Hi All

I'd really like to thank everyone who is working on or contributing to mythburn. It adds much needed functionality and works great.

I have noticed a small buggette. If you set dvddir and tempdir to the same place like I did then your logfile and lock files will be deleted right after the get created by line # 224 of mythtvburn.sh. The simple answer is to create a subdir for the DVD output and then this doesn't happen.

I just wanted to share that in case anyone else is wondering why they don't get a log file.

Cheers
Paul

Glad to hear it works well for you!

I've added a check to the install script so setting temp and dvddir to the same directory is no longer possible.

Thanks, Martin

Hi, guess it's time to make the next batch of mythburn updates available:
- some more changes to install script, notably projectx commandline is configurable; should make it easier for systems that don't have a "projectx" wrapper/executable
- reworked DVD structure for DVDauthor; this should get the correct buttons highlighted in the chapter and main menu and allows recordings with different aspect ratios on the same DVD

As usual, you can download a tarball from http://mabene.icomedias.com/mythburn/mythburn.tar.gz.

Update: DVD generation without chapter menu failed with an error; new version is now online. if you request the above url, you get a redirect to the current version - mythburn_20050827b.tar.gz is the fixed file. If you've got the version wighout "b", please download again. Sorry for the fubar.

You can install the new file over your existing directory; when updating please re-run the install.sh script: there's a couple of new entries in the config file that need to be set up properly.

I'm interested in feeback, especially wrt. the new DVD structure (i.e: do the DVDs play correctly on your standalone player?)

Sorry, One feature I didn't get in yet: transcoding mp2 audio to AC3 for NTSC DVDs. I haven't forgotten the feature request, just didn't get round to it yet.

Thank you Mabene for your effort. I tried your mythburn tarball of August 27 and your projectx binaries. Installing was easy with the instructions provided here. However I run the scripts on a "headless" backend that doesn't run a Xserver. When I try to create a DVD iso image projectx fails as soon as it starts because it cannot output to a Xserver. Leaving this message in the log:



I have encountered a similar situation on a different system with Tomcat where Java needed a X libs to create pictures. That was remedied by adding -Djava.awt.headless=true to the Java command line. I tried it here too, but no avail. Googling shows Xvfb as a workaround (just like the error message suggests), but I wondered if there is a more graceful solution. I suppose someone running a Mythfrontend as user mythtv and Mythburn from the webserver as user www-data may find problems too connecting to the Xserver.

Projectx really wants to connect to an X server, even though it doesn't actually display anything in batch mode. The best workaround is really Xvfb - a virtual X server that is started and killed within the Mythburn scripts. This works just fine on a headless backend.

Thanks for the quick reply. I have installed Xvfb using apt. Now I see that there is a Xvfb process started:



but the Java process still can't output to Xvfb even though it seems aware of it's display number (33):

Any thoughts???

Solved it!

When I tried to run Xvfb interactively as the user www-data, I got these errors:



Googling for it revealed that the sockets needed to be created once as root. Running the same Xvfb command as root fixed it. Now I have succesfully created a first test DVD. Thanks again for your effort and help.

As promised earlier, a new release is available that lets you recode audio to ac3 format if
- video format is ntsc
- there's no ac3 audio stream in the original file
- the option to recode mpeg2 to ac3 is set
- you've got ffmpeg and a decoder for mpeg2 audio (like mpg123 or madplay) installed.

Other changes in this release:
- changed ordering of audio streams for recordings with multiple audio streams. Streams are sorted first by format and next by PID / PES-ID. sort order for format depends on the video format: pal gets first mpeg2 then ac3 streams, ntsc gets ac3 first and mpeg2 next. This should help compatibility issues with older ntsc players.
- added dependancy checks to the install script; installation should now warn you if you're missing any required tools.

same installation procedure as last time: download http://mabene.icomedias.com/mythburn/mythburn.tar.gz, unpack to a directoy of your choice, run install.sh script.

if you're upgrading, unpacking or copying over your existing installation shouldn't hurt anything. please rerun install.sh to initialize new config settings. both ffmpeg and mpg123 (or madplay) are only required if you want to use audio recoding.

Hello,

OK, I've made two coasters. The first was my fault (I guess), I needed to update transcode, and I didn't catch the errors in the log. I don't see what's wrong with the second. The menu comes up, but I can't select any of the videos. I have:

mjpegtools 1.6.2
dvdauthor 0.6.11
imagemagick 6.2.2.3
transcode 0.6.14
projectx 0.82.0.00

I read about the incompatibility of dvdauthour 0.6.11 and imagemagick. but this is on a gentoo system, everything was compiled, and I didn't see the specified errors. What I do see is:

STAT: Processing /myth/mythburn/temp/final_sceneselection1.mpg...
WARN: attempt to update tv format from ntsc to pal; skipping
WARN: Discontinuity in audio channel 8; please remultiplex input.
WARN: Previous sector: 0.178 - 0.178
WARN: Current sector: 0.256 - 0.256
WARN: Discontinuity in audio channel 8; please remultiplex input.

Ignore me...somehow my xine keymap got replaced, so no DVDs were working the way I thought they should. The second DVD I made works great, thanks!

mabene your doing a great job keeping these scripts alive!

Well done!

I'd like to incorp this into KnoppMyth. If someone would install against the latest release and provide me notes, that would be great.

G'day folks,

Sorry to be a bit dopey about this, but I am following the instructions and trying to debug the Mythburn install. When I fire up a DVD burn from MythWeb, it fails. So I run the command from a shell and I get the same results as Willem above, ie errors regarding the Java App unable to connect to the Xvfb Display :33.

I checked that Xvfb was running, and it was.

I read the bit in the WIKI about running the command (Xvfb etc) as root the first time. I did this but still no cigar, when they say run as root do they mean to run it after SU'ing in , or is this some other problem to do with UID or permissions, sorry but I'm not sure where to go from here.
Thanks in advance
Matt

At some point the MythBurn scripts try this command as user www-data:



When the sockets are not in place (/tmp/.X11-unix) you get the error messages like I described above. I fixed it by logging in as root (su - should work just as well) and run the command above and ending it with <CTRL>+<C>. This creates the sockets. Then you can try again as the user www-data. This worked for me.

The only thing I need to look into is why these sockets disappear after some time. There may be a script that cleans out /tmp. Haven't had time to investigate that. Perhaps one of you guys know? I saw these lines in /etc/default/rcS:



They probably have got to do with cleaning out /tmp...

UPDATE:

/etc/init.d/bootmisc.sh cleans out /tmp at boottime. It leaves some files alone. I expanded this list with .X11-unix so it should stay next time. We'll see at the next reboot.

G'day,

I had a look, and the Mythburn scripts are definitely starting Xvfb, but as root ? Maybe this is my problem, maybe I am supplying the wrong answers to install.sh ? I will have to dig deeper.

Thanks for the rapid response by the way

Matt
