>> Hi all,
>> I was wondering where's the -passlogfile option after verion 1.0?  The default 1st pass logfile names are ffmpeg2pass-0.log  and ffmpeg2pass-0.log.mbtree. I  can change this default behavior with  -passlogfile  before version 1.0.  I can't find this option after upgrading ffmpeg to version 1.0. How could I specify the 1st pass logfile names now?
