Allocate an image with size w and h and pixel format pix_fmt, and
fill pointers and linesizes accordingly.
The allocated image buffer has to be freed by using
av_freep(&pointers[0]).
@param align the value to use for buffer size alignment
@return the size in bytes required for the image buffer, a negative
error code in case of failure
