Expand description
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
