Try this:

$~: mkfifo /tmp/mplayer.fifo
$~: mplayer -noconfig all -correct-pts -benchmark -nosound -ass -vo
yuv4mpeg:file=/tmp/mplayer.fifo input.mkv & x264 --profile high --preset
slow --tune film --ref 5 --mixed-refs --bframes 3 --b-pyramid strict
--direct auto --filter -1:-1 --trellis 2 --partitions all --8x8dct
--vbv-bufsize 50000 --vbv-maxrate 20000 --me umh --keyint 300
--min-keyint 15 --crf 18 --sar 1:1 --threads 3 --level 4.1 -o output.mp4
$~: mkvmerge -o output.mkv output.mp4 input.mkv -D -S
