Re: [dvd::rip] dvdrip fails ffmpeg/h264 2nd pass, wrong log filename

Hiho,

@transcode-users: sorry for the cross-posting, but this issue is in fact
a transcode problem, which was discussed some time ago on 
transcode-users (see archive link below), and I like to refresh this 
thread resp. want to ask if there are any new pointers regarding this 
issue.

Yes, it should if transcode would support 2-pass h264 encoding. I just 
reproduced the problem on my system and found this transcode-users 
posting on this topic:

  http://article.gmane.org/gmane.comp.video.transcode.user/17307/

So it's not only a wrong log filename, but a file with 0 byte size as 
well. So renaming it to x264_2pass.log may make ffmpeg happy (in terms 
of it doesn't complaing about the missing file), but I can't imagine 
that you get a proper h264 2pass encoding from that... ;)

So the only thing I can do for now is switching off 2-pass encoding for
h264 to make it "officially supported" ;) Single pass transcoding indeed
just works as expected.
