mythburn-0.19 that works with Mythtv-0.19

[drescherjm]

Please read the first 4 posts in this thread as some of the details have been changed as a result of the update..

[EDIT]The source of the jpegyuv segfault has been found. See http://bugs.gentoo.org/show_bug.cgi?id=114103[/EDIT]

There have been few requests (on the mythtv forums and other sites) for a version of mythburn that works with the latest version of mythtv since the current download on the sorceforge does not work. The link for this download is http://sourceforge.net/project/showfile ... e_id=36185.

On my system I have managed to get mythburn working by debugging and patching the code but this became very cumbersome so I finally decided to make an ebuild to wrap it all up. Normally, I would post this on bugs.gentoo.org but this time I am starting from a copy of the mythburn cvs which I compressed into a tar.bz2 file that I have uploaded to http://rapidshare.de/files/16603284/myt ... r.bz2.html. This file is a snapshot of the cvs version taken on 03-22-2006. I also uploaded http://rapidshare.de/files/16604105/myt ... r.bz2.html which contains the ebuild to mythwebburn along with all the current patches that I use.

About the ebuild:
Initially I started to make an ebuild for mythburn alone but I soon ran into trouble because mythburn needs to patch mythweb and needs to be installed inside the mythweb folder. After a few hours of trying to force my mythburn ebuild to work with the stock mythweb ebuild, I gave up and I decided to make a single ebuild (mythwebburn) that was for both packages would be much simpler to write.

Anyways, after finally getting the ebuild to install properly I ran into only two problems. The first was that for some reason jeg2yuv segfaults all the time on my system and several others I have tested when converting 720x480 jpegs to a mpeg. So I patched the code to use ppm images instead. This works great but has a few problems, since the frequency specification is different with ppmtoy4m vs jeg2yuv the patch for this does not set the right frequency for pal. Also I am not 100% certain I got all instances of this patched with the right frequency and number of frames so I will double check that as soon as I can. BTW, the patch for this is named mythwebburn-0.19-useppm.patch and can be commented out of the ebuild if jeg2yuv works on your system.

The second problem I found was that commercial cutting did not work at all with my system. After tracking this down I found that there were naming problems with the variables that were used to store the result of the checkboxes on the form themes/default/mythburn/confirm.php. There are two patchs that fix this: mythwebburn-0.19-fixcut.patch and mythwebburn-0.19-fixcut-1.patch.

There are currently two other patches that I use. mythwebburn-0.19-echo-cmdline.patch will echo the arguments that are being passed to mythtvburn.sh (which is the main script runs the job). So if anything fails copy everything from just after the cmdline= to the last arg. Do not include the last arg so the line should end in either no cut or cut. Then you can execute the script directly by running /var/www/localhost/htdocs/mythwebburn/modules/mythburn/mythburnscripts/mythtvburn.sh with this arg list. You will have to change the first part of this path if your webpage is not at /var/www/localhost/htdocs.

The last patch (mythwebburn-0.19-extend-readlog.patch) extends the log list from 15 lines to 50. This is a little helpful but I believe the logging display needs some work as it does not automatically update anymore.

Installation Instructions:
1) Download the mythburn-0.19.20060322.tar.bz2 file and place it in your /usr/portage/distfiles folder.

2) Create a portage overlay at /usr/local/portage (see this for instructions http://gentoo-wiki.com/HOWTO_Installing ... ty_Ebuilds)

3) Then execute the following commands in the shell.

Code: Select all

mkdir -p  /usr/local/portage/www-apps
cd /usr/local/portage/www-apps

4) Now download the mythwebburn.tar.bz2 file into /usr/local/portage/www-apps folder

5) Then (in the shell in /usr/local/portage/www-apps) execute the following commands:

Code: Select all

tar xjf mythwebburn.tar.bz2 
cd mythwebburn
ebuild mythwebburn-0.19.ebuild digest
mkdir -p /etc/portage
echo "=www-apps/mythwebburn-0.19 ~x86 ~amd64" >> /etc/portage/package.keywords
emerge mythwebburn

After this edit /var/www/localhost/htdocs/mythwebburn/modules/mythburn/mythburnscripts/mythburn.conf I believe there is a file mythburn.conf.example that shows you what is needed.

More details to follow but it's just after midnight and I'm feeling sleepy so I'll try to get back later today...

[drescherjm]

The commercial cutting bug has been applied to the source cvs at http://sourceforge.net/cvs/?group_id=119692 so the two patches for this will no longer be necissary. When I get time I will upload a new ebuild and new snapshot.

[EDIT]I have updated the snapshot and you can now download it at http://rapidshare.de/users/L0E0P9 but I will have to get back to the ebuild later today since its 3:21 AM[/EDIT]

[drescherjm]

A new ebuild and patches have been uploaded at http://rapidshare.de/users/L0E0P9. This will replace the last version and uses the mythburn-0.19.20060329.tar.bz2 cvs soruce that has the commercial cut fix applied. There are a few differences with this new ebuild one is that it will not overwrite your old configuration files the second is that the ppm patch is not enabled by default. If you need this patch do this:

Code: Select all

mkdir -p /etc/portage
echo "=www-apps/mythwebburn-0.19 useppm" >> /etc/portage/package.use"

Note: You might want to delete the /usr/local/portage/www-apps/mythwebburn folder before untaring the new ebuild and patches because a few files were removed...

[drescherjm]

Here is a my mythburn.conf file which should better match the default locations. You will most likely have to edit the mythtvlocation, dvddir and tempdir as I doubt anyone has the same lvm configuration as me.

Code: Select all

#MythBurn config settings
myfolder=/var/www/localhost/htdocs/mythwebburn/modules/mythburn/mythburnscripts
mythtvlocation=/mnt/vg/mythdata/store

I just wanted to thank you for doing this. I was about halfway into getting Mythburn installed and running when I came across this post; I figure you saved me several hours of frustration.

I have it all running now and I've created an iso or two but haven't tested them out to see if they actually work. I did see a few errors in the log file but I'm not sure if they're important or not:

Your welcome.

I get that all the time and it seems to be harmless.

I am not sure about the other error message. I will check my logs to see if I get that one also.

Yes, I get that one too.

[drescherjm]

In the near future I will release a new ebuild that cleans everything up, since the patch for jpeg-mmx fixes the segfault problem the ppm patch will no longer be necissary. And if I get some real time I may make a cvs ebuild that pulls mythburn down directly from the source cvs.

Is it possible to have this work with double layer dvd's? maybe add a checkbox or radio button to specify a 4 gb or 9gb dvd iso.

[sgreene59]

Thanks for all your work with this. After much wrangling with Apache, I finally got the mythweb portion to work properly. When I attempt to use mythburn, I get the following error:

Error at /var/www/localhost/htdocs/mythwebburn/modules/mythburn/burndvd.php, line 126:
fopen(/var/www/localhost/htdocs/mythwebburn/modules/mythburn/mythburnscripts/conf/mythtvburnconfig.xml) [function.fopen]: failed to open stream: Permission denied

Any idea where or what this permission issue is?

Thanks,

Very, possible when I get time. I have got a peliminary cvs ebuild in the works with a patch to more accurately calculate the transcode factor when a cutlist is applied but I am trying to get some time and move the files to a web page instead of the current download.

I believe the allow_url_fopen has to be set to on in your /etc/apache2/php.ini file

Code: Select all

allow_url_fopen = on

[sgreene59]

Allow_furl_open was already set to On.

I also checked <Directory> in httpd.conf and set Options All. Also to no effect. TIA if you can shed some light here.

[drescherjm]

I'm am not sure what causes this. I actually had a similar error once when I started to create the ebuild but I fixed it and I don't remember what I did. It may have been a permissions problem on the temp folder but I don't remember...

[sgreene59]

All my /var/www/localhost folders are root:root. I did set up an apache group, but I wasn't sure how to use it securely, so I haven't made it an owner. What permissions do you have set on these folders?

apache:www-data on the webhost, the myth folders that contain the recorded programs, and also the temp dvd and iso folders.

[sgreene59]

Is there a howto that describes setting apache groupid and permissions? By default, Gentoo creates neither an apache group, nor a www-data user. I really hesitate to add groups and users unless I'm sure what I'm doing. TIA.

[sgreene59]

I've cleared out most of the errors. The key now appears to be that the file /var/www/localhost/htdocs/mythwebburn/modules/mythburn/mythburntemp/mythburn.log has to exist and be writable by apache.

I also get this message in the apache log.

Symbolic link not allowed: /var/www/localhost/htdocs/mythwebburn/images/mythburn/highlightthumbnails,

Not sure yet if this is pooching things. The Mythburn page now says

The last command the scripts processed was

mplex -o /store/mythburn/temp/1051_20060413190000.mpg -f 8 1051_20060413190000.m2v

which resulted in the following errors

I should note that this is a DVB-ATSC recording. When transcoding, I get numerous errors like

The original recording was 1280x720p. Unfortunately, I don't have an analog card on this system to try.

I am having the same problems that you had with the Permission Denied problems toward the beginning of your post, and I have set all permissions on files and directories as indicated, but I cannot circumvent the problem. Would you mind telling me what you needed to do in order to resolve this? Please advise.

Thanks!

First thing, I went to the CVS version of mythburn, which seems to have fixed a lot of the problems it used to have with myth 0.19.

Second edit /etc/apache2/vhosts.d/00_default_vhost.conf

Set furl_open=on in this file. It seems to be more critical than the httpd.conf. Also I noticed the CVS version expected to find tcrequant in /usr/local/bin. Put a symlink there.

Hope this helps...

shg

[drescherjm]

I was planning on fixing any ouststanding issues and other enhancements to this however mytharchive is planned to be in the next mythrelease which was promised to be released soon so I am waiting...

[drescherjm]

Set furl_open=on in this file.

Ahh... That is needed to get some parts of mythweb running so I did not experience this problem with mythburn as I had set this months before I had used mythburn...

[mweber88]

Second edit /etc/apache2/vhosts.d/00_default_vhost.conf

Set furl_open=on in this file.

Hmm... I don't have this file, and I checked all the other apache .conf files for that entry, but no dice.

Should I put it into httpd.conf, or create its own .conf file and put it in there?

I would go ahead and put it into httpd.conf. I have PHP5, not sure, but this may be the difference. I'm running apache-2.0.55-r1 and php-5.1.4.

For what it's worth the vhosts.d directory has only one file, 00_default_vhost.conf. Here is mine:

#
# This should be changed to whatever you set DocumentRoot to.
#

I'm looking forward to mytharchive, too. Apparently mythburn can't handle hdtv broadcasts.
