I think you are confusing it with avcodec_alloc_frame.
Which is basically the reason I'd like to change it since I get
the suspicion a lot of people confuse the two.
Given the signature of
int avpicture_alloc(AVPicture *picture, enum PixelFormat pix_fmt, int width, int height)
it doesn't work at all for that purpose.
