Replace "frames to record" with "frames to output". The "to record"
makes it seem like an input option, or that it would capture the frames
instead of outputting them.
