Alex Mogurenko	e4788ae31b	avcodec/prores_ks: Fix luma quantization if q >= MAX_STORED_Q The problem occurs in slice quant estimation and slice encoding: If the slice quant is larger than MAX_STORED_Q we don't use pre-calculated quant matrices, but generate a new one, but both qmat and qmat_chroma both point to the same table, so the luma table ends up having chroma table values. Add custom_chroma_q the same way as custom_q. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	7 years ago
