mplayer and x264 encodeing

[Wolfpup]

I found x264 Encoding Guide - Linux Encoding after following the instructions there i ended up with the following bash script :

#!/bin/bash
vidfile='/home/wolfpup/Videos/<series folder>/<series ep>.mkv'
mplayer -nosound -benchmark -ass -vo yuv4mpeg:file=>(x264 --demuxer y4m --profile high --level 4.1 --crf 18 --preset veryslow --tune animation --deblock -2:-2 --psy-rd -0.60:0 --qpmin 10 --qpmax 28 --aq-mode 2 --no-mbtree --threads auto --output $vidfile.264 video.y4m 2>&1 | tee $vidfile-x264.log) $vidfile

This script generates the following error :

x264 [error]: could not open input file `video.y4m'

Here is what I eventually want the script to fully do:

1. encode the video adding hardsubs to video
2. encode audio if needed( eg flac/pcm -> aac) ( can be commented out if not needed).
3. extract chapters file from mkv and audio if not encoded in previous step.
4. mux new video, audio, and chapters file into and mp4 container.

Right now I can not get the video to encode so I'm currently stuck.

ANY help will be GREATLY welcomed.
