Move the lavc/imgconvert functions and rename them as follows: avpicture_get_size -> av_image_get_buffer_size() avpicture_fill -> av_image_fill_arrays() avpicture_layout -> av_image_copy_to_buffer() The new functions have an align parameter, which allows to define the linesize alignment assumed in the buffer (which is set or read). The names of the functions are consistent with the lavu/samples API (av_samples_get_buffer_size(), av_samples_fill_arrays()). A redundant check has been dropped from av_image_fill_arrays().
