User might pass picParam->log2_tile_columns as 0 for >4K width In this scenario Vp9WriteUncompressHeader may crash in while loop or huze loop due to possible col_data negative value. To avoid this added a boundary check and making picParam->log2_tile_columns same as min_log2_tile_cols. Signed-off-by: sachin kumar <[email protected]>
