  "message": "Fix rate overflow in av1_block_yrd()\n\nIn av1_block_yrd() and av1_block_yrd_idtx(), the unscaled coefficient\nrate accumulated across transform blocks can exceed INT_MAX \u003e\u003e 11 on\nlarge partitions in lossless or low-quantizer realtime mode, causing a\nsigned 32-bit integer overflow when shifted left by\n2 + AV1_PROB_COST_SHIFT.\n\nCompute the shifted rate in int64_t and clamp to INT_MAX / 2 in\nav1_block_yrd(), av1_block_yrd_idtx(), and av1_estimate_block_intra().\n\nUnittest added.\n\nBug: 568565869\nChange-Id: I8ef2e6cfcd6efed37f13f5ad7f343effacde9065\n",
