Comment (by andrewrk):

 > Your code looks as if you had issues with avcodec_find_encoder_by_name()
 though: Which issues did you see?

 I'm sorry, I don't remember.

 > Why should this codec be overwritten if this is neither the documented
 behaviour of av_guess_codec() nor the behaviour since this function

 I think what you said about this function being very old is reasonable. I
 would be satisfied with a resolution of updating the documentation for
 av_guess_codec to make it more clear what the role of the function is.
