A question or two for any Ubuntu nuvexport user who might be using Kyle's
script (http://tacomafia.net:8080/blog/2006/mythexport/) to export files.
I downloaded from Kyle's site and had to bash the heck out of the script
just to get it to run I was getting errors and it was just jumping to
"Unable to open file.." It didn't like the if statements below... just
curious if I missed something or if it's just an Ubuntu thing?
*# Proper arguments check
if [[ $# -ne 2 ]]
then
echo "ERROR: Invalid arguments"
echo "USAGE: mythexport [infile] [title]"
exit 1
fi
# If .mpg file exists
if [[ -r "$indir$infile" ]]
then
# The "command"*
The other question I have is that my recording looks terrible after
nuvexport finished it, it's blocky and just looks horrific. It's using xvid
so I should think it would be decent... I'm new to nuvexport so maybe I've
missed something obvious???
*#
# nuvexportrc:
#
# This file contains the configuration for nuvexport, and should be
installed
# as /etc/nuvexportrc. You can also copy this file to ~/.nuvexportrc,
where
# nuvexport will look first, if you wish to create settings local to a
# specific user.
#
# support for nuvexportrc is still new, so expect that more default options
# will be added as time goes on (so you'll know what you can edit). In
the
# meantime, you can poke around in the code for add_arg() calls to see
which
# options are available.
#
#
# Anything placed within the <nuvexport> section will be interpreted
# as a global option. Use this section for options that don't relate
# specifically to any particular exporter.
#
<nuvexport>
#
# Set export_prog to ffmpeg, transcode or mencoder, depending on your
# preference of program for exports. This is equivalent to --ffmpeg,
# --transcode or --mencoder
#
export_prog=ffmpeg
#
# Any other parameters set in this file are equivalent to using the
equivalent
# setting as a commandline option. For boolean options like
--deinterlace
# (--nodeinterlace), use deinterlace=yes (or no, true or false) instead.
# Actual commandline options will override anything in this file.
#
#
# Preferred mode -- if you don't set this, nuvexport will ask you what you
# would like to do. Use --mode or any of the mode symlinks (like
# nuvexport-xvid) to override.
#
mode=xvid
#
# Setting underscores to yes will convert whitespace in filenames to an
# underscore character (which some people seem to prefer)
#
underscores=no
#
# Setting require_cutlist to yes will tell nuvexport to show only those
# recordings that have a cutlist
#
# require_cutlist=no
#
# By default, nuvexport picks what it thinks is a good name for your file
# (doing its best to avoid printing "Untitled" into the filename).
Setting
# name will let you change the output format of the filename generated by
# nuvexport. Even after this formatting, nuvexport will still do some
basic
# replacements to make sure that illegal filename characters (eg.
/\:*?<>|)
# are replaced with a dash (or " with a '). The following format
variables
# are supported:
#
# %f -> full path to the filename
# %c -> the chanid of the show
# %a -> start time in YYYYMMDDHHMMSS format
# %b -> end time in YYYYMMDDHHMMSS format
# %t -> title (show name)
# %s -> subtitle (episode name)
# %h -> hostname where the file resides
# %m -> showtime in human-readable format (see --date below)
# %d -> description
# %% -> a % character
#
filename=%t - %m
#
# By default, nuvexport uses an American-style date to represent showtimes
in
# lists and filenames. Use --date to override that with the format of
your
# choosing. See the UnixDate section `perldoc Date::Manip` for
formatting
# options.
#
date=%m.%d.%y
#
# Nuvexport has the option to crop a percentage of the border of each
recording
# in order to get rid of the unsightly edges of the tv signal. The default
2%
# approximates the overscan of an average TV, but you can alter this from 0
to
# 5% to fit your preferences. Please keep in mind that this amount is
removed
# prior to making any aspect conversions like removing black bars from 4:3
# recordings to make a 16:9 export.
#
crop_pct = 2
#
# Alternatively, you can override the general crop_pct to crop a different
# amount from specific sides of the recording.
#
# crop_top = 2
# crop_right = 2
# crop_bottom = 2
# crop_left = 2
</nuvexport>
#
# The sections below work as above, with each more specific section
overriding
# the more generic.
#
<generic>
#
# Default to export to the current directory
#
path = /shared/.mythtv/out
#
# Use the cutlist (not to be confused with the commercial flag list) when
# exporting.
#
use_cutlist = yes
#
# Tell mythcommflag to generate a cutlist from the commercial flags before
# exporting. Don't forget to enable use_cutlist above, too.
#
gencutlist = yes
#
# Contrary to popular belief, enabling multipass will not make your
recordings
# look better. What it will do, however is guarantee that the bitrate
you
# choose will be the average bitrate of your entire encode (meaning that
your
# exports will end up being about the same size per-minute), and that you
# will receive the best overall quality for a files of the same size.
#
multipass = no
#
# Disabling noise reduction can speed up your exports dramatically, but at
the
# expense of some quality. You can also access this on the commandline
via
# the --denoise (or --nodenoise) flag.
#
noise_reduction = no
#
# Deinterlace the video so that it looks better on software players.
#
deinterlace = yes
#
# Crop about 2% from the border of the recording before encoding. This is
done
# to get rid of part of the broadcast signal that is usually obscured by
the
# tv's overscan.
#
crop = yes
#
# You can create settings for each export module type. These are the
# second-most generic sections, and will only be reached if there are no
# matches in the full or generic module names.
#
# If you have a particularly dirty signal, you might want to try to disable
# fast_denoise (it's actually part of yuvdenoise, which both the ffmpeg
# and transcode exporters call). It can be almost twice as slow as the
# default "fast" normal noise reduction, but it considerably more
effective.
# The latest version of yuvdenoise (which is called directly by the
ffmpeg
# exporters) does not support this option, so it is ignored in that case.
#
fast_denoise = yes
#
# If nuvexport is having trouble detecting the *input* aspect ratio of your
# recordings (MythTV used to hard-code all software-encoded files as 1:1
# regardless of the true aspect), set this option to one of the
following:
#
# force_aspect = [ 1:1 4:3 16:9 2.21:1 ]
</generic>
<ffmpeg>
#
# ffmpeg is almost twice as fast if you disable noise reduction
#
noise_reduction = no
#
# By default, nuvexport's ffmpeg module lets ffmpeg handle deinterlacing.
# I've found that this provides the best results, but if you wish to let
# yuvdenoise do it instead, set deint_in_yuvdenoise to a true value.
#
# deint_in_yuvdenoise = no
#
</ffmpeg>
<transcode>
#
# Mythtranscode will always be used for nupplevideo recordings because
# transcode can't read them, but setting force_mythtranscode to yes will
# force nuvexport to call mythtranscode when using the transcode exporter
for
# mpeg recordings, too. This may help problems that some people have
been
# having with transcode not recognizing certain dvb recordings, as well
as
# transcode not working properly on certain ivtv recordings.
#
force_mythtranscode = yes
#
# Setting both force_mythtranscode and mythtranscode_cutlist to yes will
tell
# nuvexport to use mythtranscode's built-in cutlist functions, rather
than
# having transcode use its own. I've found that the cutlists for a
handful
# of ivtv recordings that do not work properly with transcode's internal
# cutlist handler.
#
mythtranscode_cutlist = yes
</transcode>
<mencoder>
</mencoder>
#
# You can also create settings for generic export module names. These will
# only be overridden by full module names.
#
<XviD>
vbr = yes # Enable vbr to get the multipass/quantisation
options
# (enabling multipass or quantisation automatically
enables vbr)
multipass = no # You get either multipass or quantisation;
multipass will override
quantisation = 4 # 4 through 6 is probably right... 1..31 are
allowed (lower is better quality)
a_bitrate = 256 # Audio bitrate of 128 kbps
v_bitrate = 960 # Remember, quantisation overrides video bitrate
width = 624 # Height adjusts automatically to width, according
to aspect ratio
height = auto
</XviD>
#
# Default mp3 bitrate in MythTV is 128
#
<MP3>
bitrate = 256
</MP3>
#
# If you want to provide settings for a very specific export module, you
can
# use its full name, and it will override any more generic settings.
#
#
# The MP4 encoder for ffmpeg has a couple of options unique to itself
#
<ffmpeg::MP4>
# Codec to use (mpeg4 or h264). Please note that h264 support requires the
# SVN version of ffmpeg (not CVS!). In fact, even the mpeg4 codec works
# better with the SVN version.
mp4_codec = mpeg4
# Framerate to use: auto, 25, 23.97, 29.97. PAL will always be 25 fps, and
# auto will set 29.97 for everything over 320x288 and 23.97 for the rest.
mp4_fps = auto
</ffmpeg::MP4>
#
# As does the PSP exporter
#
<ffmpeg::PSP>
# PSP framerate (high=29.97, low=14.985)
psp_fps = low
# PSP resolution (320x240, 368x208 or 400x192)
psp_resolution = 320x240
# PSP video bitrate (high=768, low=384)
psp_bitrate = high
# Create a thumbnail to go with the PSP video export?
psp_thumbnail = yes
</ffmpeg::PSP>
#
# You can also add flags to the one and only mencoder option
#
<mencoder::XviD>
multipass = no
</mencoder::XviD>
#
# You can also make specific profiles called with the --profile parameter
that
# will override other config options (but not commandline arguments).
#
# For example, you could make a profile that would encode your favorite show
# with your favorite settings.
#
<profile::sample>
title = test
export_prog = transcode
mode = xvid
confirm = true
</profile::sample>

The last question I have is related to Myth's User Job's - I had setup in
Post Recording to run nuvexport but it didn't seem to kick off after the
recording finished. Where is the log associated with Post Recording that I
can track down the error or is Post Recording not the correct place to run
the nuvexport job?
Thanks.
AJM,
