  "message": "Disable specialcase for last frames if the sequence contains ARFs.\n\nfirstpass.c contains some rate adjustment code that assures that the\nlast few frames in a sequence abide by rate limits. If the second-to-\nlast group of frames contains an alt-ref frame (ARF), the last golden\nframe (GF) is zero bytes, and we will thus spend a ridiculously high\nnumber of bits on regular P-frames trying to hit the target rate. This\ndoes slightly enhance the quality of these last few frames, but has\nno perceptual value (other than hitting the target rate).\n\nDisabling this code means we consistently (slightly) undershoot the\ntarget rate and consequently do worse on the last few frames of a\nclip, which is particularly noticeable for small clips. The quality-\nper-bitrate is generally better, ~0.2% better overall on derf-set,\nespecially on clips such as garden, tennis, foreman at low bitrates.\nHas a negative effect on hallmonitor at high bitrates.\n\nChange-Id: I1d63452fef5fee4a0ad2fb2e9af4c9f2e0d86d23\n",
