ffmpeg - Frames flip upside-down when using -c:v copy - ffmpeg

Question

I tried to just copy (a period of time of) an AVI-Video into another newly created AVI-file using ffmpeg's copy option.
(On Windows 32-bit)
ffmpeg -i "C:\Temp\zzz\myAvi.avi" -c copy -t 00:00:10 "C:\Temp\zzz\myAviNew.avi"
Why are the pictures flipped upside-down in the resulting file ?
(Also the generated new audio is a little distorted.)
Using the same command again on the newly created file will not flip them back again - the pictures stay upside down.
Why this? Is it a bug?
Console brings the following output:

Answer 1

The issue might come from your input file. The copy does exactly what it says, it copies the bitstream from your input container to an output container. When an issue arise, most of the time it is because some data has not been passed from the input to the output, (such as metadata) since video data can't be modified using copy.
Regarding your specific issue, video files can contain metadata to specify the rotation to which be played to the video player.
To add that information back to the output container, you need to add the following attribute to the ouput.
-metadata:s:v:0 rotate=180
Your initial command should look like :
ffmpeg -i "C:\Temp\zzz\myAvi.avi" -c copy -t 00:00:10 -metadata:s:v:0 rotate=180 "C:\Temp\zzz\myAviNew.avi"
