-passlogfile option is broken (used to work)

[Dominique Dumont]

Hello

I'm using ffmpeg 0.8:

ffmpeg version 0.8, Copyright (c) 2000-2011 the FFmpeg developers

built on Jun 23 2011 08:05:02 with gcc 4.6.1 20110616 (prerelease)

I use -passlogfile option to be able to run several 2-pass ffmpeg in the same directory. I need -passlogfile to prevent log file cloberring. This option did work at some point.

But now, log are always stored in this file:
$ ll passlogfile-0.log
-rw-r--r-- 1 foo bar 3,5M 25 juin 18:29 passlogfile-0.log

Could you fix this option ?

All the best

Please provide command line and complete, uncut output.
If you believe this is a regression, please try to find the version introducing it.

Here's the command line with output:

-passlogfile option works correctly with:
FFmpeg version 0.6.2, Copyright (c) 2000-2010 the FFmpeg developers

built on May 21 2011 16:13:49 with gcc 4.6.1 20110507 (prerelease)

Here's the log file written by ffmpeg 0.6.2:
-rw-r--r-- 1 foo bar 484K 25 juin 19:35 t_vdr_Les_ptites_poules_Dessin_animØ2E_2011-06-23_11_50_5-0_rec-0.log

(Note: I've replaced my login/group by foo and bar)

Hope this helps
