Subject: AW: [mythtv-users] Archiving Shows to DVD
Hi Jim,
If you need a willing victim/beta tester, I'd be happy to
work on it with you and give you another box to validate
things on. I'm NTSC but running KnoppMyth R5A16. One of the
reasons I built this machine was to have a software project
to play in and maybe contribute stuff back and this is one
piece that would be a big win in WAF
OK, I've now got a first hack ready to break your system :-)
This version uses projectx for remux and commercial cutting. Cutting is
NOT frame accurate, projectx rounds to the nearest GOP. Avidemux2 (which
was used for cutting previosuly) doesn't round - it just produces broken
output files if your cutpoints aren't on a Keyframe.
Requirements:
- projectx (well, obviously )
- Xvfb or local X server
See http://mysettopbox.tv/phpBB2/viewtopic.php?p=32174#32174 for
details.
Changes implemented:
- support for multiple audio streams. Commerical cut or remux will keep
around all audio streams from the original recording. If you've got
recordings with multiple audio streams (say, german and english streams)
you'll get a DVD that allows you to switch languages. I haven't yet
figured out how to find out which stream has which langauge and get this
info over to the DVD, so the audio streams won't have nice names.
- chapter submenu is optional and configurable via the web interface.
while I like having the chapter marks in my titels I don't like the
chapter submenu.
- blue face / upside down thumbnails configurable via variables at the
top of mythtvburn.sh
- add a title listbox to the burn DVD webpage similar to the listbox
in recorded programs. makes it much easier to pick a couple of
episodes from the same series.
- if commercial cutting is disabled, revert to old behaviour and use
cutpoints as chapter marks
patch can be downloaded at
http://mabene.icomedias.com/mythburn/cut-0.3.diff
diff is against current CVS version of mythburn. Let me know how badly
it breaks your system. I've tried this stuff on a gentoo system with
DVB TS Recordings in PAL Format so your box should be about as different
as it's possible to be.
Bye, Martin
Nice to see someone working on the mythburn scripts again. I've been having
a play with them myself recently. One of the problems with the scripts at
the
moment is they where written for use on knoppmyth and contain several hard
coded references to file paths etc. It would be nice to see some sort of
configuration file where you could set the location of the scripts, where to
create and store temporary files, what the mysql user and password should be
etc. to make them work on any distribution.
I also had a lot of problems with file permissions that need sorting out. It
would also be nice to get the install to be more consistent with how myth
installs things. e.g. install all files in ${PREFIX}/share/mythtv/mythburn.
If anyone is interested I have updated the mythburn-ui - the mythtv style
plugin - to compile and work with current svn.
What is the chance of mythburn becoming an official part of MythTV? I think
that would encourage more people to work on it and improve things.

That's on my todo list as it was pretty high on the whishlist in the
comments I've received so far. That and file permissions. Currently it's
a bit of a mess, logs and configs get written right in the program
directories.
installs things. e.g. install all files in
${PREFIX}/share/mythtv/mythburn.
Since I'm running it on gentoo that's exactly where the files already
are on my system :-)
If anyone is interested I have updated the mythburn-ui - the
mythtv style plugin - to compile and work with current svn.
Now THAT's really great news. I haven't yet tried the UI stuff but the
screenshots I've seen sure look nice. Does the UI still work with the
current mythbtvburn.sh script? Around march the cutlist support was
added to CVS, which changes the commandline for mythtvburn (file1 file2
file3 becomes file1 cut file2 nocut file3 nocut), i.e each file is
followed by the cutflag for that file.
What is the chance of mythburn becoming an official part of
MythTV? I think that would encourage more people to work on it and
improve things.
No Idea. Let's CC mythtv-dev and see if we get any comments :-)

Title: Re: Archiving Shows to DVD Ok, I ran MythTVBurn again tonight on a different recorded show (Tripping the Rift) and it got further but it dies with the error below. Does this ring any bells with anyone? - datestamp=08-08-2005 23:28 Building MPEG2 GOP index files... - datestamp=08-08-2005 23:28 - datestamp=08-08-2005 23:28 /myth/mythburn/mythburn/mythtvburn.sh: line 328: /usr/local/bin/tcdemux: No such file or directory Return value is 127 *** MythTV BurnDVD stopped due to error *** It appears to be actually located in /usr/bin so I made a symbolic link to it in /usr/local/bin but does this indicate that something isn't configured properly?

Re: [mythtv-users] RE: Archiving Shows to DVD
1. Demux/Cut MPEG2 content from MythTV with Java based ProjectX. You can download ProjectX from http://www.doom9.org/DigiTV/projectx.htm . This application not only has the ability to cut the MPEG (only on keyframes) without reencoding, but it appears to have fixed all of the audio sync problems for me. I have yet to tackle real long stuff but my kids two hour shows are fine. 2. Re-multiplex audio/video streams with mplex May i ask why one and two are needed? It seems all you are doing is taking it apart and putting it back together again. (I know geeks like to do that, but I always have a part left over). Seriously though is there a particular reason? perhaps you need to demux in order to cut? Likely because a remux is necessary to burn to DVD. A standard ivtv stream contains only video and audio. Burning to DVD requires blank VOBU packets every so often so dvdauthor can put the necessary info there. Tools such as replex and dvb-mplex are able to do this on the fly, but without those two, the only way has been to strip A and V, and then remux with padding of the VOBU stream (e.g. 'mplex -f8 ...') 3. Create DVD structures with dvdauthor if you get sick of doing that, dvdstyler is good front end, and will make the iso (with a pause to test in xine) as well. Or qdvdauthor. I haven't compared in a few months, but at that type I found qdvdauthor to be less unstable and more functional. (note I didn't say more stable). -Cory -- * * Cory Papenfuss* * Electrical Engineering candidate Ph.D. graduate student * * Virginia Polytechnic Institute and State University * * ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users

[mythtv-users] RE: Archiving Shows to DVD
For archiving to DVD I use my Mac. I just transfer over the .nuv file (which is really MPEG-2), rename it .mpg, MPEGStream to get it into DV format, and use Quicktime Pro to cut out the commercials. I can then use iDVD to make a disc with cool menus, etc. Easy.
