Thanks for your help! You are right, I should have tried a bit more myself,
I'm a bit under time pressure and was overwhelmed by the plethora of
options that ffmpeg offers.

The result of the conversion using the options you told me looks good
enough, of course without
knowing the internals of ffmpeg (and my video stream) I don't know, whether
this is the most
"loss-least" conversion method.

I could image, that for this particular conversion, assuming an example
sequence of i1p1p2p3p4...
the conversion could yield i1(p1+p2)(p3+p4), which, give or take rounding
issues, would be virtually lossless.

Just out of curiosity: Is there an ffmpeg option to dump the types of all
frames in a video stream?

Thank you!
