Great, it plays fine! Thank you.

Orientation is right, neither flipped nor mirrored. But for every frame
there is the message

[mjpeg @ 0x87b2140]Can not flip image with CODEC_FLAG_EMU_EDGE set!

displayed.

I you want to check for yourself: the magnets collapse after the finger
moves upwards at the right edge of the picture. play it slow (like -fps 5)
to see it ;-)
