ffmpeg broken for x264?

After the latest update, unable to encode x264 with ffmpeg.

Name : ffmpeg
Arch : i586
Version : 0.5
Release : 31_git20091120.fc11

Name : libx264_79
Arch : i586
Version : 0.79
Release : 11_20091119.2245.fc11

Message from ffmpeg (using the same command line arguments I was using before):
Error while opening encoder for output stream #0.0 - maybe incorrect
parameters such as bit_rate, rate, width or height

I haven't changed any of these options from before, when it was
working. If I do attempt to correct the parameters, I still get the
same result.

Maybe using -v or -debug to drive up the verbosity/debug level will
show some more insight? There is also a post on this list that
ffmpeg command line parameters have changed again.

Right. Looks like the video presets had changed for x264. Everything
works as usual if I add a
-vpre default

Thanks for your help.

Hi,

Hm, that's what one would expect out of the box. Does that sound like
a bug in ffmpeg? Would you like to report to upstream?

Re: ffmpeg broken for x264? [In reply to]

This is the extra info I got from the ffmpeg output... didn't notice
it before (without the -vpre default):


[libx264 @ 0x831c050]broken ffmpeg default settings detected
[libx264 @ 0x831c050]use an encoding preset (vpre)

I wonder if this is actually a bug in libx264. Shouldn't it use some
default when detecting "broken" default settings?

Maybe I should report upstream to both (ffmpeg and libx264)?

Looks like it's a known bug:
