Setup the data pointers and linesizes based on the specified image parameters and the provided array.

The fields of the given image are filled in by using the src address which points to the image data buffer. Depending on the specified pixel format, one or multiple image data pointers and line sizes will be set. If a planar format is specified, several pointers will be set pointing to the different picture planes and the line sizes of the different planes will be stored in the lines_sizes array. Call with src == NULL to get the required size for the src buffer.

To allocate the buffer and fill in the dst_data and dst_linesize in one call, use av_image_alloc().

@param dst_data data pointers to be filled in @param dst_linesize linesizes for the image in dst_data to be filled in @param src buffer which will contain or contains the actual image data, can be NULL @param pix_fmt the pixel format of the image @param width the width of the image in pixels @param height the height of the image in pixels @param align the value used in src for linesize alignment @return the size in bytes required for src, a negative error code in case of failure
