[mythtv] Mythmusic and corrupt FLAC files

For what it's worth, I just ripped a CD to FLAC to see what happened.

I got a folder full of tracks. I ran the following commands:
IFS="
"
for file in $(ls -1 *.flac); do flac -t "$file"; metaflac 
--export-vc-to=- "$file"; done

Everything seems OK (see output below).

One thing worth noting is that I recently linked mythmusic against 
libflac.so.6 as opposed to libflac.so.4 which I had used previously. (I 
use Mandrake 10.1. I had to manually tweak some lines in mythmusic to do 
with #define HAVE_INTTYPES_H but I don't think this is the "right" way 
to do this, probably some Makefile magic is better).

Anyways, everything seems cool. Played the files in mplayer too just to 
make sure, no problem at all (although it didn't print out the metadata 
- although I'm not sure if it should!!! Was using ffflac decoder).

When I tried to fast forward in the tracks mplayer displays:
[flac @ 0x8516f50]FRAME HEADER not here

and once or twice I got:
[flac @ 0x8516f50]unsupported channel assignment 15 (channels=2)
[flac @ 0x8516f50]decode_frame() failed

Not sure if that is a problem with the way the FLACs are written or if 
it's just general behaviour with FLAC decoding??

Oh, my version of mythmusic has my multiartist patch (hense the extra 
metadata displayed), but this *shouldn't* affect the way the FLACs are 
written.

Hope this helps in some way.

Col.
