Trying to use a convoluted for loop with VLC and Parallel or OpenMPI with no success. Help?
I have about 12,000,000 mod files I'm trying to turn into a test of "unlimited cloud storage" by running them all through VLC and blowing them into mp3 files. I can get this to work serially but when trying to use openMPI or Parallel, something in the syntax is tripping it up some. Here is an example of the command I'm using. Open to any help or suggestions.
Code:
for file in `find ./modarchive/modarchive_2007_official_snapshot_addendum1/ -name "*.mod" -type f`; do parallel -j4 --citation NEWFILE=`echo $file | sed 's/modarchive/mp3archive/'`;echo working on $file; vlc -I dummy -f $file --sout "#transcode{acodec=mp3,ab=128}:standard{mux=mp3,dst=$NEWFILE.mp3,acce~ss=file}" vlc://quit 2> /dev/null ; done

qmp3report - report mp3 files and directories
SYNOPSIS
qmp3report [option]... file...
DESCRIPTION
qmp3report reads mp3 files or directories containing mp3 files and gives information about them. qmp3report can output the reports with
plain text or in html format. using the latter format, you can navigate your mp3 directories with a web browser.
OPTIONS -a, --all
report all files, not just files with suffix mp3.
-A, --show-all
implies --show-dirs, --show-files and --summary. show report for files and directories and a summary report.
-d, --dirs
show a report for every directory containing reported files/directories. note that if option --all is not set, only will be reported
those directories containing mp3 files.
-f, --files
show a report for every reportable file (see --all).
-h, --help
show a brief help and exit.
-H, --html
output in html format (default is plain text).
-r, --recursive
scan directories.
-s, --summary
show a summary report.
-S, --split
split report across visited directories. qmp3report leaves in each visited directory a file with the report for that directory,
independently of the output format. the name of the report file is the name of the directory with extension .txt or .html depending
on the selected output format.
-v, --verbose
show more detailed info.
-V, --version
show version and exit.
BUGS
variable bit rate (vbr) streams are detected by reading the initial (5) frames in the stream. if their bit rate field differs, the entire
stream is read to compute the duration time with accuracy (see manual info for qmp3info).
if vbr is not detected, qmp3report reads only the first frame in the stream and calculates the duration supposing that (1) the entire
stream is composed by valid frames and (2) all the frames have the same bit rate. this is a fast way to compute the duration of the stream,
but it is not exact: there's an error of 0.3% aprox.
the htmlize function, which converts file names in a suitable form for html format (ie. replacing spaces with %20), is not bulletproof.
tests have been done only with mpeg version 1 layer iii streams, though it may (or not) work with other versions or layers.
