This structure served as a bridge between data pointers and frames, but it suffers from several limitations: - it is not refcounted and data must be copied to every time - it cannot be expanded without ABI break due to being used on the stack - its functions are just wrappers to imgutils which add a layer of unneeded indirection, and maintenance burden - it allows hacks like embedding uncompressed data in packets - its use is often confusing to our users AVFrame provides a much better API, and, if a full blown frame is not needed, it is just as simple and more straightfoward to use data and linesize arrays directly.
