  "message": "Convert input frames to monochrome before encoding\n\nWhen encoding a color input to a monochrome output, convert input frames\nto monochrome frames in the AOM_IMG_FMT_I420 format before passing them\nto aom_codec_encode(). The libaom encoder apparently has some problems\nwith encoding input frames in the AOM_IMG_FMT_I422 format to a\nmonochrome output. Although I could not get to the bottom of those\nproblems, this change allows us to bypass those problems.\n\nDo not upgrade profile 0 to profile 2 when encoding to a monochrome\noutput, even if the input is YUV 4:2:2.\n\nBUG\u003daomedia:2913\n\nChange-Id: I86cc6a5a533092e241ba26b95d65a9cbe5fdd67f\n",
