Here is a 55MB sample file, encoded using MPEG Streamclip and selecting the
Apple Component Video YUV422 codec. The codec is wrapped in an AVI
container.

This is how the first frame (roughly) should look like:

Here, again, an uncut version of the console output, trying to convert the
video. This time, I used a more recent version of FFmpeg.
