[FFmpeg-user] Problem with ffmpeg frames

[Stefan Kruse]

Okay,
Here is what I entered on shell:

./ffmpeg -i smk-ebay.avi -ss 00:00:00 -f image2 -vframes 1 test.jpg

And the console output is the follow:

ffmpeg version 1.1.git Copyright (c) 2000-2013 the FFmpeg developers
  built on Apr 18 2013 10:53:59 with gcc 4.4.5 (Gentoo 4.4.5 p1.3,

Input #0, avi, from 'smk-ebay.avi':

200 kb/s, 90k tbn, 25 tbc
Stream mapping:
  Stream #0:0 -> #0:0 (h264 -> mjpeg)
Error while opening encoder for output stream #0:0 - maybe incorrect
parameters such as bit_rate, rate, width or height

Hope this helps. Because an working example I cant give. But maybe this
helps.

Thanks Stefan

Instead of using variables, please post an actual
(working) command line that does not contain variables and please post the
complete, uncut console output (not just one line).
