Video creation via ffmpeg

[GoogleCodeExporter]

The wiki indicates that the following command-line will result in a video file, 
however it results 
in an error when using Gource v0.17

From http://code.google.com/p/gource/wiki/Videos:

gource --output-ppm-stream - | ffmpeg -y -b 3000K -r 60 -f image2pipe -vcodec 
ppm -i - 
gource.h264

What steps will reproduce the problem?
1. Run the command-line as described above 

What is the expected output? What do you see instead?

Expected output is a video file.  Instead I'm getting this error message:

What version of the product are you using? On what operating system?

Mac OS X Leopard


Running gource on the project works fine when not attempting to create video 
output.

Looks like an error coming from ffmpeg not Gource?

Since the error seems to be from the x264 codec you could try encoding it in
something else that works on your system, eg change gource.h264 to gource.mpeg 
and
it'll try and encode it as mpeg.
