FYI

http://www.ietf.org/mail-archive/web/rtcweb/current/msg07028.html

Now they used:

  x264 --nal-hrd cbr --vbv-maxrate ${rate} --vbv-bufsize ${rate} \
       --vbv-init 0.8 --bitrate ${rate} --fps ${frame_rate} \
       --profile baseline --no-scenecut --keyint infinite --preset 
veryslow \
       --input-res ${width}x${height} \
       --tune psnr \
       -o ./encoded_clips/h264/${clip_stem}_${rate}kbps.mkv ${filename} \
       2> ./logs/h264/${clip_stem}_${rate}kbps.txt

vs:

  ./bin/vpxenc --lag-in-frames=0 --target-bitrate=${rate} 
--kf-min-dist=3000 \
       --kf-max-dist=3000 --cpu-used=0 --fps=${frame_rate}/1 
--static-thresh=0 \
       --token-parts=1 --drop-frame=0 --end-usage=cbr --min-q=2 --max-q=56 \
       --undershoot-pct=100 --overshoot-pct=15 --buf-sz=1000 \
       --buf-initial-sz=800 --buf-optimal-sz=1000 --max-intra-rate=1200 \
       --resize-allowed=0 --drop-frame=0 --passes=1 --good 
--noise-sensitivity=0 \
       -w ${width} -h ${height} ${filename} --codec=vp8 \
       -o ./encoded_clips/vp8/${clip_stem}_${rate}kbps.webm \
       &>./logs/vp8/${clip_stem}_${rate}kbps.txt


Best regards
