Flusters AV1 score is the same. Maybe we have been lucky when allocating memory until now. That said the test stream have 8 tile columns which is unusual but admitted by AV1 specifications.

Use v4l2_av1_tile_info->tile_cols to know the number of colons in the frame. This made auxiliary buffers meory size computation more accurate.
