Zuki

Getting this when i try and uncomopress your matrix.tar.gz file

tar zxvf matrix.tar.gz
technikz/the dvd is under /home/me/dvd/DVD/dvd and you can test it whith:

xine dvd:/home/me/dvd/DVD/dvd/VIDEO_TS
technikz/images/
technikz/images/home.gif
tar: Skipping to next header

gzip: stdin: invalid compressed data--format violated
tar: Archive contains obsolescent base-64 headers
tar: Child returned status 1
tar: Error exit delayed from previous errors

I have tried gunzip also.. just thought i'd let you know. I have tried it with a small avi file and the syncing is perfect - excellent. I don't have a /home/bogler/dvd/DVD/dvd directory with VIDEO_TS files, how are these files created? Should i get these files if i convert an avi to DVD via the script? Sorry to be such a noob
:oops:

Hello,
I am glad this thread is still active. I have looked but I don't find any news on the mpeg2enc bugs.

I just try to make the NTSC DVD menu but its failing. Is this a problem with mpeg2enc or the switches I use?


jpeg2yuv -n 50 -I p -f 29.97 -j matrix_menu_background.jpg | mpeg2enc -n n -f 8 -o matrix_menu_background.m2v


to debug i first try jpeg2yuv then I try mpeg2enc ...
shell# jpeg2yuv -n 50 -I p -f 29.97 -j matrix_menu_background.jpg > video 2>STDERR

STDERR is this

I am not sure what version ( 1.6.2 but r2 ? I don't know )
I go it last week from
http://umn.dl.sourceforge.net/sourceforge/mjpeg/mjpegtools-1.6.2.tar.gz

I just took a look at the site to confirm the version but it seems to be down at the moment.

Is it posible that the images I am usrng are at fault? I am trying every thing from the original post ( very cool indeed! ) .

With -n p ( pal ) and -f 8 OR -n n with out -f 8 I have no problems

Thanks you,

This is a really incredible thread! Thanks a ton!

But....

did anybody ever come up with a fix for the problem where the transcode process tacks a 10 pel or so bar to the bottom of the resultant video? I'm working on a mpeg4 file already at 352x240, so I tried with and without the -Z option, and got the same result.

Here's the command used:

transcode -i file.mpeg4.avi -V -y mpeg -F d -Z 352x240 --export_fps 29.97 --export_asr 2 -E 48000 -b 224 -o file

My ver. transcode is 0.6.12-r1, and mjpegtools is 1.6.2-r3

Thanks, y'all!
Bill

Zuki

I have pm'd you regarding a problem i am having.
Here are the details...

The file i am using is a movie trailer i have named Star.avi

Apologies for the hassle

I still haven't been able to burn a dvd of an avi. I have placed a small avi in directory mov. I then run the script ./mkdvd.sh -r 352x288 -f mov/* which goes off fine and transcodes the avi and places it in ready.

I encounter an error before i get to dvdauthor - it is saying -

I am slightly confused - at this stage i have directories

DVD which is empty

images - background.jpg high.png sel.png trans.png

menu - titles.xml

mov - which is empty

tmp - background.mpa spumux.xml

ready - which has the avi

Any help greatfully received - thanks a lot, your script is amazing

@zuki:

I am testing your script in the moment.
I mean, I am testing it since 19hrs.... ;)

Encoding the videos was not the problem, but jpeg2yuv and mpeg2enc is still calculating (>12hrs).
Is this normal for a xp2400+?
And the background.m2v is now 2GB huge, still growing...
I think, I stop it now...;)

Any hints what could have went wrong?

6 Movies á ca.700MB, background.jpg ca. 68KB.
started with "./mkdvd.sh -r 352x288 -f mov/*"

@theduke666

@zuki

I tried to use my own:
> http://theduke.homelinux.org/pics/background.jpg

I transformed it according to the documentation (720x576, 75/80dpi).

btw, I didn't change anything within the script.
"Confusing" is the right expression...

[edit]
I've uploaded the whole "tmp"-directory without the background.m2v (2,6GB...).

Filelist (replace with "background.jpg" in the url above):

background.jpg

highlight-1.png
...
highlight-6.png

out-1.jpg
...
out-6.jpg

selec-1.png
...
selec-6.png

I hope, it helps.
I will retry later with the new script, one small video and your pic!

cya,

@zuki:

I have it!
Pics are ok, your script is ok, was my fault:
I updated mjpegtools from 1.6.1.90-r2 to 1.6.2-r3... :oops: , now it works.

Sorry for the disagreeableness and thank you for your attention.
Your script is great, keep on going!

The script runs fine now. I have another question however.
Once the script has run, there should be a DVD (i.e. VIDEO_TS) etc in the DVD directory?.. is this correct? should this happen for avi and mpg files (placed in mov)? I am getting an mpeg 2 stream i.e. film.mpg. in DVD but it is not a DVD.

If i place an avi in mov and run the script what can i expect in the DVD directory? I don't seem to be getting the necessary DVD structure i.e. VIDEO_TS etc and i am not getting zuki's menus or anything, when i play the file it is exactly the same as the original file i.e. no menus at beginning.

How do i get from this stage to a file that can be burned and played on a DVD?

Thanks

bogler

Please watch out what the script says... The DVD directory holds the encoded movies (when you chooce delete temporary files it will be lost) the ready directory holds your old clear encoded movies, the tmp directory temporary files. And the dvd directory holds the dvd with VIEDEO_TS and so....

can we read SPRMs or write GPRMs variables with any open source dvd authoring software?
If no, do you think that it would be hard to add this feature to dvd author for instance?

you can choce english in the right top corner :-))))
download and extract the files in a directory (e.g /home/me/dvd/).

copy some videos in /home/me/dvd/DVD/mov
change dir /home/me/dvd/DVD/ and then
(chmod +x for mkdvd.sh)
./mkdvd.sh -r 352x288 -f mov/*

Then go and eat a pizza....
When all is done all clear transcoded files are moved to /home/me/dvd/DVD/ready

the dvd is under /home/me/dvd/DVD/dvd and you can test it whith:

xine dvd:/home/me/dvd/DVD/dvd/VIDEO_TS

enjoy


Zuki - Success i now have a working version of spumux and the script has built an AUDIO_TS and VIDEO_TS directory and everything seems good.

I tried the above command with xine to play the movie back but xine complains about the wrong MRL and is unable to play the movie.

Once again advice greatfully received... 8O

For what it's worth, I was also having the problem where the "jpeg2yuv | mpeg2enc" step was seemingly taking forever. Upgrading from 1.6.1.90-r2 to 1.6.2-r3 solved that problem.

zuki, thanks for the interesting script, but I have a few questions.

First, on aspect ratios. I have some videos in widescreen format that I'd like to make DVD's out of, will using either of the sizes "stretch" the video up and down, or will it just make it the proper width and leave the same aspect ratio?

Second, is the script smart enough to only make a 4.7Gb DVD? I've got directories with 6-10gig of compressed video files, but I'm not exactly sure how large each one will be when converted to mpeg2. Is there a good way to make it stop converting at 4.7Gb?

Thanks-

Hi Everyone,

Zuki, I have a question, too:

Why does the script convert an avi into an avi first?
Is this really necessary? Converting always reduces quality, I think.
Why can't we get the necessary mpg's in one converting-step.
Maybe the Script can recognize the Fileformat like Ripmake. http://www.lallafa.de/bp/ripmake.html

Thanks for your good work!

I see there are those of you, like me, who are not getting useful m2v files out of transcode, but instead getting something that promptly crashes mplayer. I seem to have solved it with a suggestion from earlier in the thread to use ffmpeg. The exact command I use is:
Code:

transcode -i filename.avi -V -y ffmpeg,mp2enc -F mpeg2 -Z 352x240 --export_fps 29.97 --export_asr 2 -E 48000 -b 224 -o filename

This gives me the same m2v/mpa files I should have gotten with the other codecs, but they don't crash mplayer. However, I do have to run all my avi's through mencoder first in an avi -> avi transform, or else transcode only does ~150 frames and stops. Has anyone seen this?

EDIT: Oh yeah, ffmpeg is about 3x faster as well, which more than makes up for the lost time doing the mencoder step.
