[mythtv-users] MythMusic mangling meta-data for existing oggs

[Dave Steinberg]

Hi all,

I've got an existing collection of ogg vorbis files that I would like to
use in mythmusic.  I've been ripping my CDs for quite some time using a
perl script, which just executes cdparanoia and oggenc to do the ripping
and encoding.

Unfortunately, it seems that myth is ignoring or mangling the meta-data.
The worst thing is that the artist's name is being repeated in the title.
The genre, year, and tracknum are also being dropped.

For example, here's the command-line that was used to encode one file
(with input piped directly from cdparanoia):

oggenc -q 4 -o "Alanis Morissette - Mary Jane.ogg" -a "Alanis Morissette" \
  -t "Mary Jane" -N 9 -G "Rock" -d "1995" -l "Jagged Little Pill"

Here's what it looks like when I play it with ogg123:

Audio Device:   OSS audio driver output

Playing: Alanis Morissette - Mary Jane.ogg
Ogg Vorbis stream: 2 channel, 44100 Hz
Title: Mary Jane
Artist: Alanis Morissette
Genre: Rock
Date: 1995
Album: Jagged Little Pill
Track number: 9

Here, all the meta-data looks right.  But, when I import it into myth,
here's what shows up in the musicmetadata table (I've reformatted from a
SELECT response, to fit in 80 columns):

intid: 711
artist: Alanis Morissette
album: Jagged Little Pill
title: Alanis Morissette Mary Jane
genre: Unknown Genre
year: 0
tracknum: 0
length: 280000
filename: Alanis Morissette/Jagged Little Pill/Alanis Morissette - Mary Jane.ogg
rating: 5
lastplay: 20040727170534
playcount: 2

I suspect that what's happening here is that myth is totally ignoring the
meta-data that's in the file, and is instead just using the filename.  The
Filename Format option is set to "ARTIST/ALBUM/TRACK_TITLE", but if I try
to set it to "ARTIST/ALBUM/ARTIST - TRACK_TITLE", I just get the full
pathname as the title.

So, I guess there are two issues:

1. Does myth use a different format for storing meta-data from oggenc?  If
   so, is there any easy way to convert it?  Has anyone else had success
   getting myth to see the meta-data in oggs encoded using oggenc?
2. When myth can't find meta-data in the file, can it properly get the
   title if the filename includes the artist?  Is there something else
   that I should set the Filename Format option to?

I'm using Debian packages of myth, including mythmusic_0.15.1-1.

Many thanks for any insights anyone can provide.

Thanks,
Dave
