[mythtv-users] converting the recorded .nuv-files from mythtv to something else.

[Terje Kvernes]

  hello all.  :-)

  I'm another very happy user of mythtv, but I have one thing that
  keeps nagging me -- I'd like to convert those .nuv (nuppelvideo as
  far as I understand) to xvid or at least something playable with
  mplayer.  for the record, I'm running Gentoo (~x86 / "unstable") and
  I have mythtv 0.12 in perfect yummy working condition.

  now, I've tried the following:

$ transcode -x nuv -i 12_20031107173000_20031107180000.nuv  -y xvid 
transcode v0.6.11 (C) 2001-2003 Thomas Oestreich, 2003 T. Bitterberg
[transcode] auto-probing source 12_20031107173000_20031107180000.nuv (failed)
[transcode] V: import format    | unknown  (V=nuv|A=(null))
[transcode] V: import frame     | 720x576  1.25:1

[transcode] V: video buffer     | 10 @ 720x576

(decoder.c) video codec not supported by import module
[transcode] failed to init import modules
[transcode] critical: plug-in initialization failed

  which is slightly depressing.  I've also installed Nuppelvideo
  0.52a, but even that doesn't want to play the nuv-files with
  nuvplay:

$ nuvplay 12_20031107173000_20031107180000.nuv
nuppelvideo file with w=480 and h=480 and fps=25.000000
frames=44922 realframes=44922 effdsp=32008.46
Segmentation fault

  mythtv of course plays these things just fine.  "file" calls these
  files "data", something that doesn't help much either.  I've also
  tried turning off immediate transcoding in every profile, without
  any apparent success.

  any tips and pointers would be greatly appreciated!
