G'day folks,

I have been trying to get to the bottom of why I couldn't get this working, part of this was that www-data wasn't in the mythtv group, and DVD and temp weren't being chowned to www-data:www-data by the install script.

I tested the script ( I'm not god's gift to unix but I had a go) and I think the mkdir's need a waitfor or something similar before the chown that follows. On my system the directories never get chowned as a result of the script, yet echo'ing the variables seems to produce the desired results. Sorry if this sounds a little vague, but like I say , this isn't my strong suit.

My problem is that now mplex seems to fail, but that is a separate issue.

Hi all,

Has anybody had experiences of mis-aligned cuts with projectX? I've used mythtv to cut the programme, but the cuts on the final DVD produced are delayed by varying amounts (5-15 seconds). When I use projectX directly to create the cutfile with the option '(0) use BytePos for cuts', and use the mythburn script it works fine. I don't believe this is just skipping to a GOP boundary - here's why:

What follows is a table of the time the scene ends, and when the cut gets executed:

mythtv -
end of scene = 11min22sec
cuts at = 11min22sec

DVD -
end of scene = 11min17sec
cuts at = 11min28sec

Anybody experienced the same thing? Whats an average length of time between GOP boundaries? I'm wondering whether projectX is finding bad chunks of video, cutting it out, and this is affecting the time.

I would just disable commercial cutting, but this means that some of my video that starts as 16:9 in the adverts (which then changes to 4:3 in the programme) gets encoded as 16:9 throughout - so I'd need to chop the start off.

Agghhh! Please help!

Thanks in advance

Solved!

For those of you who are also confused by this:

ProjectX cuts adverts perfectly, exactly when they start. If you create your cutlist manually and run mythburn you will find that the cuts are slightly off, but this isn't down to being rounded to the nearest GOP.

Instead, enable 'All' commercial detection methods, and load the detected cutpoints when editing a show. If you play it you will find that it is off by about 5-15 seconds and cuts bits off. However! If you ignore this fact and let mythburn do its stuff, projectx cuts perfectly.

A bug in mythtv, mplayer, or unichrome - I'm unsure. I just wanted to enlighten others that were as confused as I was.

Cheers

Hello all,

I'm trying to use mythburn with Mythtv on Fedora Core 3. I have the proper java installed and projectx compiled successfully. Mythburn setup was successful and seems to be functioning perfectly up until you execute "Create DVD". At that point it begins processing but fails when calling projectx with the following: "Re-multiplexing file /video/recordings/1037_20050928205900_20050928220000.nuv
/usr/share/mythburn/scripts/remplex.sh: line 85: /usr/bin/ProjectX.jar: Permission denied". I cant see anything wrong with the permissions of the ProjectX.jar itself. The only thing I've come up with so far is that FC3 runs apache with the user and group apache. Anyone have any ideas??

Thanks!

What are the permissions bits and owners set to on the .jar file? Do these match with the user account that is running the remplex.sh code? I have not looked into MythBurn for quite a while now, so this is just your basic square 1 step.

Hi all,

Tried for some days to get things going but I'll be too stupid ;-(

Downloaded latest mythburn, projectx, javasdk jdk1.5.0_01, created ProjectX.jar, ran install.sh which added 'Burn DVD' to Myth Web just fine

Running it causes troubles though.
Warning at /data/mythburn/mythwebburn/mythtvburndvd_createdvd.php, line 114:
fopen(mythburnconf/mythtvburnconfig.xml): failed to open stream: Permission denied

I googled this:
patching file mythwebburn/mythtvburnconfig.xml Hunk #1 FAILED at 1. 1 out of 1

which tells me that the xml-file should be in the mythburn tarbal, but it isn't for me. In the meantime I got it from CVS but it didn't resolve the problem.
-----
Running from the shell doesn't work either

I get a .m2v and a mp2 file but then I get:
Error Running project X, no log file created. giving up.
There are 3 warnings but harmless I think. They are:
!> missing syncword @ 11744, @ 00:00:00.000
!> found syncword @ 12336
-> src_audio: MPEG-1, Layer2, 48000Hz, stereo, 256kbps, noCRC @ 00:00:00.000
!> 12 frame(s) (288ms) added @ 00:02:00.192

I can't figure out what is going wrong. Any hints greatly appreciated.

The permissions of my ProjectX.jar are: -rw-rw-rw- 1 apache apache 579216 Oct 2 18:16 /usr/bin/ProjectX.jar. I also ran the install.sh as user apache, but unfortunately still get the same results. I get the same from the command line.
thanks again,
aikonis

I think the problem is, that you don't have the permission to write to mythburnconfig.xml.
As mentioned in the warning
You have to do a chown or chmod to the mythburn/conf directory. Perhaps you entered a false user in the install script. I had the same problem a few days ago.

Now Mythburn works fine if I copy the command to the commandline and execute it. The command e.g. "nice /myth/mythburn/mythtvburn.sh 'pal' 'Zwielicht.png' 'Zwielicht.mp2' 'yes' 'no' 'no' 'none.png' 'yes' 'no' 'no' '1011_20050927201000_20050927225500.nuv' 'cut' > /myth/mythburn/temp/mythburn.log 2>&1 &"
doesn't start autmatically. I don't know why, but it doesn't matter, anyway.
But I have a much bigger problem. I record the movies with my PVR 350 make my cutlist, create a new background image + music. All fine, mythburn creates a perfect DVD. But sometimes it happens, that the sound stops playback.
The logfile also shows that the audiofile is much shorter than the moviefile.

Any idea how to solve this bug?

On a knoppmyth box this fixed it for me...

All.

Following on from the excellent work mabene has been doing, I've uploaded the scripts into CVS and also produced a release to help save mabenes bandwidth!

It may take a few hours for the CVS to replicate on sourceforge so be patient!

For the release go here http://prdownloads.sourceforge.net/mythburn/mythburn-oct2005.tar.gz?download

I tried mythburn_20050906.tar.gz used latest from
sourceforge mythburn-oct2005.tar.gz and used 2 versions of ProjectX 0.8.17
and latest 0.90.1.00 with 2 versions of java but still no go.

Reading the install.sh

># Create DVD and temp folders
>mkdir -p $tempdir
>chown ${webuser}:${webgroup} $tempdir

>rm -dfr $dvddir
>mkdir -p $dvddir
>chown ${webuser}:${webgroup} $dvddir># Set folder permissions so the www-group can access them
>chown -R root:root $myfolder

as far as I understand all files and directories will be owned by root, and
therefore I get 'permission denied' messages.

To solve this and all other permission items I made them rw to everyone, just to get going for the moment. This solves the permission problems.

If cutting is chosen, things break immediately with the following:

As far as I understand it stumbles over the first line in temp/cutlist_x.txt

When I disable cutting, I end up with 1 video and 2 audio-streams

I don't understand what the next should be, from the script I believe it
should build MPEG2 GOP index files, but I have no idea why or what causes it
to stumble.

Can somebody 'put the light on' so that even I can see ?

PS. I # all 2> in the scripts, but don't see what is going wrong

Which version of Projectx are you using? I suppose you use 0.9.x. Then you have to open the GUI and change some settings. First you have to select "use frames as cutpoints". The second setting you have to change is the name of your audio output file. The ending of the file has to be mpa not mp2.
You also have to change the name xyz_X.log to xyz_log.txt in all of your scripts.
The commandline of PX also changed. Open mpeg2cut-px.sh and replace the line:
nice -n 19 ${projectx} -o . -p cutlist_x.txt $file
with:
nice -n 19 ${projectx} -out . -cut cutlist_x.txt $file
Alternative you can install version 0.82 of PX, then you don't have to make all these changes.

Thanks for your reaction.
Made the changes in the gui to change to use frames as cutpoints and convert mpa and mpv., but according to the scripts these should be mp2 and m2v. Despite that I tried and there is no difference, the script stops at the same points as before.
Also changed your suggestion of mpeg2cut-px.sh but also to no avail.

I also tried 0.81-9 I think of PX but also no succes.

I'm getting mad !!!!!

Hi again,
your commandline is wrong it's not -ct its -cut.
And do you know that you have to patch version 0.9.1? Sorry, forgot to mention it.
http://forum.dvbtechnics.info/showthread.php?t=2068
It's in german but there is a link to common.zip. Use it to patch the source of PX.
I think thats the reason why PX doesn't find the input file.
I'm pretty sure that my scripts need a mpa file, but perhaps I have an old version, downloaded it a few days ago.
