[mythtv-users] nuvexport/mplayer mp3 conversion problem

Hi all,

I used to have a nice simple facility to export  radio programmes
recorded using DVB-T on freeview.  Somewhere along the way this broke.

I use nuvexport to export XVID and other stuff ok, and I can use it to
export video recordings as mp3 too.  But selecting the audio-only
MPEG2-TS files generated from mythtv leaves the nuvexport script
hanging after selecting a show from the recordings list.  A bit of
perl investigation led me to line 354 of Recording.pm which is
complaining that the HEIGHT variable hasn't been filled in yet.  This
apparently gets filled in by this line (310):

my $data = `$program -v -v -v -v -nolirc -nojoystick -vo null -ao null
-frames 1 -identify '$file' 2>/dev/null`;
and this regex match:

Running $program (which is mplayer) on video recordings generates a
fairly short output within about 10 seconds, including those matches.
Running it on audio-only recordings goes on seemingly forever
(currently 9 minutes and counting) and never makes a match to HEIGHT.

Seems to me the problem lies with nuvexport trying to use mplayer to
find non-existing formatting information for the video file.

Has anyone seen this before? I would really love to be able to export
mp3s again - I have 9 months of Gilles Peterson to listen to ;-)
