Hi Everyone,

I wonder if anyone can shed any light on this subject.

My current setup is as follows;

UK Setup (PAL)
Nvidia GeForce 440MX w TVOUT
Athon 2100+
512 MB Ram
200 GB HDD

Software

KnoppMyth 4.0
Nuvexport
Nuv2disk
Patched MPlayer v1.0pre5 source to support NUV files.

What I would like to do is export NUV files to SVCD using Nuv2disk, which uses mencoder to convert the NUV files to MPEG, rather than running MythTranscode which takes forever even on a 1/2 hour show. I have everything working i.e I can convert the first few minutes of a show but then i get the following error;

Mencoder: Unknown Block Type, possibly NON-MPEG file

Its seems as though the adverts before the start of the show are encoded and then when the show starts the error occurs.

Could this because there are subtitles for the show that I am recording and this information is added to the NUV which then causes the encoder to fail ?
or is it corrupted NUV's ?

I have tried transcoding the files using Myth and then re-encoding using mencoder however this still fail.
Finally, if there is no answer is there a better way to convert recordings into SVCD ?

Any help would be greatly appreciated, I would say that I am fairly new to Linux but I am happy to give things a try.

Thanks

Tim.

I use this and it works great. Nuvexport takes way too long. This is fairly quick.

http://tovid.sourceforge.net/

Also, if your having problems either with this script or nuvexport, try this script out first then run it through one of those programs. Name it ivtv2dvd.sh if you like.

--------------------------------------------------------------------------------------
#!/bin/bash

# ivtv2dvd.sh foo.nuv movie.mpg
# where foo.nuv is your recording and movie.mpg is the output filename.

mpeg2desc -m < $1
mkfifo aud0
mkfifo vid0

mpeg2desc -a0 < $1 > aud0 &
mpeg2desc -v0 < $1 > vid0 &
mplex -f 8 -V -o $2 aud0 vid0
rm aud0 2>/dev/null
rm vid0 2>/dev/null


exit

Thanks for your reply I seem to be having problems with mpeg2desc and mencoder not being able to read the .nuv files.

I am using a BTTV video card and have chosen to use MPEG4 as the output when recording a tv program. Play back runs excellent in Mythtv but as soon as I try to use anything other than mythtranscode I run into problems.

I have followed the instructions you gave (many thanks). However the problems are as follows;

mpeg2desc seems to start working and then says Cannot Read and exits.
If I use the tovid as you suggested I get loads of errors saying unknown hdr.

Any ideas what might going wrong ?

FYI: I can dump the video using mplayer -dumpfile, audio has to be dumped using pcm > wav otherwise I get unknown type, possible NON-MPEG file ...finally i am using Mplayer 1pre5 patched to support NUV. Mplayer site says it now supports NUV is this also for Mythtv NUV ?


Might just buy a DVD writer and be done with it:.

since you are using mpeg4 on software card probably the only thing that will work to do anything with the files is mythstuff or patched mplayer. Oh and I don't know of any other .nuv format in existence, so I am sure this is what the site is referring to.

Ok this is where I have got to.

I downgraded the Mplayer to Knoppmyth version and now mencoder works properly with the NUV files (does anyone have a working 1pre5 patched?, i saw somewhere that seek now fails maybe why i was having problems).

This is my predicament.

I am running a PAL (UK) system.
The NUV stream is encoded to 480x480 mpeg 4.

I would like to archive the videos to SVCD to;

1. Reduce the space used on the HDD. (200GB and already 61% full).
a. Will I actually save much space encoding to SVCD ? as mpeg4 is already compressed.
2. Copy the SVCD files to a CDROM.

Should I just by a DVD Writer and forget the SVCD

P.S Anyone who requies any UK PAL assistance I will be happy to share my knowledge or lack of it as the case may be.
