[MEncoder-users] "New video file has different resolution or colorspace" when concatenating and scaling files

[stattik]

Concatenating multiple files works fine as long as there is no scaling
involved.  When scaling is involved, I get the following error:

[swscaler @ 02518c80]Lanczos scaler, from yuv420p to yuv420p using MMX2
New video file has different resolution or colorspace than the previous one.
FATAL: Cannot initialize video driver.

Both files are from the same camera and so should have all the same
audio/video properties.
I've uploaded the test samples to
ftp://upload.mplayerhq.hu/MPlayer/incoming/Concatenating_and_scaling_error/

Here's the output:
